Re: [cmake-developers] Shared libraries

2018-08-21 Thread REIX, Tony 
Hi Chuck,


Thanks for the information.


We launch cmake on MariaDB code with:

   -DBUILD_SHARED_LIBS=true


Moreover, here are the few places in MariaDB code where BUILD_SHARED_LIBS 
appears:

# grep -R BUILD_SHARED_LIBS *
CMakeCache.txt:BUILD_SHARED_LIBS:UNINITIALIZED=true
pcre/CMakeLists.txt:# IF(NOT BUILD_SHARED_LIBS)
pcre/CMakeLists.txt:# ENDIF(NOT BUILD_SHARED_LIBS)
pcre/CMakeLists.txt:#  MESSAGE(STATUS "  Build shared libs ... : 
${BUILD_SHARED_LIBS}")
plugin/aws_key_management/CMakeLists.txt:-DBUILD_SHARED_LIBS=OFF


What does the first line means ?


Thx/Regards,



Cordialement,

Tony Reix

Hi Tony,

I expect what your seeing is likely the result of how MaraiaDBhas specifically 
implemented their CMake build.  The only builtin CMake variable to control this 
is BUILD_SHARED_LIBS, which when set to "ON" changes the behavior of 
add_library(foo) to be add_library(foo SHARED), instead of the default 
add_library(foo STATIC).  The other BUILD_STATIC_LIBS and DISABLE_SHARED are 
variables are not builtin to CMake and are part of however they have chosen to 
implement their build.

CMake builds are typically designed to produce a single configuration, i.e. 
shared release or static debug, etc.  Often, however, because to have the 
flexibility to do otherwise. projects will try to instead implement a build 
that produces several configurations in a single pass.  It seems this is what 
MariaDB has done and as such the variables to control it will be unique and 
specific to that project and how they've decided to implement it.

It's MariaDB's CMake code that is doing that, not CMake itself.

Re: [cmake-developers] cmake on AIX

2018-06-19 Thread REIX, Tony 
Hi Brad,


Thanks for the information!


About MariaDB current issue, the only trace I see dealing with the string 
breaking cmake is:


/opt/freeware/src/packages/BUILD/mariadb-10.3.1/64bit/libmariadb/cmake/FindGSSAPI.cmake(94):
  message(STATUS Found GSSAPI: ${GSSAPI_LIBS} )
-- Found GSSAPI: -L/opt/freeware/lib -blibpath:/opt/freeware/lib::/usr/lib:/lib 
-I/usr/include -I/opt/freeware/include -L/opt/freeware/lib 
-blibpath:/opt/freeware/lib:/usr/lib:/lib
-bmaxdata:0x8000 -brtl -lgssapi_krb5 -lkrb5 -lk5crypto -lcom_err -lpthreads


It contains a part of this:

# grep bmaxdata mariadb-10.3.1-1.spec
export LDFLAGS="-L/opt/freeware/lib 
-Wl,-blibpath:/opt/freeware/lib:/usr/lib:/lib -Wl,-bmaxdata:0x8000 -lintl"

And the rest of the string probably comes from KRB5 configuration files:
# rpm -ql krb5-devel-1.9.4-2 | xargs grep lkrb5
/opt/freeware/bin/krb5-config:  lib_flags="$lib_flags -lkrb5 -lk5crypto 
-lcom_err $GEN_LIB $LIBS $DL_LIB"
/opt/freeware/bin/krb5-config_64:   lib_flags="$lib_flags -lkrb5 -lk5crypto 
-lcom_err $GEN_LIB $LIBS $DL_LIB"


So, it looks like cmake gets data for the CMAKE_REQUIRED_LIBRARIES from these 2 
aboves places, but it does not transform the " " blank separators by ";" ?!!

Any idea where this is done ?

See the Testing/* directory.  When not running in dashboard
client mode there isn't much logged though.

