This disables propagated of Qt 5 build inputs at the request of
@edolstra. If this breaks your build, you need to add the missing
dependencies yourself. If this breaks your package at runtime, you need
to wrap your package to set either the plugin path or the QML import
path.
This commit also removes the 5.2 branch in favor of 5.3. Several
components of KDE5 require Qt 5.3, so it doesn't make much sense to have
the rest of the system on an older version. Also, the application styles
may not be compatible because Qt breaks ABI compatibility between versions.
Qt5 currently hardcodes /usr/{share,lib}/X11/locale/. Fix it to use
paths from the nix store. Qt4 is unaffected.
This fixes a startup warning for applications built with qt5 (e.g.
qtcreator, shotcut):
Qt Warning: Could not find a location of the system's Compose files. Consider setting the QTCOMPOSE environment variable.
The file $out/mkspecs/qconfig.pri contains a list of all include /
library paths used during the build, including build-time-only
packages like GDB and Ruby. So get rid of those.
Building the tests (which as far as I can tell we don't even run)
makes the build take > 19 GiB of disk space, which is a bit
excessive. Without the tests, it takes 2.6 GiB.
Consider this as a first step towards the integration of Qt5 into nixpkgs,
it does not yet intends to replace Qt4 on every packages even if possible.
My goal here is to have a first derivation in common between people who
needs qt5 for development purposes.
The derivation has been written from scratch but I took care to read at the
version 4 to re-integrate some patches which are still compatible. However,
I did not had enough time to test gtkStyle and flashplayerFix as I do not
use any of them. Also, OSX users will have to do some extra work because
I do not have any mac.
Finally, as some configure flags have changed and in an hope to provide a
clear package definition before it becomes mature, I voluntary added some
flags which are default. Once every option will be mastered, we will just
have to redo a pass on qt5 configure flags and remove the ones which are
set by default.
