Bug 526078

Summary: [qt overlay] dev-qt/qtcore-4.8.6 multilib wrapped headers cause qtdbus:4-dependant packages to fail to build

Patch showing the differences between headers installed with qtcore-4.8.6 pre- and post- #519110

Description Mads 2014-10-20 13:13:03 UTC
After #519110 was fixed, I noticed that packages depending on qtdbus:4 (e.g. libdbusmenu-qt-0.9.3_pre20140619 or PyQt4-4.11.2-r1) did not compile. I tracked this down to difference between some header files with qtcore-4.8.6 before and after #519110.

Reproducible: Always

Steps to Reproduce:
1. Install a recent version of qtcore-4.8.6 (after the eclass update mentioned in #519110)
2. Try to install e.g. libdbusmenu-qt-0.9.3_pre20140619

Actual Results:  
See attached build log

Expected Results:  
That packages dependent on qtdbus:4 compiles.

Build log with USE="qt4 qt5" and qmake set to /usr/lib64/qt4/qmake

Build log of libdbusmenu-qt-0.9.3_pre20140619 with USE="qt4 qt5" and qmake set to /usr/lib64/qt4/qmake. This compiled before #519110 was fixed.

Patch showing the differences between headers installed with qtcore-4.8.6 pre- and post- #519110

Patch showing the differences pre- and post- #519110. If you apply this against root after installing qtcore-4.8.6, libdbusmenu-qt will compile again.
Comment 3 Michał Górny archtester Gentoo Infrastructure gentoo-dev Security 2014-10-20 17:20:20 UTC
So most likely we're going back to the separate header directories idea?
Comment 4 Davide Pesavento gentoo-dev 2014-10-21 00:57:36 UTC
I'm afraid so... What's the suggested ABI-specific include dir?
Comment 5 Michał Górny archtester Gentoo Infrastructure gentoo-dev Security 2014-10-21 06:46:36 UTC
I'd guess /usr/$(get_libdir)/qt4/include :).
Comment 6 Michał Górny archtester Gentoo Infrastructure gentoo-dev Security 2014-10-21 10:42:02 UTC
Ok, I'm going to test how broken the alternate headerdir setup is :).
Comment 7 Davide Pesavento gentoo-dev 2014-10-22 00:21:46 UTC
Apparently wrapping qconfig.h works on fedora:

Why isn't it working for us?
Comment 8 Davide Pesavento gentoo-dev 2014-10-27 00:50:26 UTC
Ok... the sed in qtcore needs adjustments.
Comment 9 Davide Pesavento gentoo-dev 2014-10-27 00:56:04 UTC
Should be fixed now.
Comment 10 Davide Pesavento gentoo-dev 2014-10-27 00:56:49 UTC
(you have to re-emerge at least qtcore)
Comment 11 Mads 2014-10-27 08:35:10 UTC
Nice! So this means the headers are unified still?
Comment 12 Mads 2014-10-27 08:49:02 UTC
I mean, are there plans for splitting the headers anymore since this works?
Comment 13 Davide Pesavento gentoo-dev 2014-10-27 10:45:46 UTC
Only qconfig.h is wrapped now, and I do not intend to install all the headers separately unless some other insurmountable problem turns up.
