You make zero mention of makepkg or any external build tool in that environment. I'm not sure how you expect anyone to pick up your veil and dispute your method of compilation. Quite frankly, this is rude of you, regardless of whether or not makepkg is at fault. Please take this kind of musdlinging somewhere else, IRC, 4chan, a muddy beach, or whatever.
My final try at proving my point is the following script: it takes a logfile from makepkg -L (with my patch applied), and an optional makepkg.conf file (defaulting to /etc/makepkg), then generates a script containing selected environment variables from the configfile, followed by a replay of all commands executed during the build or package phase (determined by the name of the logfile. Script is self-documenting, but here is the gist of how to use it for TL;DR: - Build package using patched `makepkg -L` - Run makereplay on the generated logfile - Clean out src and pkg directories - Run `makepkg -o` - Change to the top of the extracted source tree - Run `clean-build` and `clean-package` as per the docs inside. <<Here is where the fun begins>> - Now you can do a diff between the log generated by `makepkg -L` and from running the clean-* scripts. - If the build failure occurs with the clean build also, simply submit the logs and clean-* scripts upstream along with your bug report and any needed patches used in the build. - ??? - Profit!! And I mean it, for great justice or whatever. Feel free to use this stuff to track down your core package breakage, feel free even to include it in some toolbox, as long as this pissing contest stops here, i'm allergic to flamethrowers.
