PETSc fails to build with ML

[dajuno]

Hello.

I'm trying to build fenics which uses petsc with ML. However, the petsc compilation fails on my system (ArchLinux) during the compilation of ML, which is downloaded from https://bitbucket.org/petsc/pkg-ml.git. Compiling without ML works.

I stripped down the yaml file to build petsc with ML alone, the same error occurs:

extends:
- file: arch.yaml
packages:
  mpi:
    use: mpich
  blas:
    use: openblas
  petsc:
    version: '3.6.1'
    download: ml
    coptflags: -O2
    link: shared
    debug: false

(blas and mpi were required)

Here is the build.log.

Best, David

This looks like the same problem. I didn't know that the ML build system is using Perl. Maybe you can try to build PETSc with Perl? Like this:

  ...
  petsc:
    build_with: |
      perl
    ...

That did it!
Thanks
