Agenda

• Mark: ping on https://github.com/spack/spack/pull/34541
  • Suggested change to user, but they may not have time for it
  • Chris: has a Spack branch that makes consistent the libintl/libiconv
• Leopold: ping on https://github.com/spack/spack/pull/18452
  • Massimiliano: will re-review
• Wileam: ping on https://github.com/spack/spack/pull/27247
  • Harmen or Peter will re-review
• Leopold: cross compilation support?
  • Wileam/Massimiliano: for targeting other microarchitectures, try setting concretizer:host_compatible:true
  • For now: in general it is quite limited
  • Generally requires manual intervention
  • If a single package needs to access both a front and backend compiler, then Spack doesn't track that well
  • For building some packages with one compiler, and other packages with another compiler, you'd have to be very specific with user specs or package requirements
    • Massimiliano: separate concretization of build deps is a pre-req
  • Wileam: relevant slack conversation: https://spackpm.slack.com/archives/C5W7NKZJT/p1675439980802569
  • TODO: add a dedicated section in docs about cross compilation
• Chris: request based on last week's meeting: https://github.com/spack/spack/issues/35372
  • (Install only non-root deps in an environment on request)
