Dear Dealiiers,

Unfortunately can't install Dealii 9.6.0 with Spack 1.0.0 dev0 using oneapi.2024.1.0 compiler. The only component that fails is llvm. Seemingly, libxml2 header files can't be found. My OS is SLES 15.6 having glibc 2.38

The spack command used:

spack install dea...@9.6.0 +mpi +petsc +trilinos +p4est +gmsh +kokkos ~taskflow %one...@2024.1.0

The error I get:

1 error found in build log:
563 -- Performing Test HAVE_POSIX_REGEX
564 -- Performing Test HAVE_POSIX_REGEX -- success
565 -- Performing Test HAVE_STEADY_CLOCK
566 -- Performing Test HAVE_STEADY_CLOCK

574 in its INTERFACE_INCLUDE_DIRECTORIES. Possible reasons include:

The installation of software via gcc 13.2 was successful, even though installing all components from source made the building extremely slow. I try the installation on the login node and $HOME directory HPC cluster.

Please let me know if I should provide further info.

Thanks in advance,

Elmira

Dear Elmira,

This is an issue with LLVM, not with deal.II. We have no control on that. Maybe you should ask their mailing list for support? Or, alternatively, try figuring out who is including LLVM, and disable that dependency (if you don’t need it).

Dear Luca,

Thanks for the reply, LLVM issue is solved using oneapi.2025.0.4 compiler, however there are some other errors while installation of dealii via spack. I debug one by one, those related to deal.ii I will report with possible solutions. I provide Deal.II for Leibniz Computing Centre as a module.
