upgrading gcc

Message

I tried to upgrade to gcc 4.3.3. So I unmasked it, and also glibc. Everything emerged successfully. However, when I go "gcc --version" it still shows me as gcc 4.1.2

is there something else I need to rebuild?

thanks

You need to use gcc-config to set the current system compiler to the new gcc.

What is the output of gcc-config -l ; which -a gcc ; gcc --version? Have you sourced /etc/profile after running gcc-config?

I am running it in a terminal so i dont know ho to copy the output.. i will explain the output
gcc-config: show both 4.1.2 and 4.3.3. Next 4.3.3 there is a green *
which -a gcc: only talks about 4.1.2
gcc -v: only talks about 4.1.2

yes i have sourced

Where can i find a guide for upgrading from 4.1.2 to 4.3.3??? following the howto from 3.3 to 3.4 i hit so many issues that i lost a night of sleep!! and still im runnin rev hoping thet i will not hit packages who are not unable to find libgxx 3.4.9 or something like that...
I'm upgrading after stage install..

The green asterisk from gcc-config -l means that is the compiler the system is currently set to use. With it being next to 4.3.3, it *should* mean 4.3.3 is what it is set to use.

env-update && source /etc/profile didn't help? You can try doing a gcc-config # (where the # equals the number next to the version you wish to use). Even though it is set to 4.3.3, you can reselect that. Once it's set to 4.3.3, you go ahead and do a emerge -P gcc which will prune the old versions so you will only have the new one on your system.

PS. Describe running in a terminal issue? If its within an X session, you can usually just select the text, right-click copy. Or you can use Ctrl + Shift + C to copy with the xterm (or w/e you are using). If its with PuTTY (like from a Windows box), just highlight the text and PuTTY auto-copies w/e you highlight when you highlight.
