Package: src:adios2 Version: 2.12.1+dfsg1-2 User: [email protected] Usertags: python3.15 Tags: patch, ftbfs, forky, sid Severity: serious
Hi! While rebuilding the python related packages against the Python 3.15rc2 version I ran into the adios4dolfinx FTBFS [1], which is reported in #1145118. After looking into this, I found that the problem is due to the fact that with HDF5 version 2, we need to pass an extra flag to enable parallel (HDF5_PREFER_PARALLEL). So, I've added that in debian/rules, for the MPI variant. Additionally, the HDF5_ROOT:PATH variable is different when using the serial variant or the MPI variant, and the FindHDF5 CMake module doesn't find it, so I've also added those settings to debian/rules. I've applied these changes in the sandbox [2] to verify that adios2 builds successfully, and then rebuilt adios4dolfinx against it, which also built successfully. Setting the severity as serious, as this misconfiguration triggers a FTBFS in a different package.