I suspect mariadb's source is setting CMAKE_REQUIRED_LIBRARIES
to a space-separated value instead of a ;-separated value.

See the code here:

  
https://github.com/MariaDB/server/blob/ed0b84a027/plugin/auth_gssapi/CMakeLists.txt#L22-L24

It assumes GSSAPI_LIBS is ;-separated, but the cache entry you
quoted is a command-lien string with spaces.

Re: [cmake-developers] cmake on AIX

2018-06-19 Thread REIX, Tony 
Hi,


We moved to AIX 7.1 . With cmake 3.11.4 .

In this environment, we were able to build cmake. However, there are 7 cmake 
tests which fails.


When using this cmake for building MariaDB, it fails with an unclear error 
message (see below). Any idea ?


We'd like to investigate and fix these 7 failing tests (at least those that 
look important).

However, we've found yet no information about how to:

   a) run one test,

   b) get more traces,

   c) know where are the logs.

Any information or pointer to some test doc would help.

With cmake 3.2.3 , Séna is able to build MariaDB.
However, with version 3.11.1 , we have issues (core or hang of cmake, and other 
issues). Investigating.
We'll move to 3.11.3 asap in order to see if we face the same issues.

We use C++11 std::thread.  It requires GCC's -pthread flag on AIX,
and that flag changes the standard library that is used.

OK. Interesting. That looks the same we have here:  pthread/libstdc++.a  .
GCC on AIX is built in 4 flavors (default is 32bit, pthread, ppc64, and 
ppc64/pthread). However, I never saw any package built on AIX using pthread or 
ppc64/pthread ...
And that is an issue since we use /opt/freeware/lib or /opt/freeware/lib64 and 
NEVER pthread...
We have to understand why cmake is different.

Thanks !  I saw it is paged, but I missed the AIX cases.
I've had a look at: https://open.cdash.org/buildSummary.php?buildid=5415006 . 
However, the traces are only high-level information. On our side, we are adding 
traces in order to see the details for figuring out what is really done.

We have to investigate more. Both cmake build and how/why cmake fails with 
mariadb.

Thanks!

Re: [cmake-developers] cmake on AIX

2018-06-12 Thread REIX, Tony 
Hi Brad,

GCC : 6.1 and 7.2 on your side, and 6.3.0 on our side. That should be ok.
Did you build GCC on AIX by yourself or did you take it on some repository, 
like BullFreeware?

Did you use cmake built on AIX for building a project with it? cmake tests are 
98% OK here though that does not work with mariaDB.

Thanks for the idea with static C++ runtime library ! We'll experiment with it 
asap.

Would you mind run the commands:
   dump -Hv cmake
   ldd cmake
on the cmake command that you build, so that we can see which LIBPATH is set 
into the executable.

Or, is there a way to get the traces of the build of cmake?
Did you build it by hand or with a script or a .spec file or anything that we 
could look at?

Looking at your build farm: 
https://open.cdash.org/index.php?project=CMake=2018-06-12 , I see no AIX 
machine.

GCC 7.2.  We previously tested with 6.1 and that worked too.

Try switching to a static C++ runtime library:

  ./bootstrap -- -DCMAKE_EXE_LINKER_FLAGS='-static-libstdc++ -static-libgcc 
-Wl,-bbigtoc'

Re: [cmake-developers] cmake on AIX

2018-06-11 Thread REIX, Tony 
Hi Brad,

Good news ! Thanks for the information.

We are building cmake now only with GCC (6.3.0 for now) on AIX 6.1 .
Which GCC compiler version are you using on AIX ?

We have been able to build the RPMs files of cmake 3.11.1 once by means of our 
RPM cmakespec file.
Now, when we try to rebuild it, we face either a core or a hang in the 
bootstrap phase.
We build cmake in 32bit.
And, when building cmake RPMs succeeded, we had:  98% tests passed, 8 tests 
failed out of 462 .

