[gentoo-user] who wants to downgrade my gcc ?

[Helmut Jarausch]

Hi,

this one is puzzling me.
I have gcc-4.4.4-r1 installed here.
emerge -vp sys-devel/gcc:4.4 would re-install this.
But,
an emerge --update --newuse --deep --tree  --with-bdeps y @system @world
wants to downgrade it to gcc-4.4.3-r3

How can I find out, why?

Many thanks for a hint,
Helmut.

Adding the -t option may help.

Never mind.  I saw it in there right after I hit send.  No clue why or how.

What does emerge --update --newuse --deep --tree  --with-bdeps y @world

actually say?

I'm not sure this is correct but I have to ask this.  Since gcc is a 
system package, it wouldn't try to upgrade gcc even if one was available 
would it?  I guess if something in world just had to have that or a 
newer version then it would pull the newer gcc in but otherwise it would 
skip it right?

@world includes @system. But the problem is not that emerge world is
skipping it but that it wants to downgrade gcc:4.4.

So obviously he has 

<sys-devel-gcc-4.4.4

or similar in a BDEPEND somewhere

Which is why the actual output fro emerge --tree is important.

 From my understanding, world includes @system but @world does not.  I 
know here on my rig, I run emerge -uvDNa world and it updates everything 
installed including deps and the system packages.  If I run @world, it 
skips the system packages.  At least that is the last time I tried it 
which was not to long ago.

One reason I remember this is because of the discussion I had with the 
devs on -dev.  That is why @system is in /var/lib/portage/world_sets.  I 
noticed a few weeks ago that there are a couple others added to it as 
well.  The devs did it that way so that when folks like me upgrade the 
old fashioned way and just use world instead of @system and @world.

Has this changed?

No, the world_sets file still includes @system by default, which is why
@world includes @system.

The additions are from when you emerged sets, which adds then to
world_sets.

But if you removed, temporarily, the @system from the world sets, then 
you get just one.  Did this a while back and it worked at the time.  Not 
going to say it would work today tho.  We all know how portage is.  It 
is like shooting a bullet with another bullet.  ;-)

As was pointed out to me many times, @system is not the same as system.  
Same can be said for world and @world.

Sorry so long to reply.

Among many other things
[ebuild     UD]    sys-devel/gcc-4.4.3-r3 [4.4.4-r1]

I think Thomas' hint helped a bit
equery d gcc shows one suspicious line
dev-java/gcj-jdk-4.4.3-r1 (~sys-devel/gcc-4.4.3[gcj])

where dev-java/gcj-jdk-4.4.3-r1 comes from the java-overlay.
This, in turn, has been pulled in by dev-java/icedtea-6.1.8.0

This dev-java/icedtea-6.1.8.0 from the java-overlay.
There seems to be no dev-java/gcj-jdk for gcc(gcj) 4.4.4

I have removed java-overlay from /etc/make.conf and rebuilt icedtea.
It's still compiling but I think this solves it.

Many thanks for all who helped me,
Helmut.


Thanks for solving that mystery,
Helmut.
