Hello,  
i try to build catalyst in apptainer container ubuntu 24.04LTS. I have these errors during the ctest:  
./Source/CTest/cmCTestRunTest.cxx:272 CMake Error at /opt/catalyst/tests/abi\_tests/nm.cmake:90 (message):  
Unexpected symbols found:  
\_\_catalyst\_conduit\_MOD\_\_\_copy\_\_\_iso\_c\_binding\_C\_ptr,  
\_\_catalyst\_conduit\_MOD\_\_\_def\_init\_\_\_iso\_c\_binding\_C\_ptr,  
\_\_catalyst\_conduit\_MOD\_\_\_vtab\_\_\_iso\_c\_binding\_C\_ptr

I don’t understand why…If i remove wrap fortran it works. Other thing to know, i’m using the gfortran compiler of the distrib.

If i do the same thing but not in a container, with distrib Ubuntu 20.04LTS (older than the container one) , gfortran 9.4.0, it works, so i wonder if there’s may be something missing in my container, but howto find what ?  
Thank s for your help  
Regards

These symbols seem to be related to the module stuff. I suspect that there are new symbols showing up that aren’t affected by `-fvisibility=hidden` that we need to take into account.

Can you please file [an issue](https://gitlab.kitware.com/paraview/catalyst/-/issues) about this with the compiler vendor and version you’re using?

I see mentions of these symbols in GCC’s codebase; not sure what changed to make them suddenly show up.
