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 <julia.h>
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 <julia.h>
^
compilation terminated.
<builtin>: 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!
