Few months ago I was using gcc 4.6. In order to get C++11 functionality I upgraded to gcc 4.7 using a PPA. Today gcc 4.7 was recommended to me through the update manager. I just mindlessly clicked "Install all available updates".
Now when I try to build my project in C++, I get the following error:
The first thing that came to my mind was to uninstall gcc and install it again through the Synaptic Package Manager.
But something tells me that things may not be as straightforward as it seems. Compiler is an essential part of the OS and I am afraid I can lose the capacity to install anything. I remember that when I was upgrading to gcc 4.7 from gcc 4.6 things were also not so trivial.
Please, where can I find more information on the subject? Is it ok to just reinstall the gcc using Synaptic?
