Thanks for your answer.
BTW, have you ever mixed cpp files with m files in the same .pro file?
I have such a case, and the xcodeproj file give an error about the "Qt Preprocessors" script (something related to "No rule to make target '../folder/myfile.h' ").
The error in xcodeproj looks like this:
c -D_DEBUG -DUNICODE ... -I/usr/llocal/Qt4.6/....
Make: c: No such file or directory
Does this mean something for you?
Thanks.
