［请教］麻烦大了，必须强制从KDE4.2.4升级到KDE4.3吗？

以前升级都正常，今天准备升级
输入emerge -avuDN world提示要“qt3support”这个USE。也就在make.conf中加入了qt3support这个标志。

再次运行emerge -avuDN world 不得了，出现下面的提示：

请问：这种情况如何办？ 是否要我全部升级到KDE4.3呀？

恩，你先把4.2的版本卸载掉，然后再装新的。

看看哪个软件需要qt3support这个USE，把它emerge -C ！

http://www.gentoo.org/proj/en/deskto...ml#kde_portage

多關注文檔有益身體健康。看後面的 Upgrade Troubleshooting。可能強行emerge -1 --force kdelibs:4.3會可行

4.3.2好像出了，升吧升吧。

谢谢上面各位的解答，如果要升级到4.3，好麻烦呀。有其他的好办法吗？

最近在干活中，怕把系统弄坏了，影响工作进度。

实在不行，就不先升级了

不升级又不影响使用，话说我现在办公还是觉得用kde3.5顺手点，自己本本上kde4.3.2是装酷用的。

升级kde这种动作一般都是放到晚上睡觉时才做。机是为人服务的，不是用来折腾的。

哈哈，说句实在话。我现在用KDE3.5觉得非常别扭，所以1月前，考虑半天还是用了KDE4.2.

不升不就行了,,没问题就不要升级了,升级一次麻烦死了~直接mask掉把

就怕楼主 会一边纠结要不要升级，一边看着emerge的block提示郁闷

呵呵，现在就是这样的心态，哈哈

那就升，我覺得沒有什麽的。KDE升級很好。

還有，根據 KDE 組的意思 Portage 2.2 很不錯。

哈哈，刚升级了内核到2.6.30-r5。最近的急活也完成了。看看吧，哈哈，晚上升吧

想了想，还是先不升级了。去掉qt3support后运行emerge -avuDN world后显示：

It may be possible to solve this problem by using package.mask to
prevent one of those packages from being selected. However, it is also
possible that conflicting dependencies exist such that they are
impossible to satisfy simultaneously. If such a conflict exists in the
dependencies of two different packages, then those packages can not be
installed simultaneously.

For more information, see MASKED PACKAGES section in the emerge man page
or refer to the Gentoo Handbook.


emerge: there are no ebuilds built with USE flags to satisfy "~x11-libs/qt-core-4.5.2[qt3support,-debug]".
!!! One of the following packages is required to complete your request:
- x11-libs/qt-core-4.5.2 (Change USE: +qt3support)
(dependency required by "x11-libs/qt-qt3support-4.5.2" [ebuild])
(dependency required by "kde-base/okular-4.3.1" [ebuild])
(dependency required by "world" [argument])


请问：是否屏蔽掉 okular 就可以了？x11-libs的不能屏蔽吧。如果需要屏蔽，那么应该如何屏蔽？

谢谢

kde4本身就依赖qt3support
