 |
|
I would like to know if there is a guide somewhere to update my system from 2004.1 to 2004.3.
Someone on the mailling list mantionned something about changing the portage profile but I have never done this so I kinda need a step by step guide on switching to gcc 3.4.

this is what you need to change the profile
| Code: |
rm /etc/make.profile
ln -s /usr/portage/profile/<the_new_profile> /etc/make.profile
|
if you then do a update you should get gcc-3.4
and after that you can recompile everything, or just wait until eventually everything has been updated and thus everything is recompiled with gcc-3.4
don't know for sure the later works, I recompiled everything with gcc-3.4
and everytime something fails do
| Code: |
emerge --resume --skipfirst
|
hope this helps |

Eh, that's interesting for me, too. Where do I get the new profile?

Try:
| Code: | cd /etc
ln -sf ../usr/portage/profiles/default-linux/amd64/2004.3 make.profile
|
That will switch to the new profile. You'll need the latest version of portage though.
If you want to recompile everything with gcc 3.4, why not just reinstall from scratch? |

Don't want to reinstall my whole System and make all settings again. 
But thanks for your answer, I will start recompiling now

I tried to do an emerge -u world but gcc gave but the folowing the compile error occured during gcc-3.4-r2 compilation:

If you meant to cross compile, use `--host'.
See `config.log' for more details.

I can't find this config.log file.
Anyone ran into this problem ?

| I get the same error when I have multilib in my USE-flags. If you have it enabled and don't need it, try to disable it. |

| Yeah you have to disable the sandbox if you want to compile gcc 3.4... |
