Catch2 Issue (solved) and HDF5 MPI Question

[summer7807]

Hi guys：
I encountered the following error when installing openpmd on my terminal (Ubuntu 22.04). I don't know what the problem is. Can you give me some advice or guidance? Thank you.

Hey,
for the HDF5 error: If you build HDF5 manually, you have to actively enable parallel HDF5. I usually build the CMake version of HDF5 (https://support.hdfgroup.org/ftp/HDF5/releases/hdf5-1.12/hdf5-1.12.2/src/CMake-hdf5-1.12.2.tar.gz) and then put the CMake options -DHDF5_BUILD_CPP_LIB=OFF -DHDF5_ENABLE_PARALLEL=ON -DHDF5_BUILD_EXAMPLES=OFF -DBUILD_TESTING=OFF. (the CPP_LIB parameter is necessary). If you installed HDF5 any other way, make sure that it is parallel HDF5.

The second one seems to be this error: catchorg/Catch2#2421. We should update our internal version of Catch2 for fixing it. You can deactivate test builds by -DopenPMD_BUILD_TESTING=OFF, or alternatively if you want to build tests, install a recent version of Catch2 and then set -DopenPMD_USE_INTERNAL_CATCH=OFF.

Hi @franzpoeschel
I tried to install parallel "HDF5" and successfully installed it. But I ran make -j $(nproc) install and reported the following error. I haven't updated the version of "CATCH2". Ran -dopenpmd_build_testing=off, I don't know whether this is feasible

The Catch2 issue should be fixed in dev now since #1299 was merged. Thus, you can build again with testing if you like (and temporarily disabling tests was the right call for the issue).

Your HDF5 issue still looks like the HDF5 that is included was not compiled with MPI (aka HDF5 parallel) support enabled. The missing functions are essential HDF5-MPI routines.
Can you share with us the exact command line calls you run to install HDF5 and to make it know to openPMD-api's configuration step?
