Just thought I'd let you all know. It isnt OFFICIALLY released yet, but it's on the gcc FTP and it's the completely frozen RTM version :)

ftp://ftp.gnu.org/gnu/gcc/gcc-3.4.3/

Mainly, this is a bugfix release. GCC 3.4 is becoming very stable as of late :D here is the (incomplete) changelog:

3.4.3 is in the portage tree for ~arch and it looks like the "f77" use flag has changed to "fortran".(?)

I had a little trouble after a reboot but got KDE started again after I did a "gcc-config i686-pc-linux-gnu-3.4.3" and "fix_libtool_files.sh 3.4.2". I don't know that the fix_libtool part is needed though but I did it anyway.

i just emerged 3.4.3, and now i can't emerge anything.
emerge even die with all sort of errors related to gcc.
next time i've got gcc working i will build a precompiled gcc package just in case i need to downgrade but can't compile an older version.

thanks for the tip Oktane, i already found a solution in bugzilla.
live-cd is my last resource, it's too easy to fix things this way, there is no fun!

running "gcc-config i686-pc-linux-gnu-3.4.3" fixed the problem for me.

Yeah, it doesn't switch automatically to 3.4.3, and because there's no 3.4.2 (or whatever you had before emerging 3.4.3), it doesn't work.

For me too.

Before doing it and after having updated GCC, I had this frightening error nearly everytime I wanted to start a program (it didn't for pySoulSeek) :

Code:
error while loading shared libraries: libstdc++.so.6: cannot open shared object file: No such file or directory


EDIT :
Seems like the number for this bug is 70436.

Worked fine with me, after doing a "gcc-config 3" and a "fix_libtool_files.sh 3.4.2" and finally adding GCC_SPECS="/usr/lib/gcc/i686-pc-linux-gnu/3.4.3/specs" at the end of /etc/env.d/gcc/i686-pc-linux-gnu-3.4.3 (this last one is a bug, already reported on bugzilla). Pretty smooth, all in all, other than the bug part...

Does anyone know if they fixed the sse2 bug for P4's in this release. I hope they do sometime, so I can use gcc 3.4.x and have sse2 optimizations.

Done the business for me. Don't you just love the forums, just when you start to panic in with the knoppix cd - www.forums.gentoo.org - find solution - print - fix - reboot -JOB DONE.

IMHO these forums are without doubt the biggest selling point (giving away point :lol: ) of Gentoo. Hopefully M$ will not catch on

I just upgraded the slower box and I had time to notice that it has a little message that says you have an existing gcc profile that is valid so it is leaving it be, but if you want to change it you can and it tells you how, then it does a fix_libtools*, then it finishes the emerge and unmerges your 3.4.2 which makes the first part invalid because it just took away your "existing gcc". This flies by so fast on the athlon64 I usually don't have a chance to even notice it or read any info notices before it removes the old version of a package.

I still have 3.3.4-r1 installed so this could be the reason it thinks I'm ok and doesn't switch to the new gcc.

here's what I posted in another thread about it:

The gcc-config fix, listed above, fixed it for me also. But, I came very close to totally dumping Gentoo because of the way portage handled this upgrade.

This is why I make this complaint:
If there is a new version of portage available to be emerged, portage itself will say that it will stop and reload itself before continuing with any other emerge requests in the current list (like if you do an emerge -Dvu world).

Why in the world (no pun intended) wouldn't the Gentoo developers make provision for the same kind of "reloading", as it were, for such major changes as gcc 3.4? It makes not sense whatsover. In fact, I couldn't even finish the emerge request that I was doing today because of this lack of forsight. (This type of change could also require user interaction before continuing with that or any other emerge slated to be completed.)

It also caused me to lose critical time today when kde wouldn't come up because of this oversight.

Really? How hard could it be to integrate that kind of stopage and warning into portage when there are such critical changes that WILL affect your system in such a dramatic way?

I nearly stabbed myself in the face when I upgraded portage and could get nothing working.

I ran gcc-config, I manually updated some configs in /etc/env.d, and ran ldconfig && env-update && source /etc/profile as many times as possible.

I downgraded GCC and plan not to upgrade until an -r1 is released to fix this.

It's badly broken for me too.

I've run gcc-config and my ld.so.conf has the right directories in it, but the file just isn't anywhere to be found:



Code:

# ls /usr/lib/gcc/i686-pc-linux-gnu/3.4.3/libstdc++.*
/usr/lib/gcc/i686-pc-linux-gnu/3.4.3/libstdc++.a   /usr/lib/gcc/i686-pc-linux-gnu/3.4.3/libstdc++.so
/usr/lib/gcc/i686-pc-linux-gnu/3.4.3/libstdc++.la
# ls /usr/lib/gcc-lib/i686-pc-linux-gnu/3.4.3/libstdc++.*
/usr/lib/gcc-lib/i686-pc-linux-gnu/3.4.3/libstdc++.a   /usr/lib/gcc-lib/i686-pc-linux-gnu/3.4.3/libstdc++.so
/usr/lib/gcc-lib/i686-pc-linux-gnu/3.4.3/libstdc++.la


I tried the fixtools script and re-emerging gcc 3.4.3. Is there some tool that erases/generates this library?

It isn't released yet (still ~x86), so you still have time to go file a bug report and ask for appropriate handling from within the ebuild, or wherever handling would be appropriate.

The 3.4.3 ebuild seems to be slotted, so it should leave 3.3.x (or whatever) on your machine, which should leave you with a working compiler in most cases. If one has already been playing around with the 3.4 series, though, I guess it would remove that package and leave you without a compiler. However, it should be noted that you would have to be playing with experimental packages, and shouldn't really expect hand holding.

If it does, in fact, remove 3.3.x even though it's slotted, and could leave even people how aren't experimenting without a default compiler, then that is most likely a bug, and should be reported.

Hmm, I just emerged GCC 3.4.3 and ran gcc-config, everything works very well. What kind of problems do you guys have?

They already have, but abandoned the idea many many moons ago. The Microsoft forums on CompuServe used to be very good, but that was about 10 years ago.

I agree that this would be a valuable "feature," but it would be quite lame to quit using Gentoo over something as trivial as that... if you're tired of fixing stuff that breaks once in awhile, then switch to arch from ~arch and most of these bugs will be fixed by the time the packages are unmasked for you.

Its because of the comming GCC 4.0 migration to F95. Read the " f77 is now just plain old fortran in preparation for gcc4" thread on gentoo-dev@gentoo.org after further information

I don't know if this has been posted yet, but this is what worked for me.

I emergeed gcc 3.4.3, but it was still lookin for the 3.4.2 directory. I just added a symlink.

Code:

cd /usr/lib/gcc/x86_64-pc-linux-gnu
ln -s 3.4.3 3.4.2


of course change x86_64-pc-linux-gnu to whatever system your running. Worked like a charm for me.

correct way it works =)

1. emerge gcc
2. run
Code:
gcc-config -l

The "-l" is a "L".

select the profile you want to use

3. run
Code:
gcc-config NUMBER_OF_THE_PROFILE_YOU_WANT
