qt4-x11: FTBFS on arm (cannot bind packed field)
Package: qt4-x11
Severity: important
Tags: patch
Currently, qt4-x11 fails to build from source on arm, with this error:
In member function 'ushort& QChar::unicode()':
/build/buildd/qt4-x11-4.0.0/include/QtCore/../../src/corelib/tools/qchar.h:225:
error: cannot bind packed field '((QChar*)this)->QChar::ucs' to
'ushort&'
The full log is here:
http://buildd.debian.org/fetch.php?&pkg=qt4-x11&ver=4.0.1-5&arch=arm&stamp=1132352199&file=log&as=raw
I noticed there is a patch in the Debian version of qt-x11-free
(10_arm_gcc4.dpatch) that seems to address the same issue. The attached
patch should hopefully do the trick (I haven't been able to check for
myself as I couldn't find a Debian/arm machine with chroots that is up).
Cheers,
Jeremy
