Agenda

(This will be just Q&A - there are no pre-planned general Spack discussion items)

• Stephen: the buildable flag WRT binary cache
  • See Nov 30th notes: https://github.com/spack/spack/wiki/Telcon%3A-2022-11-30
  • Richarda: has it in her queue
• Valerio: issue with gcc package in an environment
  • It wasn't defining CC etc.
  • See: https://github.com/spack/spack/issues/34791
  • Peter: has it in his queue
  • For internal discussion: do we want to enable setting CC/CXX/etc.
  • Todd/Valerio: it would be useful to have a shell section in an environment that allows us to define shell variables like CC etc. (this would in particular be useful if an env has both gcc and intel, in which case there would be a conflict)
• Valerio: use case
  • Developing a package; using a spack environment to build all the dependencies
  • Peter: FWIW Spack adds a few extra features if you happen to develop the root package in Spack, but we want to support the case where you build just the dependencies with Spack too
• Dom: errors with RPATHing when creating build caches
  • Specifically on Mac
  • 34375: duplicate RPATH errors on Mac OS
  • 32478: containers
  • (Coordinating with Massimiliano)
• Justin: interest in using NERSC resources for CI?
  • Todd: like gitlab CI runners?
    • Justin: perhaps not that
  • Todd: like nightly CI runs
