And just to add to the mix: Using -fstack-protector twice, because it's in CCFLAGS and LDFLAGS, because we call the compiler and linker seperately sometimes (GNUMakefile vs. ExtUtils::Embed), will cause a gcc crash. So if I fold the compiler and linker flags together with the typical compile+link command, I explicitly have to remove -fstack-protector from LDFLAGS; in B::C cc_harness. $ perl -V:ccflags -V:ldflags ccflags='-DPERL_USE_SAFE_PUTENV -U__STRICT_ANSI__ -g3 -fno-strict-aliasing -pipe -fstack-protector -I/usr/local/include'; ldflags=' -Wl,--enable-auto-import -Wl,--export-all-symbols -Wl,--enable-auto-image-base -fstack-protector -L/usr/local/lib'; -- Reini Urban http://phpwiki.org/ http://murbreak.at/Thread Previous | Thread Next
