[julia-users] Re: Errors while trying to use cxx and embed Julia together

[Kostas Tavlaridis-Gyparakis]

Hello again,
I am experiencing the following difficulty.
So I have the above mentioned header and cpp files that define
the class ArrayMaker  on top of that I wrote a small main connected
to this class that simply excecute its function:

main.cpp:

#include "ArrayMaker.h"
#include 
using namespace std;

int main(int argc, char ** argv) {
ArrayMaker* FI_CSP=new ArrayMaker();
int a = 7;
float b = 4;
double z;
z = FI_CSP->ArrayMak(a,b);
cout<

[Kostas Tavlaridis-Gyparakis]

Ok, this did solve my problem.
Now I will proceed with trying to connect a big c++ project with julia and
see what happens there, in the very optimistic case where I proceed without
any problems I will let you know just for reference, otherwise I will 
return with
the new errors and mistakes I receive.
Thanks a lot for all the help and suggestions so far!

[Kostas Tavlaridis-Gyparakis]

Hello again,
After following the above mentioned instructions of Jeff managed to make 
Cxx working properly in the julia version
installed via (make install), yet again the original problem persists.
Just to remind you:

I have the following c++ class:

1) cpp.file:
#include "ArrayMaker.h"
#include 

using namespace std;


ArrayMaker::ArrayMaker() {
// TODO Auto-generated constructor stub

}

ArrayMaker::~ArrayMaker() {
// TODO Auto-generated destructor stub
}


double ArrayMaker::ArrayMak(int iNum, float fNum) {

jl_init(JULIA_INIT_DIR);

   jl_load("/home/kostav/.julia/v0.4/loleee/src/loleee.jl");
   jl_value_t * mod = (jl_value_t*)jl_eval_string("loleee");
   jl_function_t * func = 
jl_get_function((jl_module_t*)mod,"funior");


jl_value_t * argument = jl_box_float64(2.0);
jl_value_t * argument2 = jl_box_float64(3.0);
jl_value_t * ret = jl_call2(func, argument, argument2);

sol =  jl_unbox_float64(ret);

jl_atexit_hook();
return sol;
}
}

2) header file:
#ifndef ARRAYMAKER_H
#define ARRAYMAKER_H

#include 

class ArrayMaker
{
public:
ArrayMaker();
virtual ~ArrayMaker();
double ArrayMak(int, float);
};
#endif

Which are called isnide this small julia file:

using Cxx

# Importing shared library and header file
const path_to_lib = "/home/kostav/Documents/Project/julia/cle"   
  
addHeaderDir(path_to_lib, kind=C_System)
Libdl.dlopen(path_to_lib * "/test.so", Libdl.RTLD_GLOBAL)

cxxinclude("ArrayMaker.h")
maker = @cxxnew ArrayMaker()

a = @cxx maker->ArrayMak(5, 2.0)
 println("return value is: ", a)


As described above what I am trying is to call the c++ function ArrayMak 
from julia file,
where inside this function I call an other julia function (called name 
"funior") that just receives
two numbers as arguments and returns their sum.
More or less want to verify that I can have the following process:
Julia file -> Calling C++ classes -> calling inside them other julia 
functions -> returning arguments from the C++ classes to the original julia 
file.
So when I run the julia file everything works until the moment that the c++ 
function needs to return the argument to julia file, I have checked
and confirmed that until that point everything works proprely:
1) C++ function ArrayMak is called
2) Function funior is receiving the arguments properly and returns to the 
variable sol the sum of the two arguments
But when the value of sol needs to be returned to the julia function 
everythins stucks.
Judging from the example in the cxx web-site in order to return arguments 
from c++ functions to julia you don't need to do anything complicated
or different from what is shown here:


arr = @cxx maker->fillArr() (where fillArr is supposed to return an array)

So, I am not sure what is going wrong here...

If I get this right does it mean that for all the files that are included 
in the list "  * DirectoryLayout* 
"
I need to create a soft link to link them with the directory 
"/usr/local/julia/lib" (which doesn't exist
in my system)?
Aslo regarding the instructions of part "*BuildJuliaLLVMforCXX* 
"
 
where you present the files that
need to be cp to the directory julia-f428392003 in my system I face the 
following problems:

1) The image files (sys.ji, sys.dylib,sys-debug.dylib) don't exist anywhere 
in my system
2) The folder llvm-svn (in the source julia directory) has completely 
different structure in my system,
In my julia (source code) folder there are two folders with the name 
llvm-svn the one has a structure
that you can look in the attach picture called name (llvmsn), while the 
second one is located in the
path "/home/kostav/julia/usr-staging/llvm-svn" and has a single folder 
named "build_Release+Asserts".

