FenicsX installation in cluster using spack

installation
1

Hello,

Following my post on parallelization, I am trying to reinstall FenicsX in the cluster using spack. I enter the following command lines:

git clone https://github.com/spack/spack.git
. ./spack/share/spack/setup-env.sh
spack env create fenicsx-env
spack env activate fenicsx-env
spack add py-fenics-dolfinx cflags="-O3" fflags="-O3"
spack install

And I get the following error:

  1. Cannot select a single “version” for package “py-petsc4py”
  2. Cannot select a single “version” for package “py-fenics-dolfinx”
  3. No valid value for variant ‘libxml2’ of package ‘python’

Do you have any suggestions on how to solve this issue?

Thank you !

I also tried the solutions suggested here: Error: fenics-dolfinx requires GCC-9 or newer for improved C++17 support but gcc version 10.2.1 in my system - #5 by jiangzhangze. I created a new spack environment and added the command lines:

spack compiler find
spack add py-fenics-dolfinx%gcc cflags="-O3" fflags="-O3"
spack install

and now I get the following errors:

==> Error: concretization failed for the following reasons:

   1. fenics-dolfinx: fenics-dolfinx requires GCC-9 or newer for improved C++17 support
   2. fenics-dolfinx: fenics-dolfinx requires GCC-9 or newer for improved C++17 support

What compilers do you have installed on your cluster?

What does

module avail gcc

yeild?

You should load an appropriate version of gcc using module load
