 Posted: Wed Jan 09, 2013 9:26 am Post subject: [solved]emerge --depclean deleted gcc-4.6.3 |
 |
|
hi,
in the morning i ran: | Code: | emerge --update --deep --with-bdeps=y world
emerge --depclean
revdep-rebuild |
and updated gcc. But depclean removed the older version 4.6.3 (I read that one has to be cautious with emerge --depclean and I guess it was rather stupid to let depclean remove gcc  but I don't understand why, because emerge --update --deep world installed the new version..!?)
Now I can't compile packages and at the moment even worse I can't compile my C-programs, I've tried to reinstall gcc-4.6.3 but it doesn't compile, what can I do now?
output of gcc-config -l: | Code: | * gcc-config: Active gcc profile is invalid!
[1] x86_64-pc-linux-gnu-4.6.3
[2] x86_64-pc-linux-gnu-4.6.3-hardenednopie
[3] x86_64-pc-linux-gnu-4.6.3-hardenednopiessp
[4] x86_64-pc-linux-gnu-4.6.3-hardenednossp
[5] x86_64-pc-linux-gnu-4.6.3-vanilla

gcc-config will show a * next to the active profile. You have to manually select a profile using gcc-config. So if you upgraded gcc and removed the old version and did not select a new profile in between, you'll get the error that you did.

Awesome, this solution worked for me too. Minor note: there is a space between gcc and -config that shouldn't be there.  |

"gcc-config 1" worked for me (did not had to force it *g*).
But surely, that could have been handled better from a usability-point-of-view. Its not that i had expected the regular update procedure (and "emerge --depclean" is recommended by emerge after @world updates) to break the following revdep-rebuild...
Maybe, unmerging software currently "selected" to be used (especially by portage itself!) should not be that easy (it's almost automatic now). There should be a hint, that the package is in use and how to change that. In the case of gcc it should mention use of gcc-config to select another version and refuse to unmerge the currently selected one.
And of course, "emerge --depclean" should know about packages currently in use and not suggest their removal (at least for the packages needed by portage itself). |

when in doubt, run emerge and depclean with the -p flag
BEFORE actually emerging or deleting. Yes it takes a little more time
but saves much aggravation.

I did use emerge -vatDuN and therefore saw, that gcc was about to be updated along with 30+ other packages. I even added the new and default-deselected cups use flag, introduced in some packages, to my make.conf avoiding breaking the printing functionality. I also researched udev and decided to just disable that use flag where it got newly introduced - do not know, if that will break something or not as i just did not find enough information about it (but had a bad feeling about udev trying to sneak into the GPU driver. Looks like udev is building up dependencies to make itself indispensable before becomming unseparateable from systemd)...
I saw the old gcc in the depclean list afterwards and thought "well, i just upgraded -> the old one is no longer needed".
I use Gentoo for only two years now and never used gcc-config before. The encountered behaviour was surprising and showed just once again that updating Gentoo is a lot more risky than updating other Distributions.
I really like Gentoo and will stay with it. Only wished updates would be less surprising. |
