Description Kevin Kofler 2007-03-03 23:00:26 EST
Description of problem:
When called with a full path (bypassing the wrapper in /usr/bin which sets 
PATH), qdbuscpp2xml tries to run moc from the PATH and gets the Qt 3 one, 
resulting in an unusable D-Bus XML IDL file. This affects CMake, which calls 
the Qt tools with a full path. My KDE 4 packages currently have a workaround 
for that. However, there's a patch in qt-copy:
http://websvn.kde.org/trunk/qt-copy/patches/0154-qdbuscpp2xml-moc_path.diff?revision=616041&view=markup
which fixes qdbuscpp2xml so that, if it was called with a full path, it will 
also invoke moc with the same full path, obviating the workaround.

Version-Release number of selected component (if applicable):
qt4-4.2.2-1.fc6

How reproducible:
Always

Steps to Reproduce:
1. Try building KDE 3.80.x without playing with the PATH.
  
Actual results:
The build fails because unusable D-Bus XML files are generated by 
qdbuscpp2xml, which then produce unusable C++ files (for the adaptors) after 
qdbusxml2cpp. These fail the build.

Expected results:
qdbuscpp2xml works.

Additional info:
Workaround: Add this to the RPM specfile for any package invoking qdbuscpp2xml 
from CMake:
# Set these here because CMake bypasses the wrappers in /usr/bin.
export QT4DIR="`/usr/bin/pkg-config --variable=prefix QtCore`"
export PATH="$QT4DIR/bin:$PATH"

The other patches in qt-copy are also worth a look:

Comment 1 Rex Dieter 2007-03-05 08:24:54 EST
Very useful.
As a matter of fact, I had been intending on reviewing all the qt-copy patches
for potential inclusion.
