A: 

Are you trying to build gcc from source ? Then you need a compiler to compile it.. (that's a Catch 22...).

Can't you install a binary package with the compiler already compiled ?

Thank you so much, Andre and sth!
If you tell use which type of Linux distribution you are using (ubuntu, CentOS etc.) people might be able to tell you the command to install a pre-compiled version of gcc.(I assume you're using Linux by looking at the output of uname -s above)
Andre Holzner
I'm using Ubuntu. That would be super helpful!
From the command line, try sudo apt-get install gcc . Although I think the directory /usr/bin/gcc/ which you seem to have made initially will be in the way, so you probably have to rename the directory before installing gcc.

Sweet, it worked! Thank you so much :D
