Agenda

  • Improve error messages related to concretizing large DAGs that are over-constrained
    • Peter: I think a heuristic approach would be useful: when you get something like "can't pick version 4.1 and 5.2", look for all the packages in the dag which enforce constraints related to that
    • Greg/Todd: use xclingo to extract a description of the constraints
  • Justin Cook
    • https://github.com/spack/spack/issues/32451
      • A package got removed which lead to an obscure error with find_headers (empty list for a nonexistent directory)
      • Error message should probably say: "this directory no-longer exists"
      • Is there some sort of command that could look through all the packages that are thought to be installed, and determine if they were removed?
