Question about GCC.

[donatello]

Can I install another version of GCC (I want to use the judge's version 2.95) but I want to keep the newer version as well for other contests) in parallel and use both together (with say different commands)?

Yes. In fact, under most linux distributions this is a common thing, and it is directly supported by the packaging system. You will have several binaries called gcc-version, and a symbolic link gcc pointing to one of them, the default one.

Code: Select all
