Agenda

Q&A

• Davide: have a spec list (including matrix) in an env; comment out one spec and many extra things are concretized
  • Also, requesting installation of a generic gcc package, and getting an older version of gcc@9.5.0
  • When installing octave, a pre-installed (i.e. installed earlier by Spack) newer version of gcc is picked (@13) but when removing the octave spec an older (and not-yet-installed) gcc is picked
  • Suggestion: try with reuse off
  • Suggestion: try forcing versions
• Davide: desire to diff the output of environment concretization (why did env instance x concretize foo and env instance y concretize foo'? how do they differ exactly?)
  • Peter: should spack find -C in an env be able to dump to a spec.yaml file (once that happens, spack diff could diff them)
• Davide: build a package in spack, get a failure, then use spack build-env to get to the build environment of that package, re-execute the failing command, it succeeds
  • Sanity check, if the installation was parallel, the error messages may be ordered strangely and the actual failing command may be unclear; you can do spack install -j1
• Vivek: do we have any tentative date for the 0.20.2 release?
