Ahhh, right, thanks. My current hack would not work as expected if I switch to another project and compile that without first killing the previous *compilation* buffer, since it would have the previous project settings. So to be project aware I guess I would somehow need to set the compilation-search-path from compilation-start-hook?
Why cannot you have all the possible directories in the list?
Do you mean all directories for the current project, or all directories across all projects? If the former, that's exactly what I want. If the latter, that seems prone to incorrectly resolving the source file for a message as coming from a project other than the current (particularly for generic filenames like "utils.c") and additionally I try not to have anything project specific in my global emacs init, they should live in the project repo (and .dir-locals.el is the only mechanism I'm aware of for that).
Cheers,
Len.
