Jonathan, If you're really concerned about overwriting other files, then configure GCC using the --prefix option and tell it where to put the files. For example, you could use --prefix=/opt/gcc3. That way you can put it in a totally independent directory that won't interfere with anything else on your system. And, then in the worst case, you can "uninstall" it by simply removing that directory tree. This is my preferred way of installing separate versions of GCC. Much cleaner in my opinion that sticking everything under /usr/local, or worse, /usr... Then, use the --program-suffix option to give your GCC commands a name different than the system one. That way, you can add /opt/gcc3/bin to your PATH and people can choose which compiler they want simply by using the right command - gcc would be the system compiler, gcc3 (or whatever you want) would be the new compiler. Make sense? Lyle