All in all I am confused on how to follow your instructions (for which I do 
really appreciate the effort you
put to provide me with). Is what I have to do:

1) Try to copy paste the folders as presented in "*BuildJuliaLLVMforCXX* 

"?
2) Create links for all the files listed * "DirectoryLayout" * 
towards
 
the folder "/usr/local/julia/lib"?

[Kostas Tavlaridis-Gyparakis]

Hello,
Once again I really appreciate all the effort you put and the help you 
provide.
I assume that since you made things work properly now we do havea working
solution.
Yet again as I am not really good with programming in general sth things I 
still
unfortunately need to ask on how to follow your directions.
So,


Step 1.  Build and run make install
> Step 2.  While still in the top level source directory, install Cxx as per 
> the Cxx webpage

These three steps I have already done, I have compiled the source code and 
installed Cxx
accordingly for the source code and I also have copied the installed 
directory (the one with the big 
number that is created after make install) in a seperate file from which I 
run julia.

Step 4.  There are additional include files that Cxx needs access to after

>

Here I am a bit confused what to do. I did cp the abve mentioned 
directories:

cp -a /usr/lib/clang /home/kostav/Julian/julia-f428392003/lib
cp -a /usr/include/{clang,llvm-3.6,llvm-c-3.6} 
/home/kostav/Julian/julia-f428392003/include

But then in the gist I see you do cp a bunch of other files which I am not 
sure I do have them all anyway.
Does this mean that instead of copying the above mentioned directories I 
included I need to copy the spe-
cific files you point out in the first session of the git ( i.e. 
*BuildJuliaLLVMforCXX* 

)?

Step 5.  In addition for embedding the relative paths are off, so a couple of 
symbolic links need to be added.
>
>
Symbolic links to link which files though?
Sorry if the questions I raise are already answered by the git, I just 
failed to understand it properly so that's
why I come back with these questions now.

[Kostas Tavlaridis-Gyparakis]

Hello again and thanks a lot for the suggestions.
Thing is, I went back to the source version of Julia where Cxx is already 
built and
runs properly, so there wasn't much for me to do, I run in terminal also 
the command of:

"addHeaderDir("/home/kostav/julia/src/")"

Then proceeded again with make install and run the version of julia from 
this folder but
still not being able to use or install Cxx. So, maybe I didn't understand 
properly what you
were suggesting for me to do in the source version of Julia...
Or maybe there is sth else I should try..?

[Kostas Tavlaridis-Gyparakis]

Hello,
Just to be sure that I am understanding correctly what your proposal.
You suggest I should:

1) Completely uninstall Julia
2) Recompile the source code (i.e. run make)
3) Then try using julia from the source code build cxx package
4) Then perform the make install and link the version of julia of the 
decaxemical folder with my system
And hopefully this will work?
I am just asking to be sure before I proceed with any attempt, as the make 
command is really time con-
suming, so want first to be sure that I am doing what you are actually 
suggesting (:

Hello again,
Latest news are the next:
Following the advice of the previous thread I am now running julia from the 
path where
I copy-pasted the directory that was created from make-install (the one 
with the big number)
this did solve the issue of being able to call julia functions from inside 
c++ initializing with 
the command: jl_init(JULIA_INIT_DIR);
And by having in the makefile the following commands:

CFLAGS   += $(shell /home/kostav/julian/julia-f428392003/bin/julia  
/home/kostav/julian/julia-f428392003/share/julia/julia-config.jl --cflags)
CXXFLAGS += $(shell /home/kostav/julian/julia-f428392003/bin/julia  
/home/kostav/julian/julia-f428392003/share/julia/julia-config.jl --cflags)
LDFLAGS  += $(shell /home/kostav/julian/julia-f428392003/bin/julia

Now I also run and compiled the above code of ArrayMake.cpp, ArrayMake.h

And until that point everything works smoothly. Yet agian the problem is 
that the Cxx is not installed in this julia directory
and when I try to install it I receive the following error:

[Kostas Tavlaridis-Gyparakis]

Hello again,
And once again thanks for the constant support you are providing it has been
really helpful so far.
So, I did follow all of the steps you suggested and cp the directory with 
the name
with the big number to an other file changed the soft link and also the 
make file,
and this did finally work!
So, I am really grateful for your persistant help and support.
Now I will focus in the other problem I am facing in the new post regarding 
trying
to call c++ function from julia that inside them calling other julia 
functions.
As I will be afk today for the rest of the day probably will return on this 
until tomorrow.
Once again thanks for all the help and support is much appreciated!

