Hi, Which part of the instructions didn't you understand? Basically, you shouldn't need to specify many configuration options other than --prefix so that you install it into a non-standard directory, so that it doesn't conflict with your default compiler installation. For example, you could install it in /opt/gcc331 or something like this. To do that, follow the directions for untarring the source, create your build directory according to the instructions, and then run your configure command similar to this: ../gcc-3.3.1/configure --prefix=/opt/gcc331 Unless you have special needs, you probably don't need to specify any more options. Once the configure is complete, run "make bootstrap" to build the compiler (this will take a while unless you're on a very fast box), and then "make install" in install it. To use the new compiler, you'll need to add /opt/gcc331/bin (or whichever directory you decided to use) to the _beginning_ of your path: export PATH=/opt/gcc331/bin:$PATH You should then be able to use your new gcc. When you're ready to rebuild and start everything over again, you can simply remove the /opt/gcc331 directory and install your new build into it again. Does that help?

I need to modify (several times) gcc for my thesis, where can I find some "Steps to install gcc for dummies" in order to do this many times? thanks Atte. Manuel Baez L.
