• Chris Chambreau (LLNL)

• Mike Collette (LLNL)

Agenda

1. Spack news:

• Variants and optional dependencies are almost done.
• YAML configuration files are almost done.
• Once this is done profiles will be possible, and I can make compiler flags less tedious.

2. Contributions

• Cyrus Harrison (LLNL) contributed uncrustify and cppcheck packages.
• spack diy command merged into develop.
• XL support from Francois Bissey merged into develop.

2. General questions and discussion

• Mike Collette:

  • need ability not just to set compiler flags, but to add compiler flags.

  • need a way to encode what the thread flags are for particular compilers

    • need a way to enforce consistency (don't link intel +threads with gcc +threads)
    • common compiler variant names?

  • conflict error message doesn't tell you which package has the problematic constraint.
