Hello! This is a really short, basic tutorial on switching to a multilib profile with ease. This requires no use of chroot, binpkg, and is most likely the easiest and fastest way to switch over compared to any other documentation. No chroot, no installing gentoolkit, or other utilities, just dry and simple.

1.) Switch to multilib profile

Code:

eselect profile list


Select the one that says: default/linux/amd64/13.0

In this case, it is 1

Code:

eselect profile set 1


2.) Fetch and replace headers

Download the latest stage3 multilib tarball, decompress to a temporary directory and replace headers:

Example:
Code:

cd ~/
wget http://mirrors.rit.edu/gentoo/releases/amd64/autobuilds/current-stage3-amd64/stage3-amd64-20150813.tar.bz2
mkdir -p tmp
tar xjpf stage3-amd64-20150813.tar.bz2 -C tmp/
mv -v tmp/usr/include/gnu/* /usr/include/gnu/


3.) Emerge glibc against new profile

Code:

emerge -v glibc


4.) Emerge gcc against new profile

Code:

emerge -v gcc


5.) Emerge binutils agaisnt new profile

Code:

emerge -v binutils


6.) Update world to new profile

Code:

emerge --with-bdeps=y -uvDN @world


If this isn't straight forward enough, I don't know what is. Cheers!
