Your output doesnt help me understand much.

Could you please post the file

Thanks

[Rion]

Could you please post the file

maybe tomorrow. or you can try yourself

[Hwoarang]

It works fine here and thats why I am asking

SECOND problem: why qt-creator installs with prefix=/ but not prefix=/usr/ ?

[gimpel]

Anyone tried KDE 4 (.2 or SVN) on top of qt 4.9999?
If yes, do you also get all sorts of segfaults in dmesg for all sorts of KDE 4 stuff, like:

Code: Select all

KDE4 works fine, no problem at all. It's just that those messages appear quite frequently.

I'm still using qt-4.5 snapshot ebuilds, and wonder if it's a problem with those, or a problem with KDE4 vs. qt-4.5.

SECOND problem: why qt-creator installs with prefix=/ but not prefix=/usr/ ?

1)Apparently the upstream did some changes and an make the patch invalid. I ll modify it . Thanks for mention it. As you understand its hard to support live ebuilds cause the upstream is doing changes all the time

2)qt creator doesnt install much in your system. Just 5-6 libs and a binary file .

Is there a specific issue you would like me to check?

[Rion]

http://lists.trolltech.com/pipermail/qt ... 00366.html is most annoying bug for me.
of course its not overlay related..

[Rion]

just tried to remove all qt staff from my system and install qt-4.9999
got next error while compiling qt-core

Code: Select all

/var/tmp/portage/x11-libs/qt-core-4.9999/work/qt-x11-opensource-src-4.9999/tools/qdoc3/qdoc3: error while loading shared libraries: libQtXml.so.4: cannot open shared object file: No such file or directory

USE="doc glib pch qt3support ssl -custom-cxxflags -debug"

[Hwoarang]

Seems to me that I cant reprocude it here.

As i said before, dont show us only the error. I need to see the whole build.log file to understand what is going on. But since it compiles fine here I would say to try again. Maybe upstream was messing around but now its fixed

[Rion]

Maybe upstream was messing around but now its fixed

nevermind. i've already compiled with USE="-doc"
AFAIK, libqtxml is part of qt-core. probably something wrong in their makefiles. btw, MAKEOPTS="-j2".

[Hwoarang]

Still, I cant reproduce it with doc flag enabled

[Riklaunim]

There are some qt widgets on qt-apps.org, that are very usefull (qtermwidget, pictureflow - use SVN...) so what about adding them to the overlay? Also for PyQt4 I've made bindings to qtermwidget and qf-macnavbar. Poppler PyQt4 bindings: http://svn.pardus.org.tr/uludag/trunk/pypoppler-qt4/
I have some ebuild for those packages, but they are "bad", realy bad

[Rion]

i've modified install section of qt-creator-9999

Code: Select all

src_install() {
	emake INSTALL_ROOT="${D}/usr" install || die "emake install failed"
	make_desktop_entry qtcreator QtCreator qtcreator_logo_128.png \
		'Qt;Development;IDE' || die "make_desktop_entry failed"
}

now it installs as expected on gentoo.

Sounds about right . I will take a look

@Riklaunim

Sure why not . We ll fix them if they are bad. But note that I am short on time now due to university exams. I will be able to handle them in about 3 weeks or maybe another dev can find time and do it

[Rion]

arora-9999-r2 does not even try to unpack.
I guess some eclass overrides unpack function with wrong one.

[Hwoarang]

Fixed . Seems I broke it last night

Thanks for reporting

[Riklaunim]

Ok, I'll look on those ebulds and check which do work, and which doesn't and I'll publish them

[neuron]

qt-creator-9999 needs EAPI=2 set, other than that, great work

[gaelic]

i`ve got several problems with qt 4.5 and kde 4.2:

lancelot takes up 100% cpu (no problem with qt 4.4)
fonts don`t work when switching tasks (alt-tab)
strange behaviour, difficult to describe (seems to be slower, composite errors, etc.)

back to 4.4 for now.

[neuron]

My only problem so far is that kde4.2's kio_http doesn't seem to work at all, not with webkit and not with khtml, which means anything pulling online data just dies, including akregator + konqueror.

Gonna try to rebuild all of kde and see if that solves it, but I rebuilt kdelibs and konqueror (and webkit-kpart) without success.

Unable to create io-slave: klauncher said: Error loading 'kio_http'.

[gimpel]

qt-copy in kde's svn got updated to qt-4.5.0-rc1, so at least trunk should be on par with that soon.

EDIT: 4.5.0-rc1 indeed fixes all those segfaults for me.
