[gentoo-dev] About gcc3.1.1

[RYMNAT_ADSL]

Dear people at Gentoo,

  Yesterday I installed gcc3.1.1 in my Gentoo sytem. The problem is 
that, as it needs gcc (2.95.3) to be compiled, after the installation I 
have 2 gccs. One, the 2.95.3, is gcc and the other one, 3.1.1, is gcc3-
1. I want to make 3.1 my default compiler for C, C++, etc. How do I do 
it?. By now, I have moved gcc and cc to gcc-old and cc-old and made 
symbolic links to gcc-3.1, but it seems not to be an elegant way.


Thanx.
Igor Modino

You don't need to do anything unless the ebuild screws with the install
process.  The gcc install process makes the last version installed the
default version.  Other versions can be invoked with the version flag.

Caveat:  The frontend installed with gcc3.x is incompatible with gcc2.x
according to the web site so it will not be able to invoke your 2.95.3
compiler.  Of course it's possible that the ebuild does something to
the install to get around this problem.  I have no idea as I only use
the latest compiler.

Not in Gentoo land.  The ebuild have a function that tries to "detect"
if it should be installed as the default, or alongside 2.95.3.  If
you are for instance not in the gcc3 profile, then it wont install
as default, because the "default-1.0" profile will break with only
gcc3 installed.
