libxml2[icu] is blocking qt-webkit [SOLVED]

hunky · l33t Joined: 19 Nov 2003 Posts: 702 Location: Alaska

running unstable amd_64 and got this blocker today. I've tried adding -icu to package.use on libxml2 but didn't make any difference. Sometimes I just go ahead and uninstall a blocker and expect portage to fix things up afterward. But libxml2 is depended on by lots of stuff and don't want to get stuck if I can't reinstall it later. Anyone know the best way out of this?

I just enabled the icu flag globally and the block went away.

thanks much Jaglover,

Didn't seem to work for me though.

I removed the flag from libxml2 and added it to qt-core to solve the problem here. An alternative to removing it from libxml2 seems to be to add it to qt-webkit as well.

Hmmm. I just ran into this on my several systems, and after much struggling finally figured out the problem (qt-webkit changelog says icu is now optional), so I removed the flag icu flag from libxml2 I had entered in /etc/portage/package.use, apparently some time ago. Got through the big qt updates on one system (along with gcc-4.7.0 and 50 others), and all seemed well.

Now reading here, I'm wondering if I should now go back and add icu to make.conf globally, and do an emerge -uDN @world. I was under the impression that icu was pretty important if you use unicode, and had a bad feeling about removing it from libxml2. From the ICU home page:

I had no choice, because of other dependencies. I wouldn't worry if I was you, unless you miss some functionality.

dev-libs/libxml2[icu] ("dev-libs/libxml2[icu]" is blocking x11-libs/qt-webkit-4.8.2)

chromium requires dev-libs/libxml2[icu]

same problem here

I have never seen a mess this tangled in all my years of using Gentoo.

HELP!!!

emerge -pvuDN world ends like so:

As expected, the answer is simple and lies in the ebuild - you need icu set on qt-webkit.

There is no rule that says global use flags must be set in make.conf. package.use works fine.

At this point, I don't know if setting icu as a use flag solves it, because I went through the output of emerge -pvuDN world and did a lot of manual --nodeps updates. emerge -pvuDN world doesn't spew out a mess now.

Someone should have had whichever ebuild was relevant output the usual "you need to make the following use flag changes", which did NOT happen in this case - which caused the confusion.

Thanks guys, seems to work for me, however the idea of setting the use flag globally didn't naturally occur to me.

yes for some reason the icu flag in make.conf did help.

Got the same problems, actually managed to avoid them by:

1. emerging qtwebkit without icu flag.

2. added icu to make.conf

3. emerge chromium with all the other dependencies.

Now I can enjoy this godforsaken browser until we get a proper opera again
