[SATURNE-9.1.0] Compilation with MEDCoupling 9.15.0

Posted: Tue Mar 03, 2026 10:33 am
by Goaty
Hello! :D

The users of the cluster I administer need to have version 9.1.0 of Saturn with MEDCoupling.
MEDCoupling was not installed long ago, so I am only referring to the following documentation to try to get everything working: https://github.com/SalomePlatform/medcoupling & https://github.com/code-saturne/code_sa ... INSTALL.md

I am using RedHat 8.8 on x86_64, with the system's GNU compilers (8.5.0) and the following modules:

Code: Select all

(py310_condaforge) [toto@cluster-node107 build]$ module li
Currently Loaded Modulefiles:
 1) cmake/3.29.3   2) conda3   3) ucx/1.15.0   4) openmpi/4.0.3(default)
(py310_condaforge) [toto@cluster-node107 build]$ python --version
Python 3.10.4
After installing the CGNS, HDF5, MED, and SCOTCH prerequisites via the “install_saturne.py” script provided by Saturne, here are the arguments passed to “configure” for the installation of MEDCoupling that I have included (Here: “https://github.com/code-saturne/code_sa ... INSTALL.md”):

CMake Deprecation Warning at CMakeLists.txt:21 (cmake_minimum_required):
  Compatibility with CMake < 3.5 will be removed from a future version of
  CMake.

  Update the VERSION argument <min> value or use a ...<max> suffix to tell
  CMake that the project does not need compatibility with older versions.

I tried recompiling version 5.0.0 of MED with “--enable-api23” and then MEDCoupling with “-DCMAKE_CXX_FLAGS=”-DMED_API_23," but nothing worked.

Have you ever encountered this error?
Which version of MED is recommended for which version of MEDCoupling for use with Saturn 9.1.0?

Furthermore, I see that in Saturn's “configure,” the MEDCoupling feature appears to be forcibly disabled, according to lines 12389 and 12390:

Code: Select all

 (py310_condaforge) [toto@cluster-node107 build]$ cat -b ../../saturne/code_saturne-9.1.0/configure |grep -i "cs_have_medcoupling="
 12389  cs_have_medcoupling=no
 12390  cs_have_medcoupling_loader=no
Is this a hidden message to tell us to not use MEDCoupling ?

Don't hesitate to tell me if you need more informations :)

Hello,

The lines in the "configure" are just initializations before the test.

We have had issues with MEDCoupling link on one machine running RHEL 8.8 after a system upgrade due to C++ API achanges, but recompiling both MEDCoupling and code_saturne avoids the problem. An alternative was to add the following code_saturne "configure" options helped:

Code: Select all

CFLAGS_ADD="CFLAGS=--gcc-toolchain=/usr"
CXXFLAGS_ADD="CXXFLAGS=--gcc-toolchain=/usr"
but you error here seems different.

For MED, on that machine, we use

Code: Select all

${MED_SRC}/configure --prefix=${MED_PREFIX} --with-hdf5=${HDF5_PREFIX} --with-med-int=long --disable-fortran --disable-python --disable-static && make && make install && make clean
For MEDCoupling

Code: Select all

${CMAKE} -DCMAKE_INSTALL_PREFIX=$MEDCOUPLING_PREFIX \
-DCONFIGURATION_ROOT_DIR=$MEDCOUPLING_SRC/../configuration-${MEDCOUPLING_VERSION} \
-DMEDCOUPLING_BUILD_DOC=OFF \
-DMEDCOUPLING_BUILD_TESTS=OFF \
-DMEDCOUPLING_ENABLE_PARTITIONER=OFF \
-DMEDCOUPLING_ENABLE_RENUMBER=OFF \
-DMEDCOUPLING_USE_MPI=ON \
-DMEDFILE_ROOT_DIR=$MED_PREFIX \
-DHDF5_ROOT_DIR=$HDF5_PREFIX \
-DHDF5_INCLUDE_DIR=$HDF5_PREFIX/include \
$MEDCOUPLING_SRC
make && make install && make clean
Using MED 5.0.0 and MEDCoupling 9.14.0.

I have not tested with MEDCoupling 9.15 yes, so there might be a compatiility issue is some Enum or type changed. I'll test that locally to see if we need to update the code for compatibility on our side. In the meantime, MEDCoupling 9.14 should work.

Also note that for clusters, I do not use the "install_saturne.py", or at least not just that installer: it can be useful for a basic setup, then yoy can go into the code_saturne build directory, check the configure commend used at the top of the "config.log" file, and re-run configure with additional options.

Additionally, though code_saturne detects environment modules (such as those defined with lmod) automatically, and "saves" the settings to reload the same modules upon execution, if does not specifically handle Conda, so checking the build and usage environments are the same has to be managed on your side. That can be an issue when using the code, but not while building it though.

Best regards,

Yvan
