Discussion

• Recently-merged PRs
  • Better handling of packages without URLs: https://github.com/spack/spack/pull/8967
  • Use recommended mirror download site for GNU packages: https://github.com/spack/spack/pull/8992
  • install_tree function (provided to users writing packages) can now install into an existing directory structure: https://github.com/spack/spack/pull/8289
  • Update spack arch command to support --operating-system and --target-flags: https://github.com/spack/spack/pull/8879
  • Updates to cc flag ordering: https://github.com/spack/spack/pull/8889 (addressing issues with https://github.com/spack/spack/pull/4692)
  • Added blis package: https://github.com/spack/spack/pull/8925
  • Added support for the Meson build system: https://github.com/spack/spack/pull/8467
• (TBD - solicited)
  • SpackDev and its requirements on Spack.
    • Allows a user to develop several packages simultaneously, based on maintaining a CMakeLists.txt (treats the set of development packages as external from CMake's perspective)
    • How does this compare to:
      • spack setup (and proposed extensions based on Spack environment support: https://github.com/spack/spack/pull/8231)
      • spack diy
    • Could use some updates to Spack's core:
      • Improve dump-environment function (make it "source"-able)
      • Update Package to allow outputting CMake variables for the package without installing it
      • Very long command lines to customize variants for install
        • spack install --dag
        • This seems similar to packages.yaml
  • Intel packages PR: https://github.com/spack/spack/pull/7469
    • Ready for review/merging
    • There are spots where Intel assumptions conflict with Spack assumptions, e.g.
      • https://github.com/spack/spack/issues/8632
      • MPI runtime vs. MPI development packages
  • Bot to automatically close issues: https://github.com/spack/spack/pull/8811
