Bug#418832: Build fails in Qt 4.2.1 due to known bug
Package: libqt4-core
Version: 4.2.1-2+b1
My application fails to build when the QT_NO_DEBUG_OUTPUT define is
made. This was a known bug in Qt 4.2 which was fixed in v4.2.2; see
this Trolltech tracker issue:
http://www.trolltech.com/developer/task-tracker/index_html?method=entry&id=133796
Build fails with errors like these (I use CMake for configure, hence the
output style):
[ 54%] Building CXX object CMakeFiles/qtm.dir/catkin.o
/usr/include/qt4/QtCore/qglobal.h:1250: error: expected unqualified-id
before ‘if’
/usr/include/qt4/QtCore/qglobal.h:1250: error: expected unqualified-id
before ‘else’
make[2]: *** [CMakeFiles/qtm.dir/catkin.o] Error 1
make[1]: *** [CMakeFiles/qtm.dir/all] Error 2
make: *** [all] Error 2
I use this macro to control my own debug output, not just to suppress
Qt's own.
I would add that the latest patch release (4.2.3) fixes a bug which
causes the scroll bar to fail to appear in QTextEdit widgets when text
starts to go beyond the widget's size. This is important to me as my
application uses that class heavily. I suggest that Qt 4 be updated at
least to version 4.2.2.
I am using Debian Etch, kernel 2.6.18-4-686, libc6 v2.3.6.ds1-13.