About the _ZTINSt6thread6_StateE issue, we have figured out what's happening.
It appears that the cmake executable has been built so that it looks for: 
libstdc++.a(libstdc++.so.6) in 
/opt/freeware/lib/gcc/powerpc-ibm-aix6.1.0.0/6.3.0/pthread:/opt/freeware/lib/pthread/
 first, before the base /opt/freeware/lib. However, when we use it for building 
mariadb, we have to set the LIBPATH to: /opt/freeware/lib64:/usr/lib and since 
the symbol _ZTINSt6thread6_StateE belongs to the pthread version of libstdc++.a 
and not to the standard 32bit version of libstdc++.a , that fails .

# nm /opt/freeware/lib/gcc/powerpc-ibm-aix6.1.0.0/6.3.0/libstdc++.a | grep 
_ZTINSt6thread6_StateE
# 
# nm /opt/freeware/lib/gcc/powerpc-ibm-aix6.1.0.0/6.3.0/pthread/libstdc++.a | 
grep _ZTINSt6thread6_StateE
_ZTINSt6thread6_StateE D   536897504
_ZTINSt6thread6_StateE d   536897504   8

# dump -Hv /tmp/opt/freeware/bin/cmake
INDEX  PATH  BASEMEMBER 
0  
/opt/freeware/lib/gcc/powerpc-ibm-aix6.1.0.0/6.3.0/pthread:/opt/freeware/lib/pthread:/opt/freeware/lib/gcc/powerpc-ibm-aix6.1.0.0/6.3.0:/opt/freeware/lib:/usr/lib:/lib

1libperfstat.a   shr.o  
2libstdc++.a libstdc++.so.6 


Moreover, though we try to build mariadb in 64bit, we see that library paths 
and other options used for building mariadbare set to 32bit. And some options 
to be used only in 32bit (-bmaxdata) appears in 64bit. And some dangerous 
options (-brtl and -bexpall) are used.

We have found some   Modules/Platform/AIX-*.cmake  files that seem to control 
how cmake is configured on AIX.
We are cmake beginners and need to learn about how cmake is built and used.

So, either our mariadb .spec file contains mistakes, or the port of cmake we've 
done, though tests are 98% OK, is not yet usable/perfect on AIX.
Have you used cmake on AIX for building any package?
Do you have traces of the build of cmake in your AIX environment?

About adding one of our machines for building cmake to your buildfarm, we'll 
have look later.

Thanks !

Yes, it has long worked on AIX.  We have nightly testing
on AIX 7.2 with both GCC 7.2 and XL 13.1.  A couple of tests
are disabled for those builds but it works in general.

Since CMake 3.10 we require C++11 language and standard
library features so we've only gotten it compiling on AIX
using GCC.  The above-mentioned nightly builds still run
the test suite against XL too though.

If you're interested in running nightly testing too, more
machines/versions would be helpful.  See here:

  https://gitlab.kitware.com/cmake/cmake/blob/master/Help/dev/testing.rst

You'd need to start with a GCC build.  Then I can help you
configure it to run the test suite with XL too.

How did you build or install it?

That symbol demangles to "typeinfo for std::thread::_State",
which is part of the C++ standard library.

Make sure the `libstdc++` library used at runtime is at
least as new as the one used when it was compiled.

[cmake-developers] cmake on AIX

2018-06-08 Thread REIX, Tony 
Hi,

We'd like to know if cmake has already been ported on AIX.

We have tried to port it on AIX, and tests are neary OK:
  3.11.1 : 98% tests passed, 8 tests failed out of 462
  3.9.1 : 96% tests passed, 19 tests failed out of 441

However, when using it for building MariaDB 10.3.1 on AIX, we have hangs or: -- 
Configuring incomplete, errors occurred! or an error talking about rtld.

And, if we use older cmake 3.2.3, we have other issues... and MariaDB requires 
cmake >= 3.7 .

Version 3.11.1 :
 # /opt/freeware/bin/cmake
