# Cactus configuration for Arch and Arch-based distros

# NOTES:
# - `-Wno-error=incompatible-pointer-types` removes error temporarily, see https://bitbucket.org/einsteintoolkit/tickets/issues/2802/compilation-faiulres-in-twopunctures_bbhsf
# - AEILocalInterp defines `bool` which in `c23` is a keywork, specify C17 standard as a workaround
# - The toolkit raises an error with lastest HDF5 version. Is this a toolkit or Arch errror? Version 1.14.5-1 in repos works

# Packages to install (all available on official repos)
# - gcc
# - gcc-fortran
# - hdf5
# - blas-openblas
# - openmpi
# - gsl
# - hwloc
# - libjpeg-turbo
# - openssl
# - fftw
# - boost