[julia-users] Errors while trying to use cxx and embed Julia together

[Kostas Tavlaridis-Gyparakis]

Hello again,
I am running Julia Version 0.4.0-dev+5841 (installed from source code) 
and currently run Ubuntu 15.04.
I am trying to write a julia file that will call some c++ classes and 
functions, where inside
these functions some other Julia functions will be used and I face some 
errors.
Let me get things one by one.

This is my c++ files: 

1) The cpp of the class (ArrayMaker.cpp):

#include "ArrayMaker.h"
#include 
using namespace std;
ArrayMaker::ArrayMaker() {
// TODO Auto-generated constructor stub
}
ArrayMaker::~ArrayMaker() {
// TODO Auto-generated destructor stub
}
double ArrayMaker::ArrayMak(int iNum, float fNum) {
jl_init_with_image("/home/kostav/julia/usr/lib/julia", "sys.so");
jl_eval_string("print(sqrt(2.0))");
cout << "Got arguments: " << iNum << ", and " << fNum << endl;
 double sol;
  jl_load("/home/kostav/.julia/v0.4/loleee/src/loleee.jl");
jl_value_t * mod = (jl_value_t*)jl_eval_string("loleee");
jl_function_t * func = 
jl_get_function((jl_module_t*)mod,"funior");
jl_value_t * argument = jl_box_float64(2.0);
jl_value_t * argument2 = jl_box_float64(3.0);
jl_value_t * ret = jl_call2(func, argument, argument2);
sol =  jl_unbox_float64(ret);
iNumber = iNum;
fNumber = fNum;
fArr = new float[iNumber];
jl_atexit_hook();
return sol;
}
float* ArrayMaker::fillArr() {
cout << "Filling the array" << endl;
for (int i=0; i < iNumber; i++) {
fArr[i] = fNumber;
fNumber *= 2;
} 
return fArr;
}

2) The equivelant header file (ArrayMaker.h):

#ifndef ARRAYMAKER_H
#define ARRAYMAKER_H
#include 

class ArrayMaker
{
public:
ArrayMaker();
virtual ~ArrayMaker();
double ArrayMak(int, float);
float* fillArr();

private:
int iNumber;
float fNumber;
float* fArr;
};
#endif

3) The main file (main.cpp):

#include "ArrayMaker.h"
#include 

using namespace std;

int main(int argc, char ** argv) {
ArrayMaker* FI_CSP=new ArrayMaker();
int a = 7;
float b = 4;
double z;
z = FI_CSP->ArrayMak(a,b);
cout

Ok, thanks a lot for all your help for the moment I stay with just using a 
makefile
and include the paths following the above example case that does work.

Sorry for the delay in my answer.



*>Could you run /home/kostav/julia/contrib/julia-config.jl  --ldlibs and

I downloaded the source code in folder (home/julia) and run inside this 
file make 
and make install of Julia inside.

*>**/home/kostav/julia/bin/julia  /home/kostav/julia/contrib/*julia-config.jl

I actually don't have any bin folder inside my julia folder, so I can't do 
any of
the suggested modifications.
What could I do different in this case?

Thanks a lot, that fixed this error, but now it returns me the same error 
that I get when I just run the compile command
in terminal:

fatal error: julia.h: No such file or directory  #include  
compilation terminated.

Re: [julia-users] Re: Embedding Julia with C++

[Kostas Tavlaridis-Gyparakis]

Thanks a lot for the answer.
I have located the path of julia-config (/home/kostav/julia/contrib) and I 
did try to run it with setting this path.
Both by just writing the command in the terminal: 

/home/kostav/julia/contrib/julia-config.jl --cflags --ldflags --ldlibs | 
xargs gcc embed_example.c

But I do receive error saying that: fatal error: julia.h: No such file or 
directory  #include 


Or via the makefile, which I change accordingly into this:

CFLAGS   += $(shell $/home/kostav/julia/contrib/julia-config.jl --cflags)
CXXFLAGS += $(shell $/home/kostav/julia/contrib/julia-config.jl --cflags)
LDFLAGS  += $(shell $/home/kostav/julia/contrib/julia-config.jl --ldflags)
LDLIBS   += $(shell $/home/kostav/julia/contrib/julia-config.jl --ldlibs)

all: embed_example

And I receive the following errors: 

make: home/kostav/julia/contrib/julia-config.jl: Command not found
make: home/kostav/julia/contrib/julia-config.jl: Command not found
make: home/kostav/julia/contrib/julia-config.jl: Command not found
cc embed_example.c   -o embed_example
embed_example.c:1:19: fatal error: julia.h: No such file or directory
 #include 
   ^
compilation terminated.
: recipe for target 'embed_example' failed
make: *** [embed_example] Error 1

