I am currently moving to gcc 4.1.1-r1 using the document that I put in the URL box. After switching the gcc profile to 4.1.1-r1, quickpgking 3.4.6-r1 and removing 3.4.6-r1, a gcc --version showed 4.1.1-r1 was indeed in use. I logged out and back in, and gcc --version failed because it could find no gcc whatsoever. I had to do switch the profile again. gcc --version returned 4.1.1-r1 once again. Out of curiousity, i logged in/out and once again, it couldn't find gcc and I had to switch the profile again. The guide mentions source /etc/profile, but it seems this was not enough to make the switch stick. kojiro in #gentoo mentioned that I should do an env-update, and that indeed made it stick. What do you think of adding env-update as a step in this guide, for 3.* to 4.1.1 migration? Or, am I a lunatic?

I can reproduce this behaviour, and I agree that 'env-update' should be added to the upgrade guide.

Toolchain folks, is the behavior described in comment #0 normal?
when you upgrade to gcc-4.1 from gcc-3.4, you need to run `gcc-config` yourself to switch from 3.4 to 4.1 if you didnt do that, and then you unmerged the gcc-3.4 toolchain, you would hit the behavior described in comment #0 gcc-config runs `env-update` for you when you change profiles
Re comment #5: Yes, I had done gcc-config myself. I was following the guide, it mentions gcc-config. Perhaps something is "unusual" on my system?
i cant really diagnosis the situation if your system is working now and you cant recreate the issue ...
The profile change stuck after I did an env-update manually, which is why I requested the change, and someone else was kind enough to provide a patch for the doc, after also seeing this behavior (See comment #1). kojiro in #gentoo had suggested env-update, and as soon as I did that, the profile change stuck. Without doing it manually, every new login was reverting back to the old gcc (which i had removed as per the docs). I'm not sure what else I can say, or what else I can add, sorry. Maybe neilbags has further comment? Thank you for considering the document change :)
Okay, there were enough confirmations to warrant the change. Added env-update to the source /etc/profile instruction. Fixed in CVS, thanks for reporting.
