Running the generator on Linux
Message 1 in thread
Hello!
I've tried to run the generator_example.sh on Crux 2.2, after first
having installed Qt4 successfully.
However, I get this printout on screen:
# generator_example.sh
Running generator
Generator requires QTDIR to be set
Preprocessor failed on file: 'mywidget.h'

I did set the QTDIR variable to /usr/lib/qt.

Hi Helge,
The exact lines that fail in the generator are:
QString qtdir = getenv ("QTDIR");
if (qtdir.isEmpty()) {
fprintf(stderr, "Generator requires QTDIR to be set\n");
return false;
}
I don't see how this can fail in any other case than if you failed to
set your QTDIR variable. If you do "env" in the shell it contains QTDIR?

Correcting that, getting me a bit further. Where should qt_config be
located?

Its located in $QTDIR/mkspecs/features/qt_config.pri
Is this a "make installed" version of Qt 4?

This is unsettling indeed...
Your $QTDIR/include does contain QtGui/qwidget.h and friends, I suppose?

Message 5 in thread
Hmm, seems like my Crux distro has spread things all around.
I have mkspecs installed under /usr/share/qt, qwidget.h under
/usr/include/qt, executables under /usr/bin and libraries under
/usr/lib/qt....
This setup is intuitive to me, but it seems that the generator expects
all Qt stuff to be located in one place only?
Any way to hack around this with the generator, or should I download the
Qt tar ball and build/install without the
crux package regime? No big deal, but some finer control would have been
nice though...
Regards,
Helge

qt_config is loaded by qmake, regardless of the qtjambi generator so
this should be happening for all your projects then, which indicates
that your Qt installation is not working properly.
Also, Qt expects qwidget.h to be located in
$QTDIR/include/QtGui/qwidget.h. This is what should happen if you do a
make install of a source package at least.
Basing Qt Jambi on a proper Qt package would probably solve all these
problems.