Let me just remind you that in the case where I use jl_init(NULL);
and I run in terminal this command:

gcc -o test main.c -I /home/kostav/julia/src -I 
/home/kostav/julia/usr/include -I /home/kostav/julia/src/support 
-L/home/kostav/julia/usr/lib -ljulia -lLLVM-3.7svn

Program does compile and the error comes when I try to run the program 
where I receive msg saying that:

error while loading shared libraries: libjulia.so: cannot open shared 
object file: No such file or directory

So, maybe it would be simpler to try to solve this one?
I don't know, again any suggestions would be really welcome!

[julia-users] Re: Embedding Julia with C++

[Kostas Tavlaridis-Gyparakis]

Hello thanks a lot for your answer.
You assumed correctly I do use version 0.4.
If I got right your proposal about the linking error is to use
the command jl_inti(JULIA_INIT_DIR) as shown in this 
 
example and use a makefile where I just copy paste the
commands shown in the example, so the makefile looks like that:

JL_SHARE = $(shell julia -e 
'print(joinpath(JULIA_HOME,Base.DATAROOTDIR,"julia"))')
CFLAGS   += $(shell $(JL_SHARE)/julia-config.jl --cflags)
CXXFLAGS += $(shell $(JL_SHARE)/julia-config.jl --cflags)
LDFLAGS  += $(shell $(JL_SHARE)/julia-config.jl --ldflags)
LDLIBS   += $(shell $(JL_SHARE)/julia-config.jl --ldlibs)

all: main


and my source code looks like that:

#include 

int main(int argc, char *argv[])
{
/* required: setup the julia context */
jl_init(JULIA_INIT_DIR);

/* run julia commands */
jl_eval_string("print(sqrt(2.0))");

/* strongly recommended: notify julia that the
 program is about to terminate. this allows
 julia time to cleanup pending write requests
 and run all finalizers
*/

Note that I have really no experience with makefiles so I can not really 
handle them
properly, but I assumed that I should be working if I did all it was saying 
in the example.
Yet again I receive the above errors.

[julia-users] Re: Embedding Julia with C++

[Kostas Tavlaridis-Gyparakis]

Hello again,
I am writing to this post, as I face some more problems with trying to link 
Julia functions with C++ code.
The thing is that I changed my current Julia version, I installed Julia 
running the source code as I wanted 
to install the Cxx package as well.
So, I just went to run the first smallest example with some c code and c++ 
code that uses a julia function
as presented here , 
so I only try to run the following file:

#include 
int main(int argc, char *argv[]){
/* required: setup the julia context */
jl_init(NULL);

/* run julia commands */
jl_eval_string("print(sqrt(2.0))");

/* strongly recommended: notify julia that the program is about to 
terminate. this allows julia time to cleanup pending write requests 
and run all finalizers*/
jl_atexit_hook();
return 0;}



The first thing that was different was that when I was including just the 
path of julia.h and libjulia.so and I
run the command like this:

gcc -o test main.c -I /home/kostav/julia/src -L/home/kostav/julia/usr/lib 
-ljulia

I receive an error saying: 

*In file included from main.c:1:0: /home/kostav/julia/src/julia.h:12:24: 
fatal error: libsupport.h: No such file or directory  #include 
"libsupport.h" compilation terminated.*

Then when I add the path of libsupport.h I receive a similar error msg 
saying that uv.h is missing so I have 
to add its path as well, and as a result I finally run the following 
command:

gcc -o test main.c -I /home/kostav/julia/src -I 
/home/kostav/julia/usr/include -I /home/kostav/julia/src/support 
-L/home/kostav/julia/usr/lib -ljulia

In that case I receive various errors about undefined references regarding 
llvm functions and as a result I include
as well the equivelant library and finally run the following command:

gcc -o test main.c -I /home/kostav/julia/src -I 
/home/kostav/julia/usr/include -I /home/kostav/julia/src/support 
-L/home/kostav/julia/usr/lib -ljulia -lLLVM-3.7svn

On this case the program does compile but when I try to run it, I receive 
the following error:




*error while loading shared libraries: libjulia.so: cannot open shared 
object file: No such file or directory*The exact same implies for the 
equivalent program in c++. Note that when I try to call a julia function 
inside a c++ more complicated 
structure (namely in a class) I receive a different error. More 
specifically just for the very simple class that exists
in this Cxx example 
 
for just using the same simple julia function inside the class that leads 
to the following slighltly different cpp file

