Verify Quick Start with Spack #302

Open adammoody opened 3 years ago

adammoody commented 3 years ago

Following the Spack path on the Quick Start page from start to finish as a new user would, verify that all steps work as described. (Be sure to remove any existing ~/.spack and clone from scratch to emulate behavior of a new user). Fix problems where needed.

I'll double check on this.

adammoody commented 3 years ago

Yes, the instructions for a spack build do work, at least for a build of test_api. It's a bit convoluted to test. It requires one to use the Spack SCR PR (https://github.com/spack/spack/pull/22916) to build. Then you have to hack the examples/makefile to avoid building test_interpose, since that's since been removed.

Actually, on closer look, that uncovered a problem in the examples/makefile.in where it was still trying to build the interpose examples even though the source for those are not installed with CMake anymore. I pushed a commit to drop those from the makefile.
