 Posted: Wed May 09, 2012 3:55 pm Post subject: Which gcc version am I running? [SOLVED] |
 |
|
When doing "gcc-config -l" I get following:
gcc-config -l
[1] x86_64-pc-linux-gnu-4.3.6
[2] x86_64-pc-linux-gnu-4.4.5
[3] x86_64-pc-linux-gnu-4.5.3 *
[4] x86_64-pc-linux-gnu-4.6.3
from which I assume I'm using 4.5.3. "emerge --info" also gives me:
emerge --info
Portage 2.1.10.49 (default/linux/amd64/10.0/desktop, gcc-4.5.3, glibc-2.14.1-r3, 3.2.6-ck x86_64)
However, when I run "echo; gcc --version; echo; g++ --version; " I get following:
gcc (Gentoo 4.4.5 p1.2, pie-0.4.5) 4.4.5

Why the differences, and which version am I actually using. I would like to use 4.5.3 and go through the "env-update && source /etc/profile" routine when changing compilers. I also re-emerged libtool.
Thanks.

gcc and g++ are symlinks. What does | Code: | | #ls -ails /usr/bin | grep gcc |
output ?

You can also try a gcc-config --force

gcc-config -B
/usr/x86_64-pc-linux-gnu/gcc-bin/4.6.3
gcc-config -L
/usr/lib/gcc/x86_64-pc-linux-gnu/4.6.3:/usr/lib/gcc/x86_64-pc-linux-gnu/4.6.3/32
gcc-config --force 4
* Switching native-compiler to x86_64-pc-linux-gnu-4.6.3 ...
But, still,
echo; gcc --version; echo; g++ --version;
gcc (Gentoo 4.4.5 p1.2, pie-0.4.5) 4.4.5.....
g++ (Gentoo 4.4.5 p1.2, pie-0.4.5) 4.4.5....
I guess the consensus is that I'm running what gcc-config -l returns (in this case, 4.6.3), and I'll leave it at that.
(I got into this because my efforts to compile Firefox 12/Thunderbird 12 fail with an error message that suggests it's a compiler problem, which I've never had before with FF/TB ebuilds.)
Thanks for prompt feedback. |

Removing 4.4.5 did the trick. Without doing anything else,
echo; gcc --version; echo; g++ --version;
gcc (Gentoo 4.6.3 p1.0, pie-0.5.1) 4.6.3....
g++ (Gentoo 4.6.3 p1.0, pie-0.5.1) 4.6.3....
And, I was able to emerge Firefox 12/Thunderbird 12 with newer compilers. Not clear to me why I remained stuck in 4.4.5 despite what gcc-config was reporting.
Thanks again for the help. |