#include "ArrayMaker.h"
#include 

using namespace std;

ArrayMaker::ArrayMaker(int iNum, float fNum) {

jl_init(NULL);
jl_eval_string("print(sqrt(2.0))");

cout << "Got arguments: " << iNum << ", and " << fNum << endl;
iNumber = iNum;
fNumber = fNum;
fArr = new float[iNumber];
jl_atexit_hook();
}

float* ArrayMaker::fillArr() {
cout << "Filling the array" << endl;
for (int i=0; i < iNumber; i++) {
fArr[i] = fNumber;
fNumber *= 2;
} 
return fArr;
}

With the header file being almost the same:

#ifndef ARRAYMAKER_H
#define ARRAYMAKER_H

#include 

class ArrayMaker
{
private:
int iNumber;
float fNumber;
float* fArr;
public:
ArrayMaker(int, float);
float* fillArr();
};

#endif

When I try to compile in terminal using the following command:

g++ -o test ArrayMaker.cpp -I /home/kostav/julia/src -I 
/home/kostav/julia/usr/include -I /home/kostav/julia/src/support 
-L/home/kostav/julia/usr/lib -ljulia -lLLVM-3.7svn

I do receive the following error: 

/usr/lib/gcc/x86_64-linux-gnu/4.9/../../../x86_64-linux-gnu/crt1.o: In 
function `_start': 
/build/buildd/glibc-2.21/csu/../sysdeps/x86_64/start.S:114: undefined 
reference to `main'
collect2: error: ld returned 1 exit status



I am really not sure how to resolve any of the two errors and in general 
the second one is also pretty important to me, as in general my end goal
is starting from a julia file to use my self-written c++ code, where inside 
the c++ code I call some other self-written julia functions, I know it does
sound kind twisted, but that's what I am interested to do, as I am trying 
to tackle a big Mathematical Problem by builing the original problem in Jump
then decompose it and use a solver that is written in c++ (that's why I 
need to call c++ inside julia) which then needs again to send back 
information
to the original model and probably solve some subproblems with CPLEX 
(that's why I will need inside the c++ code to call julia functions again). 
That
with as much as few words as possible in order not to bother you with a lot 
of unnecessary information.

Re: [julia-users] Errors while trying to install Cxx Package

[Kostas Tavlaridis-Gyparakis]

Ok, this did work.
Thanks a lot for the suggestion.
I actually haven't proceeded with trying this, cause I thought that since 
the moment julia command was not working
inside the source folder the problem had to do with the installation itself 
and not with linking.
My mistake. Thanks a lot for all your answers and help hope now will be 
able to use Cxx.

I did open both locations in terminal and type julia and I still get the 
same msg that: 

"The program 'julia' is currently not installed. You can install it by 
typing:
sudo apt-get install julia"

Unless if you were meaning sth else and I missunderstood your suggestion

Re: [julia-users] Errors while trying to install Cxx Package

[Kostas Tavlaridis-Gyparakis]

Thanks a lot for pointing out the above mentioned part of the Readme file I 
have had a look on it as well and tried
also to add the prefix line in Make.used but also didn't work.
Also both 'julia/usr/bin/julia` and `julia/usr/bin/julia-debug` do exist.
Make, maketest and make-install all run without any error msg.
What else could I try?

Re: [julia-users] Errors while trying to install Cxx Package

[Kostas Tavlaridis-Gyparakis]

I downloaded the julia file and located them in the home directory 
("/home/kostav/julia")
then I run make, make test and make install as well.
All of them seem to work.
Then when I try to run julia command in terminal opening terminal 
from the file where the source is located ("/home/kostav/julia"), I receive
a msg saying that julia is not installed.
In the usr/bin there is no folder or file under the name julia.
I am really not sure what to do to fix this, and since I want Cxx package
I do need the source code installation...

Re: [julia-users] Errors while trying to install Cxx Package

[Kostas Tavlaridis-Gyparakis]

Finally manage to run make command with no errors.
Yet again after this I perform make test and everything seems to be fine.
Then I run make install and once its finished, I try to run Julia command in
terminal in the path where the julia source file is located but I receive 
msg
saying that I don't have julia installed.
Any idea on how to proceed with this?

Thanks a lot once again.
So after fixing this a few more errors I am stacked with the following 
error msg:

You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this
state without impacting any branches by performing another checkout.

