[gentoo-user] emerge update gcc downgrade

[Kraus Philipp]

Hi,

I run in a virtual machine a gentoo (~x86) system. I synced the portage
tree at the weekend an run emerge --update

The update runs without errors, but emerge installed the gcc 4.3.4,
but on the system is the 4.4.3 installed

[ebuild  NS   ] sys-devel/gcc-4.3.4 [4.4.3] USE="hardened mudflap nls  
nptl openmp (-altivec) -bootstrap -build -doc (-fixed-point) -fortran - 
gcj -gtk (-libffi) (-multilib) -multislot (-n32) (-n64) -nocxx -nopie - 
objc -objc++ -objc-gc -test -vanilla"

After the update I run "emerge --depclean" and the 4.3.4 is unmerged  
and now
I run emerge --update the gcc should installed again

gcc-config -l shows only i686-pc-linux-gnu-4.4.3 whitch is set
gcc-version: gcc (Gentoo 4.4.3 p1.0) 4.4.3

and I mask only 2 packages
 >=net-fs/netatalk-2.0.3
 >app-emulation/open-vm-tools-0.0.20090824.187411

I run the kernel (kernel.org) 2.6.33.2 and I don't use distcc at the  
machine

Can anybody help me to fix the gcc problem? I only need the 4.4.3 gcc

Thanks

Phil

Check your /var/lib/portage/world file. You'll probably find that SLOT 
"4.3" is pinned:

   sys-devel/gcc:4.3

If so, remove this line.

I do not understand this, but anyway: Add the -t / --tree option you your 
emerge command, I guess then you can see which package pulls in the old 
gcc. I assume that something needs the old gcc for building, but when it 
is built, the old gcc is no longer needed, so emerge --depclean will 
remove it.
Do you have "--with-bdeps y" in your EMERGE_DEFAULT_OPTS in make.conf? 
Otherwise this should not happen. And if it is set like this, depclean 
should not remove it. Hmmmmmm.

You could also emerge -n sys-devel/gcc:4.3 in order to add it to your 
world file. Depclean would not remove it then. No real solution, but it 
would spare you the emerges. Or you build a binary package with quickpkg, 
and use the -k option to emerge, so it will emerge the binary instead of 
building from scratch every time.

What's the output of 'emerge -pt world'?
That should show you what package is pulling gcc-4.3.4 :-)

You have the +hardened USE flag set.  Did you just recently switch to
the hardened profile?  If so, make sure you followed the upgrade guide
for hardened profiles, which should have warned you what was going to
happen here.

In the base system, gcc-4.4 is still masked off for hardened users
because it's not quite ready for production use.  If you want to use gcc
4.4 and all it's hardened features, you need to do two things:

1. Add the hardened-development overlay, for example using layman:

basement ~ # layman -a hardened-development

2. Unmask gcc-4.4:

basement ~ # mkdir /etc/portage/package.unmask
basement ~ # echo '=sys-devel/gcc-4.4*' >>
/etc/portage/package.unmask/hardened

After that, you should get gcc 4.4.3 back.

Good catch, Mike! In my haste, I overlooked that detail entirely.
