Split Qt 4.4.0_rc1 has just been added to the tree under package.mask. x11-libs/qt-4.4.x is only a meta package which nothing should depend upon directly. Before we unleash it on ~arch we would prefer for all packages that depend on things like e.g. =x11-libs/qt-4* or $(qt4_min_version 4.2) to have their dependencies updated. Typically the updated dependencies would look like e.g.: DEPEND="|| ( ( x11-libs/qt-fooA:4 x11-libs/qt-fooB:4 ) >=x11-libs/qt-4.2:4 )" Where fooA and fooB are the split qt packages it requires. To use the SLOT dependencies EAPI="1" is required before inheriting any eclasses. We plan to get rid of the atrocity that qt4_min_version is, so starting from the Qt 4.4.0 release, we won't be updating the list of versions is spews out, anymore. Please stop using it.
Hello, I don't understand why you intend in making qt release candidate at ~arch, why not wait for release? It would be difficult for people to update into none stable core package.
Hi folks, Here's my question: you advised not to directly depend on x11-libs/qt-4.4.x However, this causes my system to not have it installed at all (only the individual x11-libs/qt-fooA:4 packages). This, in turn causes the qt4.ebuild to fail in line 89, i.e. QT4_BEST_VERSION="$(best_version =x11-libs/qt-4*) causing QT4_BUILT_WITH_USE_CHECK to fail as well. Is there something I am missing? Thanks, Markus

Thanks much, I appreciate it! Best, Markus

That's the plan actually, we do have to get dependencies fixed before we can unmask it. While the _rc1 seems rather solid, we'll wait for the release to unmask anything, there're still a few FIXMEs left in the ebuilds..
(In reply to comment #0) > DEPEND="|| ( ( x11-libs/qt-fooA:4 x11-libs/qt-fooB:4 ) > >=x11-libs/qt-4.2:4 )" Please everybody be aware that the above example is subtly misleading. It might lead your package manager into believing that you'd really be okay with having x11-libs/qt-4.4:4 installed, but that's just a meta package, which would satisfy the dependencies, but at considerable cost in compilation time. In most (all?) cases the syntax should go like this: DEPEND="|| ( ( x11-libs/qt-fooA:4 x11-libs/qt-fooB:4 ) =x11-libs/qt-4.3*:4 )"

This should be fixed by this commit: "zlin * gentoo-x86/eclass/qt4.eclass: Try to handle all flags in QT4{,_OPTIONAL}_BUILT_WITH_USE properly for split qt to avoid duplicating the same code in pkg_setup in lots of ebuilds. See bugs #217161 and #229193." http://sources.gentoo.org/viewcvs.py/gentoo-x86/eclass/qt4.eclass?r1=1.43&r2=1.44

It becomes completely unmaintainable when a package needs >= -4.2.3-r7:4. When this bug has been fixed there is no reason for the meta ebuild to exist at all. So just ignoring it till this bug is fixed and removing the meta ebuild afterwards seems more appealing in my opinion. We did consider this issue before writing comment 0.
This split is making my built_with_use checks really ugly... confutils_require_built_with_all =x11-libs/qt-4* gif jpeg mysql opengl \ png tiff becomes a serious explosion of checks to work with <qt-4.4 and >=qt-4.4. Any suggestions on making this nicer are welcome

Any > suggestions on making this nicer are welcome After comment #7 QT4_BUILT_WITH_USE_CHECK="gif jpeg mysql opengl png tiff" should handle this properly for both monolithic and split packages as long as you take care of setting the dependencies properly. gif, jpeg, png and tiff will pull in qt-gui. mysql will pull in qt-sql and opengl will pull in qt-opengl. Reading the new qt4_monolithic_to_split_flag() function would tell you this.
Chipping in here, as the whole repository is broken wrt. Qt 4.4, even in the cases ebuilds are using split ebuilds (incorrectly). Beforehand: Relying on best_version() or the broken qt4_min_version() stuff from qt4.eclass is not fine. - Migrating existing ebuilds requires a dependency like || ( ( splitQt1 .. splitQtN ) <x11-libs/qt-4.4:4 ) For x11-libs/qt any dependency atom _not_ including version 4.4 is fine. It is a requirement¹ to list the split Qt ebuilds first. - When Qt 4.4 is in testing, new ebuilds to be added to the tree may not include x11-libs/qt. Depend on the split ebuilds only. - For all ebuilds which are not tested or supposed to work with split Qt 4.4 ebuilds change the dependency to <x11-libs/qt-4.4:4 or a comparable dependency atom, please. The split Qt ebuilds are: x11-libs/qt-assistant x11-libs/qt-core x11-libs/qt-dbus x11-libs/qt-demo x11-libs/qt-embedded x11-libs/qt-gui x11-libs/qt-opengl x11-libs/qt-phonon x11-libs/qt-qt3support x11-libs/qt-script x11-libs/qt-sql x11-libs/qt-svg x11-libs/qt-test x11-libs/qt-webkit x11-libs/qt-xmlpatterns [1] https://bugs.gentoo.org/show_bug.cgi?id=232246
After going through the tree and fixing existing split Qt dependencies, my script spits out these packages without any ebuild featuring split Qt ebuilds: app-backup/bacula app-crypt/ophcrack app-crypt/xca app-text/djvu dev-ada/qtada dev-java/qtjambi dev-ruby/qt4-qtruby dev-util/crossvc media-libs/amanith media-sound/mumble media-sound/murmur media-tv/mythtv net-im/skype net-irc/kvirc net-misc/vidalia net-wireless/wpa_supplicant sci-chemistry/avogadro x11-misc/qterm x11-themes/mythtv-theme
Reading changelogs telling me to come here, I fail to see why such a change is needed and why the old one is claimed as broken: -COMMONDEPEND="|| ( ( x11-libs/qt-gui x11-libs/qt-core ) >=x11-libs/qt-4.2.0:4 ) +COMMONDEPEND="|| ( ( x11-libs/qt-gui x11-libs/qt-core ) =x11-libs/qt-4.3*:4 ) Please fix your scripts or try to rethink about it, because in both cases of the || there would have been enough deps installed.
