 |

hi there,
I wonder if it is possible to change usevariables and then rebuild everything, that would be affected.
like you forgot to put "-kde -qt" or such a thing and want to unmerge those unwanted packages and to take the support out of every other build.
regards

I think if you update your /etc/make.conf, and then do an emerge --world it might do what you want.
See man emerge (it knows more than I do!) |

well, no, it does not.
I changed my use vars and added '-gtk, -gtk2' which is installed unfortunatly.
an emerge --world did nothing (no-thing!).
any ideas left?

caefer, that usechange script by dma in the thread pointed to by Brandy rocks, and should be the last step to actually cleaning gtk off your system.
The first step you'll want to perform though, is an analysis of all the programs that depend on gtk without having USE="gtk". For example gimp. USE="-gtk" on gimp doesn't make sense because it won't run without gtk. Therefore the gimp ebuild doesn't even check that USE flag. So, what this means is you need to find the list of installed packages that depend on gtk regardless of the use flags.
There are 2 programs in the gentoolkit package you can use to do this: etcat and qpkg. You can do either: | Code: | | # etcat depends x11-libs/gtk |
or: | Code: | # qpkg -q x11-libs/gtk+-2.2.1-r1
# qpkg -q x11-libs/gtk+-1.2.10-r10 |
Now you need to look at the list and decide, do you really want to throw out gtk? Are there some apps on the list you really need?
If you don't want any of those packages, then fire away by just unmerging each one. Finish up by unmerging gtk itself: | Code: | # emerge -C =x11-libs/gtk+-1.2.10-r10
# emerge -C =x11-libs/gtk+-2.2.1-r1 |
Now, you can run that usechange script to find all the packages you built with "gtk gtk2", and re-emerge them so they won't have a dependency on the gtk. |
