@jrohwer

When building PETSc (more specifically, petsc4py), one test (ex100 from ksp) will fail if a previous (major) version is installed. I could not figure out why this happens. The solution would be to build in a clean root (which is a little bit complicated due to dependency on other AUR packages) or simply uninstall the old version before.

Any help to solve this issue is welcomed.

@ilovekiruna: Did you recompile PETSc?

It looks like the latest package still depends on libsuperlu in version 6. However, in the extra repo, the latest package is version 7. Therefore an ldd on libpetsc ldd /opt/petsc/linux-c-opt/lib/libpetsc.so.3.22 gives libsuperlu.so.6 => not found.

@MartinDiehl Could you send me your /etc/makepkg.conf file in the email? Because even after the update the same problem happens again and I need the same fix. Maybe it is related to this file in my computer.

@medaminezghal

thanks. Good to see that you fixed it. I can't reproduce the error here and will try on other setups later.

@MartinDiehl I found a fix


  ./configure --prefix=${_install_dir} ${CONFOPTS} \
              "CFLAGS=$CFLAGS" \
              "CXXFLAGS=$CXXFLAGS" \
              "FFLAGS=$FFLAGS" \
              "LDFLAGS=$LDFLAGS -lstdc++" \
              "MAKEFLAGS=$MAKEFLAGS"

Just add the -lstdc++ to the LDFLAGS

@MartinDiehl I’ve already done the rebuild for all packages in my system to python 3.13 but this module has an issue when I import it. I found it by accident when I try to install donfinx. For that, I tried to test an example using the library in python and found this error.

@medaminezghal: maybe you need to rebuild for Python 3.13

when I try to import the library I get this error:

The build with trilinos-ml fails because Trilinos 16 has deprecated the ML package:

In file included from /usr/include/ml_include.h:16,

...

These warnings are printed to stderr by the compiler and the Petsc build system treats it as an error when it checks if the #include <ml_include.h> include statement works.

@carlosal1015: I assume you solved it, at least I saw in your Kokkos package '' -DKokkos_ENABLE_OPENMP=OFF''

We could also try to enable openMP in PETSc, but I think that is normally not recommended.
