From the Zug How-to's
Note that many of the newer distributions now use GCC3.2 or later as their default compiler. This means that when compiling for the desktop it will not be able to link to the sdk files as they were created using GCC 2.95. To fix this problem you need to install 2.95 for your distribution.

Does anyone have, or know of a simple how-to for installing and using multiple versions of gcc on a linux box? I was looking at graft... but there must be an easier way?

I have a little extra time during the Holidays and would like to try some things without damaging my current setup.

The listed below are the basic steps and you would be done.. to read the complete article you can visit http://www.tarunworld.com/index.php?option...id=26&Itemid=36

1. Copy the bz2 file to a director say /usr/src.
2. Make a dir say named gcc 3.5 in /usr/src.
3. Untar the contents of the zip file in this directory.
4. go to the directory gcc 3.5 as cd gcc3.5
5. on shell give the command as /usr/src/gcc3.5/configure --prefix=/opt/gcc
6. on shell run make bootstrap.
7. on shell run make install(do it as root).
8. The gcc would be compiled 3 times and you might have to wait a while.
9. After the process is completed on shell run export PATH=/opt/gcc/bin:$PATH.
10. This command appends the gcc path to the environment path variable.
11. Now check gcc --v and you would get version as 3.5.
