Switching GCC is not working


I am using Debian Lenny.

I have two GCC versions installed - 4.1 and 4.3:
Code:
debian:/usr/bin# ls gcc*
gcc  gcc-4.1  gcc-4.3  gccbug-4.1  gccontrol
My current GCC version is:
Code:
debian:/usr/bin# gcc -v
Using built-in specs.
Target: x86_64-linux-gnu
Configured with: ../src/configure -v --enable-languages=c,c++ --prefix=/usr --enable-shared --with-system-zlib --libexecdir=/usr/lib --without-included-gettext --enable-threads=posix --enable-nls --with-gxx-include-dir=/usr/include/c++/4.1.3 --program-suffix=-4.1 --enable-__cxa_atexit --enable-clocale=gnu --enable-libstdcxx-debug --with-tune=generic --enable-checking=release x86_64-linux-gnu
Thread model: posix
gcc version 4.1.3 20080704 (prerelease) (Debian 4.1.2-25)
debian:/usr/bin#
I would like to switch that to 4.3 permanently. How can I do that?

I tried following this link but did not work for me.

Now that's a useful link, I've always set gcc temporarily never gave much thought to doing it permanently.

then there's update-alternatives again refering to group names for the alternatives.. but where do you find a LIST of the groups that can be used with update-alternatives ?

I did a little searching and ran across galternatives, which provides a gui you can use to set these options, and since you have a gui you can see all the groups for alternatives.. finally..

aptitude installl galternatives
gksu galternatives



Does anyone know where I would be able to find just a straight list ? web page, man page, etc ?

or better yet, a way to make update-alternatives to spit out a list of all the groups ? the only option in the man page appears to be --list to view the alternatives for a group you specify by name..

Thanks.


Err didn't mean to hijack the thread.. it just got me thinking. Yeah I know dangerous


never mind, I found the list..
ls /etc/alternatives
