despite this I'm getting a lot of build errors similar to this:

In file included from /home/s-ol/.cache/paru/clone/python-ocp/src/OCP/OCP/AdvApp2Var_pre.cpp:114:
/home/s-ol/.cache/paru/clone/python-ocp/src/OCP/OCP/NCollection_tmpl.hxx:866:85: error: expected unqualified-id before ‘>’ token
  866 | template <typename TheKeyType,typename Hasher=NCollection_DefaultHasher<TheKeyType>>>
      |                                                                                     ^

There's also deprecations etc. For the moment I've downgraded opencascade to 7.8.1-3 and will keep using my python-ocp build from january.

a solution for the MPI::MPI_C error is to add mpi to the COMPONENTS list in OCP's CMakeLists.txt. I imagine this was caused by an update to vtk, but I'm not sure if it is to be resolved in OCP or VTK - for the time being I've opened a PR to the ocp repo.

The fix can be applied by adding the following line below the other changes to CMakeList.txt in prepare():

  sed "/freetype/a    mpi" --in-place CMakeLists.txt  # fix vtk MPI dependency

CMake Error at /usr/lib/cmake/vtk/VTK-targets.cmake:1897 (set_target_properties):

My builds are failing like this too.

Yeah, it takes forever to build. You can speed up the build by increasing _n_parallel_build_jobs but beware doing that might cause the build to fail while linking (at the end) when it runs out of RAM quite late in the job which is really frustrating. I recommend leaving _n_parallel_build_jobs = 1 and starting the build before you go to sleep.

I recall patching out the progress bars because they were making the build logs difficult for me to read.

Sadly not building... :('

CMake Error at /usr/lib/cmake/vtk/VTK-targets.cmake:1897 (set_target_properties):
  The link interface of target "VTK::mpi" contains:

    MPI::MPI_C

  but the target was not found.  Possible reasons include:

    * There is a typo in the target name.
    * A find_package call is missing for an IMPORTED target.
    * An ALIAS target is missing.

Call Stack (most recent call first):
  /usr/lib/cmake/vtk/vtk-config.cmake:147 (include)
  CMakeLists.txt:8 (find_package)

@greyltc is there a reason for disabling the progress bars?

This thing takes HOURS to build, and at least they give an indication of progress. I only now realized the PKGBUILD was applying a patch to disable them.. wtf?

@greyltc Would you mind adding the fmt package to depends?
Without fmt, it builds cleanly but fails at runtime.

@s-ol I got the same error.

Rebuilding the clang15 package with these patches applied fixed it for me.

s-ol commented on 2024-12-27 23:09 (UTC)

Having problems building because of some clang version mismatch:

clang.cindex.LibclangError: /usr/lib/llvm15/lib/libclang.so.15.0.7: undefined symbol: clang_CXXMethod_isDeleted. Please ensure that your python bindings are compatible with your libclang.so version.

greyltc commented on 2024-06-07 16:51 (UTC)

It's probably not stuck, just takes forever to build. Leave it overnight if you think it might be stuck.