If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -b with the checkout command again. Example:

  git checkout -b new_branch_name

Re: [julia-users] Errors while trying to install Cxx Package

[Kostas Tavlaridis-Gyparakis]

Ok, thank you pointing that out.
So, I need to uninstall my current version and install using the source 
files.
Just two questions really noob ones.
In the read me file, it says that I need to add the following lines to a 
Make.user:

override LLDB_VER=master
override LLVM_VER=svn
override LLVM_ASSERTIONS=1
override BUILD_LLVM_CLANG=1
override BUILD_LLDB=1
override USE_LLVM_SHLIB=1
override LLDB_DISABLE_PYTHON=1

Does this mean that I just create a file with the name Make.user and copy paste 
this line
on the file and then save it in the directory where the source file is 
downloaded?
Also when you say "ne that uses LLVM-svn" not sure what I need to check for 
this one.

Re: [julia-users] calling julia functions in C++

[Kostas Tavlaridis-Gyparakis]

Ok, thanks a lot it did work just fine!
just one more quick question, if I got it right jl_call1 is for adding one 
input argument to the functions and jl_call2 is for adding two input 
arguments to the function.
For adding more arguments I continue in the same way? For instance for 4 
arguments I just use use jl_call4?
Or what I am saying is completely mistaken?

Re: [julia-users] calling julia functions in C++

[Kostas Tavlaridis-Gyparakis]

Ok, so first of all thanks a lot for all the help so far.
So, now I try to follow the instructions and I write the following three 
lines of code inside C++:

 jl_load("mymodule.jl");
jl_value_t * mod = jl_eval_string("mymodule");
jl_function_t * func = 
jl_get_function(jl_new_module(mod),"myfunction");

(the jl file and the module itself have the same name in this case mymodule)
But I do receive the following 2 errors when Eclipse compiles:

1) error: invalid conversion from ‘void*’ to ‘jl_value_t* {aka 
_jl_value_t*}’ [-fpermissive] (this is referring to  jl_value_t * mod = 
jl_eval_string("mymodule");)

2) error: cannot convert ‘jl_value_t* {aka _jl_value_t*}’ to ‘jl_sym_t* 
{aka _jl_sym_t*}’ for argument ‘1’ to ‘jl_module_t* 
jl_new_module(jl_sym_t*)’ (this referring to jl_function_t * func = 
jl_get_function(jl_new_module(mod),"myfunction");)


>No problem, no stupid questions. However, I would suggest that you might 
want to spend some time getting really familiar with Julia by itself, 
before trying to use the embedding API. It might save a lot of time in the 
long run.

You are totally right on this, I am just trying first to check if it is 
doable to do some combinations between C++ in Eclipse and Julia (such as 
using functions written in
Julia inside a C++ routine etc), because I am planning to connect a 
large-scale C++ with Julia and before starting to studying Julia in full 
detail and start writing proper
code was thinking to do some small tests in connectivity between the two. 
But it turns out that I don't know some very basic things to finish this 
task.

Sorry but I am not sure what you mean and how to "*evaluate your .jl file 
defining the module first*"?
(I am really new to Julia so maybe the question sounds really stupid, sorry

[julia-users] calling julia functions in C++

[Kostas Tavlaridis-Gyparakis]

Hello,
I am trying to write some function in Julia which I will be able to call 
inside my C++ projects in Eclipse.
In the documentation there is this 

 
example on how to call a function of julia from an existing module.
So, what I have done was to create my own module where inside I included my 
function and then my
understanding is that I should be using "jl_new_module(jl_sym_t *name);" 
instead of jl_base_module.
But I am not sure (in case my assumption that this is the correct command 
is true) how to proper use
it's syntax, as what I am trying is:

jl_function_t * func = 
jl_get_function(jl_new_module(mymodule),"myfunction");

and I tried instead of mymodule also mymodule.jl and "mymodule" and 
"mymodule.jl" and in all the attempts I
recieve an error that:

mymodule  was not declared in this scope


Let me note beforehand that the module is being stored globaly as when I run 
julia on the terminal I can use it
through the comand using mymodule.
Still maybe I am trying to use the wrong command or sth, so if there is any 
suggestion I would be really greatful
to hear it.

Re: [julia-users] Embedding Julia with C++

[Kostas Tavlaridis-Gyparakis]

Sorry didn't get your question.
In general the problem is that Eclipse doesn't seem to be able to 
recognize/include this sys.ji file, and I
don't know how to fix it.

Νο, unfortunately it's not that.
I just gave to the project the name "juli" I forgot to type the a and 
didn't bother correct it aftewrards, so
the path name is correct.

