If I open the .pro file via left click in Qt Creator, this happens:
build results in an error, so I have to qmake
then I get 22 errors with "gl* (glVertexAttribPointer etc.) was not declared" if I build or "gst/interfaces/photography.h: No such file or directory" if I rebuild

If I delete everything, unzip it again, open QtCreator manually and load the same .pro file via menu, it buils just fine, but if I change it into a format to be able to generate a Debian package easily later on I get "No rule to make target 'texture.qrc'"

Could anybody help me with this please? I seem not to be sufficiently familiar with qmake.

Oh - if I try to run it using MADDE (which again works fine with other programs), I get:
Code:
Files to deploy: /scratchbox/users/maemo/home/maemo/OwnProjects/AWESOME/DistanceQT-build/DistanceQT.
Deployment finished.
Starting remote application.
chmod u+x /home/developer/DistanceQT; source /etc/profile;  /h ome/developer/DistanceQT  
Pipline initialized! 
GST error: v4l2camsrc_calls.c(686): gst_v4l2camsrc_open (): /GstPipeline:test-camera/GstV4l2CamSrc:camera_src: 
system error: Permission denied 
Aborted
Since this is for educational purposes: Could anybody show how to integrate OpenCV? That would be awesome. Developing for the N900 is really cumbersome. I've been looking into it for weeks now and I'm still struggling with beginner mistakes, whereas I could already have written a whole enterprise application for Android in the same time.

If I build another modification compilation works, but I get a
Code:
/scratchbox/tools/bin/misc_runner: /targets/links/scratchbox.config: No such file or directory
if I try to run it via ssh. And we're talking about minor changes - changing some array values. Why does so much happen if I don't really change anything?!

Btw: I use Qt 4.6.2 instead of 4.5. If there are any cleaned up versions, fixes for my problems, updates etc please let me know.

Best regards,
Dorfmeister
