Activate GCC4.7

[mohmsslk]

Hello,

I have installed GCC 4.7 but when I run gcc --version I get gcc 4.4, how activate 4.7 to use it?
I have CentOS 6.8.

Thank you

If that was from an SCL like devtools then you need to use the scl enable ... command

hello,

I have installed new gcc by compiling on my own, the new gcc make problem and I cant access to my PC.
the source http://jotmynotes.blogspot.com.es/2016/ ... os-67.html and see the last part(Check rpm installed) to understand.
Any idea to solve that?

Thank you

Thank you very much it works well, but now I need version 4.8.5.

Base system : gcc 4.4.7
devtoolset-3: gcc 4.9.2 (EOL since Oct 2016)
devtoolset-4: gcc 5.2.1
devtoolset-6: gcc 6.2.1

Devtoolset-2 includes gcc 4.8.2 and is still available. It was good enough to build RHEL 7.0, so it should be good enough for you, too. Gcc 4.8.5 isn't available for CentOS 6. But it's available as the system compiler in CentOS 7.3.

Don't install from source. Use one of the devtoolset versions.

That separate thread is now merged into this one since it's a continuation of the same thing. And, no, we don't support installing anything from source, let alone something like gcc. If it's broken your system either undo what you did or reinstall.
