1. octave Spack package

   • Review:
     • General issue with packages that include the compiler path in binary
     • Python solves this with its filter_compilers method
       • We could mimic this in other packages
     • Paul Hopkins wonders whether this could be solved by creating a wrapper that includes all of the spack env variables necessary to run, so that they can be run externally without failing.
   • Proposal: change the spack compiler wrapper so that it passes through to the underlying compiler if called from outside of Spack.
   • Jim Amundson may already be doing something like this
   • spack env may provide a solution as well

2. Binary caching

   • CODECOV IS GREEN!
   • resubmitted in #4854

3. NERSC using Spack in production on Edison

   • Not using modulefile generation
   • Consultants annoyed by spack rebuilds
     • New concretizer will mitigate this
     • Separate build dep concretization may provide a jump-off point to address this sooner
     • Jim Amundson is working on something that would automagically create external entries for system packages
   • shared vs static builds on Cray
   • single-user vs shared-user challenges

4. cflags bug from the slack channel

   • Fix is on the way

5. External packages

   • Adding variants explicitly to external packages
   • Mario will test suggestions from previous thread (issue #4913)
