Gentoo switches to gcc 3.4.4 on x86

I am glad to see (most) everyone is making out well with the upgrade. I on the other hand am going to hold off for a bit. I know something will break for me :roll:

Wouldn't it be still better to bootstrap in addition of the instructions given in the upgrading guide ?

How important is it to upgrade to GCC 3.4? What are the benefits? I heard that GCC 3.3.x produces more RAM friendly code - is that true and should I not upgrade on a system with little RAM (256MB)? Hope these are not too many questions :-)

Hello Guys.

I've tried to emerge to gcc-3.4, following the upgrade guide..
in the guide i decided to go by the safe way

(just in case) but the things dindn't went well...
during the merge (emerge -e system) i get a following error:

File "/usr/bin/emerge", line 3112, in ?
if not mydepgraph.xcreate(myaction):
File "/usr/bin/emerge", line 1424, in xcreate
if not self.select_dep(myk,myuse=binpkguseflags):

and so on...

and it finish with
OSError: [Errno 30] Read-only file system: ' /var/cache/edb/dep/aux_db_key_temp.portage_lockfile'

and i cant do anything more...
what went wrong ???
do i need to install again my whole system???

cheers,

My main gentoo box is a 966 pIII with 384megs of RAM. I also have an AMD 2400+ with 512megs RAM that still only has windows (I use it for audio recording with windows only apps). I want to harness the more powerful computer to do all the compiling for the gcc update, and I was wondering if this idea would work.

1) export my / on my gentoo box as an NFS share (need to learn how to do that too, but i'll search around)
2) boot a liveCD on my more powerful computer and mount the NFS share.
3) chroot to the NFS share
4) do all the compiling/etc using the more powerful processor, but chrooted into the other box, so the correct compilers will be used.

Will compiling on the wrong CPU but for the correct CPU work?

EDIT: found https://forums.gentoo.org/viewtopic-t-407866.html , looks like i'm off to look at how to do nfs.

I'm very happy to use both the stable branch and gcc-3.4.4!!! I've been waiting for this so long...

Thanks to Gentoo developers!!!

I got the new gcc in yesterday's upgrade, then I glanced at the website, and saw the news about it, including the migration guide. The funny thing is this:

I just noticed that gcc changed when suddenly the OpenGL programs I am working on stopped compiling. Thank you Devs! ;-)

Guess maybe I should be more careful with updating packages.
Followed the guide and got them working, but didnt feal like this.
I wonder why a major upgrade like this isn't incorporated into a version change, like putting it in 2005.2 or something like that.

There are no new releases

All the so-called releases are just updates to the LiveCD and new stage tarballs.

Stop whining or stop upgrading, or both.

Yay... Just finished a two day compile of emerge -e world and everything is just peaches. The only gripe I have is that the compile stopped three times and I had to emerge --resume to get the show on the road again. Which is a damn waste of processor cycles if it happens when you've JUST gone to bed.

Packages it failed on: nget, php5 (recode and mysql use flag conflict) and another one which I can't remember. :oops:

Thanks devs! Great job.

gtkhtml and vlc were the only packages that I had to use emerge --resume --skipfirst with (one other died but when I did emerge --resume it went on just fine). It ran from 2 PM on Saturday to 4:30 AM this morning. The two stopped compilations other than vlc happened while I was asleep so it set me back about 8 hours.

Everything is running great now though.

Just adding another success story. Upgrade came off on my HP zt1000-ic P4-M lappy, using the "safe method," with no troubles. Thanks, devs!
