[gentoo-user] gcc 4.2.4 fails to build
Hello, I need to build gcc 4.2 on a core 2 duo system. The only 4.2.x version is 4.2.4, which is masked by ~. When I try to build it fails: ... /var/tmp/portage/sys-devel/gcc-4.2.4-r1/work/build/./gcc/xgcc -B/var/tmp/portage/sys-devel/gcc-4.2.4-r1/work/build/./gcc/ -B/usr/x86_64-pc-linux-gnu/bin/ -B/usr/x86_64-pc-linux-gnu/lib/ -isystem /usr/x86_64-pc-linux-gnu/include -isystem /usr/x86_64-pc-linux-gnu/sys-include -O2 -O2 -O2 -march=core2 -pipe -DIN_GCC-W -Wall -Wwrite-strings -Wstrict-prototypes -Wmissing-prototypes -Wold-style-definition -isystem ./include -fPIC -g -DHAVE_GTHR_DEFAULT -DIN_LIBGCC2 -D__GCC_FLOAT_NOT_NEEDED -msse -c \ /var/tmp/portage/sys-devel/gcc-4.2.4-r1/work/gcc-4.2.4/gcc/config/i386/crtfastmath.c \ -o crtfastmath.o /var/tmp/portage/sys-devel/gcc-4.2.4-r1/work/gcc-4.2.4/gcc/config/i386/crtfastmath.c:1: error: bad value (core2) for -march= switch /var/tmp/portage/sys-devel/gcc-4.2.4-r1/work/gcc-4.2.4/gcc/config/i386/crtfastmath.c:1: error: bad value (core2) for -mtune= switch I do indeed have -march=core2 in /etc/make.conf. I suppose I could change -march= to something else and try again - but what should I change it to? gcc-4.2.4 would only be used for non-portage compiling so, am I right in thinking that after it is built it would be safe to revert to -march=core2? Thanks, Roger

if you're using an intel core2 processor, the proper -march setting is -march=nocona On Tue, 01 Dec 2009 14:26:28 +0100, Roger Mason rma...@mun.ca wrote: Hello, I need to build gcc 4.2 on a core 2 duo system.

You can try march=native. Maybe it is a good choice for make.conf too?! And yes, you can switch back to core2 after emerge gcc-4.2.4. It's only used from emerge processes. Steffen
