Installation issue with spack related to expat/libbsd

installation
1

I’m trying to install fenicsx on an HPC using spack
I followed the github instructions for spack.

module load gcc/13.1.0
module list  # => verif gcc ok

cd /home/$USER/git
git clone https://github.com/spack/spack.git
. ./spack/share/spack/setup-env.sh

spack env create fenicsxenv
spack env activate fenicsxenv

spack add fenics-dolfinx+adios2 py-fenics-dolfinx cflags=-O3 fflags=-O3

spack concretize --force
cat ./spack/var/spack/environments/fenicsxenv/spack.yaml  # verif compilers ok

spack install

Wich always results as

==> Error: ProcessError: Command exited with status 1:

Thank you for your reply !

I followed your link up to this one

Which solved the issue (removing libbsd.so in the spack directories and linking libbsd.so toward libbsd.so.X.Y.Z instead)
