Error while compiling libMesh on HPC: "unsupported/Eigen/IterativeSolvers: No such file or directory"

[ecclough]

I'm trying to get MOOSE installed on an HPC and I've run into the following error while compiling libMesh using the update_and_rebuild_libmesh script:

  CXX      src/solvers/libmesh_opt_la-eigen_solver.lo
  CXX      src/solvers/libmesh_opt_la-eigen_sparse_linear_solver.lo
  CXX      src/solvers/libmesh_opt_la-eigen_time_solver.lo
../src/solvers/eigen_sparse_linear_solver.C:35:10: fatal error: unsupported/Eigen/IterativeSolvers: No such file or directory
 #include <unsupported/Eigen/IterativeSolvers>
          ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
compilation terminated.

make[1]: *** Waiting for unfinished jobs....
make[1]: Leaving directory '/home/ecclough/projects/moose/libmesh/build'
make: *** [Makefile:33497: all-recursive] Error 1

I successfully built petsc prior to this step using the following:
./scripts/update_and_rebuild_petsc.sh --skip-submodule-update \
--download-cmake=/home/ecclough/projects/packages/cmake-3.28.3.tar.gz \

--download-strumpack=/home/ecclough/projects/packages/STRUMPACK-7.1.4.tar.gz

after which I ran ./update_and_rebuild_libmesh.sh --skip-submodule-update, which throws the above error during compiling. Can someone point me in the right direction to correct this error?

The petsc and libMesh config logs and the libMesh diagnostic log are attached.

config.log
libmesh_diagnostic.log

Hello

There are a couple errors in the config.log. Did the first update_and_rebuild_petsc actually download everything well and completed?
Is there a petsc module on your HPC you could use right now?

Here's a workaround:

• Download eigen3 (version >= 3.1.2) to an external folder
• modify configure script to include --with-eigen-include="external eigen3 directory"

after which libmesh successfully compiles.