Re: [julia-users] Re: Embedding Julia with C++

[Kostas Tavlaridis-Gyparakis]

I am simply trying to run the first example attached in the embedding 
documantation which is the following block of code:

#include 
#include 
using namespace std;

int main() {
  /* required: setup the julia context */
jl_init(NULL);

/* run julia commands */
jl_eval_string("print(sqrt(2.0))");

/* strongly recommended: notify julia that the
 program is about to terminate. this allows
 julia time to cleanup pending write requests
 and run all finalizers
*/
jl_atexit_hook();

return 0;
}

And when I try to run the program in eclipse (after having linked the 
library and defined the path of the header file) the above mentioned
error message appeas which says:

- System image file 
"/home/kostas/workspace/juli/Debug/../lib/x86_64-linux-gnu/julia/sys.ji" 
not found

[julia-users] Re: Embedding Julia with C++

[Kostas Tavlaridis-Gyparakis]

I did download the 0.4 nightbuilt which includes the above mentioned files 
in the proper location, but now Eclipse is throwing me a different
error I can not sort out how to overcome. When I try to run a small cpp 
file with a few julia comands Eclipse is compiling the file but when I
try to run it it throws me the following message:

"System image file 
"/home/kostas/workspace/juli/Debug/../lib/x86_64-linux-gnu/julia/sys.ji" 
not found "

Futhermore since I am really new to Julia I am not sure and I don't know a 
lot of the existing tools, is it possible to write a function in julia
that takes as an argument some data creates a model and solves it and call 
this function from inside my c++ project?
I am asking this as in the example in the link 

 
attached by Isaiah with the qsort, the whole process is done inside julia 
framework.
Whereas in my case I would be interested to write a julia program, like the 
one described above that I would be able to call as a function 
(I want it to solve a subproblem actually) inside my c++ project in eclipse.
Is this relatively easy to be done?
Because I think this would be the best approach for my case.

[julia-users] Embedding Julia with C++

[Kostas Tavlaridis-Gyparakis]

Hello,
I am trying to embed Julia in C++ but I currently face some sort of issues.
I am trying to follow the instructions shown here 
.
First things first, I run Ubuntu 15.04 and my Julia version is v. 0.3.2 
(it's the 
version that is automatic installed when installing julia from ubuntu 
center).
I use eclipse for my C++ projects, yet again I have the following issues, 
ac-
cording to the instructions before trying to write any julia code in C or 
C++ you
need first to:
1) link the julia library (assuming I undersand correctly this refers to  
libjulia.so),
which should be located in "Julia_DIR/usr/lib", yet again in my julia 
directory
there is no folder under the name usr. I did though find a libjulia.so file 
in an
other directory of my pc ("/usr/lib/x86_64-linux-gnu/julia") and added this 
one
instead.
2) include the path of julia.h which should be located in 
"Julia_DIR/inclue/julia"
now again in my julia directory there are no such folders and in general 
there
is nowhere in my pc any file such as julia.h. I did sth that is probably 
wrong 
and stupid but couldn't come up with anything else I downloaded this 
 and I
included the location of where julia.h is located to eclipse as well with 
the direc-
tions of all the other header files that were inculuded inside julia.h.

Now when in Eclipse I am trying to compile and run a few simple julia 
commands
having included julia.h i receive an error saying that there is no uv.h 
file in my
system which is needed in one of the julia header files.
I know that my whole approach is wrong, but yet again I couldn't find 
anywhere
in my pc the proper folders or files in order to follow the steps that were 
sugges-
ted in the julia website for running julia code inside C++.
Any help would be much appreciated.

Also, one more thing I wanted to ask is the following, in general writing 
Julia
code inside a C++ code is limited?
What I want to do in general is write a JuMP model inside C++, so in general
is this possible, in the sense that by embedding Julia inside C++, will I 
be able
to use all of the tools and code of Julia language or is this only limited 
to a cer-
tain amount of commands and packages?

Re: [julia-users] Re: Errors while trying to use JuMP

[Kostas Tavlaridis-Gyparakis]

So finally after upgrading my OS (actually switched to Ubuntu),
JuMP finally works!
Thanks a lot for all the help, probably I will come back with other 
questions regarding 
connecting C++ code with Julia in the future, but for the moment problem 
solved!

