'armpl' error when installing gcc with spack [solved]

[Ester Comellas]

Hi All,

I'm in the process of installing the latest dealii version via spack on a macOS Monterey v12.4, following the instructions given in the dealii github website: https://github.com/dealii/dealii/wiki/deal.II-in-Spack. 

I encountered the following error when I do "spack install gcc":

==> Error: Package 'armpl' not found.

Following the suggestions here solved the problem: https://github.com/spack/spack/issues/31453

So, basically, type:

    spack clean -ab

         spack clean -fmps

And then try again:

        spack install gcc

Hope this post will be helpful to anyone who encounters a similar problem in the future.

Best,

Ester
