I am using Emacs 23 and have the following problem:
I run our project's build system from within Emacs like M-x compile -> cd /foo/bar && ./build
The build system now does some magic, "cd"s into some subdirectory for the build process and then gcc throws an error:
../src/somesource.cc:50 error: blablabla
Now the problem is that Emacs won't find that path, because it assumes the compile process started out in /foo/bar, and not in /foo/bar/builddir. So the leading "../" is not working for Emacs, e.g. when running compile-goto-error. Is there a way to tell Emacs to try skipping leading "../"?
The best solution might be to change the build system to emit messages when it changes directories. Emacs looks for
Entering directory `...'
...
Leaving directory `...'
(See the compilation-directory-matcher variable. If your build system does emit messages when it changes directories, but they're not in the format Emacs is looking for, you can add new regexps to compilation-directory-matcher.)
The other solution is to change compilation-search-path (which is a list of directories).
