Building gcc I get multiple warnings "Package contains references to $srcdir". This affects multiple files. For example in /usr/bin/cpp I find the following reference: /home/me/Builds/gcc/src/gcc/gcc/diagnostic.c
I am pretty sure there is nothing to worry about, some packages just include such information. But I really want to know where this is coming from. In an older mailing list thread I read that debug builds usually have these references. But I set !debug in makepkg.conf and made sure it's not overwritten by the PKGBUILD and I passed the --disable-debug option to gcc's configure script. It feels a bit wrong that a compiled, stripped package has mentions of its source files in it.

What PKGBUILD are you using?
"UNIX is simple and coherent..." - Dennis Ritchie, "GNU's Not UNIX" - Richard Stallman

It's a slightly modified version of the PKGBUILD from the repos, basically removed support for all languages except C and C++.

The repository version has references to $srcdir (Arch's clean chroots use "/build/gcc/src") too, it's unusual, but I wouldn't worry about it.

Good to know there is nothing wrong. However, obviously this references are not guaranteed to be valid all the time. So they are not really useful all the time. Any chances you have an idea what to do to remove them from the package? Or is this something I should discuss upstream?
Offline
Why do you care if they aren't useful? They are useful sometimes, which is why upstream wants them in the first place, you just don't have the information on your system for debugging purposes (and by default probably aren't debugging anyway ).
