So I'm working on a project and I wanted to use some C11 features for C. To use those features GCC 4.7 is required, so I went to synaptic and looked up 4.7, and I found the packages gcc-4.7-base so I installed it[1].
So now that gcc-4.7-base is installed I expected to be able to use 4.7, but no, when I do gcc --version
it still shows 4.6.3 even more, when I try to directly call 4.7(via /usr/bin/gcc-4.7
) it doesn't exist, though a gcc-4.6
executable does exist.
How do I "activate" GCC 4.7? I read here, you do some crazy stuff with update-alternatives
, but it doesn't work for me as the gcc-4.7
executable doesn't actually exist on my machine.
Notes: 1. I also saw gcc-4.6-base, so I figured I'd uninstall it, but synaptic attempted to remove every package I had installed and install a Java runtime, so for obvious reason I decided not to remove it.
