Description Patrick McLean gentoo-dev 2019-05-01 18:54:52 UTC
We could easily catch ebuilds that don't respect CC (and LD and other system programs) by adding shell scripts (or a single script with a bunch of symlinks) to portage's PATH that record when they are called. then exec the "proper" program (like "cc" would 'exec "${CC}"''. If the scripts ever get called during a phase, then we could trigger a QA warning for that phase.

The standard portage install should include wrappers for all common programs that build systems often call that should be overridden.

We could even make a FEATURE (say call it strict-progs) that makes these shell scripts simply "exit 1" so the build will fail if a package doesn't respect one of the program variables. Developers could be encouraged to enable this feature so they catch any ebuilds that aren't respecting variables such as CC.
