Ok, so I thought it was all well and good, but now a bug report made me realise that gcc < 3.4 doesn't have -fpie/-fno-pie. Here's the problem: 1) valgrind has some features that only work with -fpie 2) valgrind's tests fail to build with -fpie 3) because of the hardened gcc profile, valgrind's tests need -fno-pie 4) simply patching some makefiles to add -fno-pie for tests is not possible because gcc < 3.4 doesn't support -fno-pie 5) having the valgrind developers modify their configure/makefiles to add -fno-pie for tests in case gcc supports it is not enough, because user CFLAGS are appended and CFLAGS in make.conf may contain -fpie 6) using filter-flags to get rid of -fpie in user's CFLAGS actually adds -fno-pie and disables features referred to in 1) What do I do now? Why is -fno-pie being added by filter-flags anyway? Maurice. -- Maurice van der Pot Gentoo Linux Developer [EMAIL PROTECTED] http://www.gentoo.org Creator of BiteMe!
