[gentoo-user] GCC 6.2.0

[gentoo-user] GCC 6.2.0

[Maxim Reshetnyak]

Hello!

1) Can you help me with installation of gcc 6.2.0 at Gentoo for amd64?  
I need it for the parallel computing. I tried to use ~amd64, but it is 
only gcc 5.4 there. And I did not find higher version in the layman's 
list (layman -L ).

2) Has it sense to update the kernel to the higher versions for gcc 
6.2.0? If yes, what should be done firstly: gcc or kernel?

The computer will be used just for the openmp, mpi and gpu parallel 
computing experiments (before start the code at the clusters).

Maxim.

6.2.0 is in the portage tree but keyword masked. To install it, add 
"~sys-devel/gcc-6.2.0 **" to /etc/portage/package.accept_keywords. Then
use gcc-config to enable it globally or call the 6.2.0 executable
directly when needed if you don't want to risk using it for system
compiles.
