[opensuse-packaging] Using the gold linker
Hi: Is there any way to use the gold linker in a project-wide way and/or per package basis without resorting to export LD=... or gcc -B hacks ? Thanks. -- To unsubscribe, e-mail: opensuse-packaging+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-packaging+help@opensuse.org

ln -fs gold /usr/bin/ld (globally) or export LD=gold (for automake) Though now the question is where to add that when you can't touch /usr/lib/build/build :) -- To unsubscribe, e-mail: opensuse-packaging+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-packaging+help@opensuse.org

Create a package "gold-by-default", which * Requires binutils-gold * creates a new directory /opt/gold/bin * therein a symlink named 'ld' (to /usr/bin/gold) * creates a new file /etc/profile.d/gold-by-default.sh which sets and exports COMPILER_PATH=/opt/gold/bin, and prepends PATH with that path Then you should be able to always install gold-by-default in your project. The important thing is the $COMPILER_PATH setting, so that collect2 (an internal program of gcc which actually calls the linker) finds the new ld. collect2 itself won't look at $LD, or into $PATH. Ciao, Michael.

Thanks for the hint, that is much cleaner, however such package fails to build due to "/opt/gold/ld" is not allowed anymore in FHS 2.2. :-) -- To unsubscribe, e-mail: opensuse-packaging+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-packaging+help@opensuse.org

Or much easier:
RPM_OPT_FLAGS="$RPM_OPT_FLAGS -fuse-linker-plugin"
Well, that works with GCC 4.5 in Factory only.
