Telcon: 2021 08 18

Meeting to be held at 9am PST August 18, 2021

Attendees:

• Todd Gamblin
• Peter Scheibel
• (whoever wants to ask Spack questions or discuss agenda items)

Agenda:

• Spack's compiler wrappers require bash, to support them on systems without bash we are considering either:

  • Making the wrappers posix-sh compliant*
  • Replacing the script-based wrappers with executables (compiled from C)

• Spack compiler flag specification

  • Specifying compiler flags is hard now
  • We have flag_handler methods
  • Should we model specific flags (i.e. those which should be propagated vs. not)

* note from @haampie: we rely on arrays & heredocs, that's tough in sh. @alalazo pointed out we can generate the sh script from a template, and hard-code the case statements instead of using loops and arrays. Might as well generate a C-script then, compile it, and have the lowest overhead compiler wrapper ;) https://github.com/spack/spack/pull/25380#issuecomment-901049740