Re: [julia-users] Re: Errors while trying to use JuMP

[Kostas Tavlaridis-Gyparakis]

The 0.3-prerelease version of Julia was installed in my machine when I 
tried to isntall julia from the terminal
by typing "sudo apt-get install julia".
I run linux mint 16 on my laptop.
When I try to apt-get install git, I receive the following error:

Traceback (most recent call last):
  File "/usr/lib/command-not-found", line 21, in 
os.execvp("python3", [sys.argv[0]] + sys.argv)
  File "/usr/lib/python2.7/os.py", line 344, in execvp
_execvpe(file, args)
  File "/usr/lib/python2.7/os.py", line 380, in _execvpe
func(fullname, *argrest)
OSError: [Errno 2] No such file or directory

Re: [julia-users] Re: Errors while trying to use JuMP

[Kostas Tavlaridis-Gyparakis]

I downloaded and extracted the version that you put in the link, but for 
some reason now, when I run
Julia on terminal the pck command doesn't seem to work.
This is the msg I get when I try to use any command related with pkd:

Pkg.status()

[Kostas Tavlaridis-Gyparakis]

Ok fixed that one, but now I have another installation problem,
I receive the following error:
/bin/sh: 2: cmake: not found
make[1]: *** [libgit2/build/Makefile] Error 127
make: *** [julia-deps] Error 2

Once I do finally manage to sucessfully install julia I will come back to 
you!

Ok, so after deleting all the julia files from my laptop
and downloading the latest version from github ( 

git clone git://github.com/JuliaLang/julia.git

), when I try to run make in the terminal after a huge run of 50 minutes
in the end the following msg is desplayed in my terminal:

checking for suitable m4... configure: error: No usable m4 in $PATH or 
/usr/5bin (see config.log for reasons).

Re: [julia-users] Re: Errors while trying to use JuMP

[Kostas Tavlaridis-Gyparakis]

The output of versioninfo() is the following:

Julia Version 0.3.0-rc1+54
Commit 4e92487 (2014-07-17 05:40 UTC)
Platform Info:
  System: Linux (x86_64-linux-gnu)
  CPU: Intel(R) Core(TM) i5-4300U CPU @ 1.90GHz
  WORD_SIZE: 64
  BLAS: libblas.so.3
  LAPACK: liblapack.so.3
  LIBM: libopenlibm


I already deleted the Docile package from the julia directory and 
reinstalled it,
but again with no luck and also again the old version of 0.1 was installed.

Re: [julia-users] Re: Errors while trying to use JuMP

[Kostas Tavlaridis-Gyparakis]

When i run update after I install Dolice there is nothing new:

Pkg.update()
INFO: Updating METADATA...
INFO: Computing changes...
INFO: No packages to install, update or remove

How can I update from terminal to julia 0.4 myself?
Also I am not quiet sure how to use clone command
to force julia Dolice to the latest version (sorry I am 
a real noob).

Re: [julia-users] Re: Errors while trying to use JuMP

[Kostas Tavlaridis-Gyparakis]

Also, if I try to update Dolice (after having deleting it from the above 
mentioned directories)
 by first typing Pkg.add("Dolice") I receive following error:

Pkg.add("Docile")
ERROR: unknown package Docile
 in wait at task.jl:51
 in sync_end at ./task.jl:306
 in add at pkg/entry.jl:314
 in add at pkg/entry.jl:71
 in anonymous at pkg/dir.jl:28
 in cd at ./file.jl:20
 in __cd#226__ at ./pkg/dir.jl:28
 in add at pkg.jl:20


I can only install it if I directly run the Pkg.update() command, which 
does install v. 0.1 as mentioned above

Re: [julia-users] Re: Errors while trying to use JuMP

[Kostas Tavlaridis-Gyparakis]

Followed your recommendation but have to note the following things:

1) I have Julia v0.3 even if I just downloaded Julia this week 
2) after deleting Dolice and running update command again the version 0.1 
was installed:

Pkg.update()
INFO: Updating METADATA...
INFO: Computing changes...
INFO: Cloning cache of Docile from 
git://github.com/MichaelHatherly/Docile.jl.git
INFO: Installing Docile v0.1.0

Only problem is that when I run the updtate command in julia I receive a 
msg that there is nothing to be upgraded:

Pkg.update()

[julia-users] Errors while trying to use JuMP

[Kostas Tavlaridis-Gyparakis]

 

Hello,
I am really new to Julia and not the best programmer mysefl.
I run linux mint 16 and I installed julia via terminal (sudo apt-get 
install julia ).
Then when I run Julia on my terminal, while the JuMP package is installed
sth that I believe the following two commands on my terminal prove:

julia> Pkg.update()
INFO: Updating METADATA...
INFO: Computing changes...
INFO: No packages to install, update or remove

julia> Pkg.add("JuMP")
INFO: Nothing to be done

Then when I try to use JuMP I get the following error msg:
