Bug 139644 – Some infos missing in the GCC Upgrade Guide for gcc-4.1

• Status: RESOLVED DUPLICATE of bug 64615
• Product: [OLD] Docs on www.gentoo.org

[Description Marco Wegner 2006-07-08 00:13:04 UTC]

There seem to be a few infos missing in the GCC Upgrade Guide when dealing with an upgrade to the GCC 4.1 compiler series:

* it might be necessary to remove an old compiler version *before* issuing 'emerge -eav world' (see also bug #64615), especially when C++ packages (Qt, KDE) are involved

* it might be necessary to unmask a few packages before they compile with GCC 4.1 since the gcc4 patches are incorporated only in those newer versions. Examples are boehm-gc, gimp, imagemagick

toolchain, is anything like that required?

4.1 is not in arch, unstable users should know what are they doing.

no, you dont have to remove previous toolchains ... you just need to make sure whatever version you want to compile with is selected
