ERROR: net-www/mozilla-1.7 failed. !!! Function src_compile, Line 370, Exitcode 2 !!! (no error message) Reproducible: Always Steps to Reproduce: 1. CXXFLAGS=-fno-default-inline emerge mozilla Actual Results: Linker failer of the description Expected Results: Linked application. filter the flag -fno-default-inline, build works fine then.
Created attachment 36223 [details, diff] mozilla-1.7.ebuild.diff Patch to filter the flag -fno-default-inline
The problem here is that flag-o-matic's strip-flags function is broken: if [ "${flag%%${y}}" = "" ] || [ "${flag:0:5}" = "-fno-" ] || [ "${flag:0:5}" = "-mno-" ] ; then NEW_CFLAGS="${NEW_CFLAGS} ${x}" Anything that starts with -fno- or -mno- is allowed into NEW_CFLAGS at the moment. :-|
Fixed now in flag-o-matic, thanks to Spanky. You will need to emerge --sync
