[aur-general] keep debugging symbols in AUR package

Hi all, I use to install AUR package fotoxx. I get some zappcrash message when closing the application an would like to help the author finding the bug. The author sent adapted source packages to get more debugging information. I tried change the PKGBUILD's "pkgrel"- variable to generate several packages containing debugging symbols, but at the end of the build this message looks suspicous: .. -> Stripping unneeded symbols from binaries and libraries... .. What makes packages keep debugging symbols? Tips? Keywords for wiki search? Any hints welcome :o)) -- Friedrich
