Trying tu upgrade after a sync, p7zip-2.4.20-r1 to 2.4.27 I have an error about "reloaction" and "fPIC". As suggested in the error message, I add -fPIC to my CFLAGS and p7zip builds. Reproducible: Always Steps to Reproduce: 1.Sync 2.Update p7zip from 4.20-r1 to 4.27 3.

No wonder. p7zip-4.27.ebuild does this: sed -i \ -e "/^CXX=/s:g++:$(tc-getCXX):" \ -e "/^CC=/s:gcc:$(tc-getCC):" \ -e "s:-O1 -s -fPIC:${CXXFLAGS}:" \ makefile* || die "cleaning up makefiles" Of course if you'll strip -fPIC from CFLAGS it'll barf on AMD64!
Hi, I can confirm that! We need a fix!
removing the -fPIC from the sed statement obviously did the trick, thanks for the hint :)
