I'm very interested in the answerto this and whether NPTL should be
part of the mix?

Thanks,

In particular, I would like a stable combination of:

gcc
glibc
binutils
--- supporting utilities.

I already have my entire system built with NPTL and Linux 2.6.8.1. I
have been using FreeBSD and noticed a dramatic improvement with the
compiler when the move from 3.3 to 3.4 took place, so I would like to
see that on my Gentoo systems as well.

Thanks in advance,

Tom Veldhouse

Almost everything on my system is built with gcc 3.4.1 or 3.4.2. The
system seems as stable as ever.

I'm using the new profile for this:

# rm /etc/make.profile
# ln -s /usr/portage/profiles/default-linux/x86/2004.2/gcc34/2.6/
/etc/make.profile
# emerge -upv world

Now you'll notice that portage wants to install the new gcc. It will not
replace your current gcc though, so you'll still have both. You can then use
gcc-config to change between compilers.

There are few programs (like optipng) that do not build *yet* with gcc
3.4.x so keep your current gcc installed just in case.

Thanks for the help. There seems to be an issue with this though.

The new gcc seems to depend on newer software than whats in stable now.
You'll have to unmask the relevant packages (glibc at least) or run a full
~arch system, like I do.

See man portage for more information on unmasking invidual packages by
using /etc/portage/package.keywords.

Oops... if you're not going to use portage version 2.0.51 which is ~ now
you should probably use the profile in
/usr/portage/profiles/gcc34-x86-2004.2 instead because Portage v. 2.0.50
does not like so called cascading profiles...
