Bug 375091 – sys-devel/gcc-config-1.4.1-r1 -E don't print GCC_SPECS

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Bertrand Jacquin 2011-07-13 13:26:13 UTC]

To be able to compile dietlibc on x86_64 without changing the compiler manually (emerge -e system), I need to do things like :

[ "$EBUILD_PHASE" = "compile" ] && source <( gcc-config -E $(gcc-config -c)-vanilla )

Unfortunately this doesn't work as gcc-config -E doesn't print GCC_SPECS correctly :

# gcc-config.ori -E $(gcc-config -c)-vanilla
export PATH="/usr/x86_64-pc-linux-gnu/gcc-bin/4.5.2:/lib64/rc/bin:/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/local/sbin:/opt/bin:/opt/meleeweb/sbin:/usr/x86_64-pc-linux-gnu/arm-bravo-linux-gnueabi/gcc-bin/4.5.2:/usr/x86_64-pc-linux-gnu/arm-guruplug-linux-gnueabi/gcc-bin/4.5.2:/usr/x86_64-pc-linux-gnu/i386-wince-mingw32ce/gcc-bin/4.5.2:/usr/x86_64-pc-linux-gnu/i586-alix-linux-gnu/gcc-bin/4.5.2:/usr/x86_64-pc-linux-gnu/i686-pc-linux-gnu/gcc-bin/4.5.2:/usr/x86_64-pc-linux-gnu/i686-pc-mingw32/gcc-bin/4.5.2:/usr/x86_64-pc-linux-gnu/i686-w64-mingw32/gcc-bin/4.5.2:/usr/x86_64-pc-linux-gnu/mips-fonera-linux-gnu/gcc-bin/4.5.2:/usr/x86_64-pc-linux-gnu/gcc-bin/4.5.2:/usr/x86_64-pc-linux-gnu/x86_64-w64-mingw32/gcc-bin/4.5.2:/opt/ekopath-bin-4.0.10_pre20110612/bin:/opt/meleeweb/bin:/opt/meleeweb/sbin:/opt/exosec/bin:/opt/exosec/sbin"
export GCC_SPECS=""

So, attached a fix to make it works :

# gcc-config -E $(gcc-config -c)-vanilla
export PATH="/usr/x86_64-pc-linux-gnu/gcc-bin/4.5.2:/lib64/rc/bin:/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/local/sbin:/opt/bin:/opt/meleeweb/sbin:/usr/x86_64-pc-linux-gnu/arm-bravo-linux-gnueabi/gcc-bin/4.5.2:/usr/x86_64-pc-linux-gnu/arm-guruplug-linux-gnueabi/gcc-bin/4.5.2:/usr/x86_64-pc-linux-gnu/i386-wince-mingw32ce/gcc-bin/4.5.2:/usr/x86_64-pc-linux-gnu/i586-alix-linux-gnu/gcc-bin/4.5.2:/usr/x86_64-pc-linux-gnu/i686-pc-linux-gnu/gcc-bin/4.5.2:/usr/x86_64-pc-linux-gnu/i686-pc-mingw32/gcc-bin/4.5.2:/usr/x86_64-pc-linux-gnu/i686-w64-mingw32/gcc-bin/4.5.2:/usr/x86_64-pc-linux-gnu/mips-fonera-linux-gnu/gcc-bin/4.5.2:/usr/x86_64-pc-linux-gnu/gcc-bin/4.5.2:/usr/x86_64-pc-linux-gnu/x86_64-w64-mingw32/gcc-bin/4.5.2:/opt/ekopath-bin-4.0.10_pre20110612/bin:/opt/meleeweb/bin:/opt/meleeweb/sbin:/opt/exosec/bin:/opt/exosec/sbin"
export GCC_SPECS="/usr/lib/gcc/x86_64-pc-linux-gnu/4.5.2/vanilla.specs"

Reproducible: Always

i dont think this is the route we want to go to fix this.  i'll have to poke about a bit though.

[Comment 3 SpanKY 2012-02-29 20:22:47 UTC]

should be fixed in gcc-config-1.5.1
