Qt project, no rule to make target needed by

Question

I have a problem with my Makefile. I downloaded opensource Qt project. Hence, when I try to compile it I got a message:

error: No rule to make target needed by stop.

In my .pro file I have relative paths to *.cpp files. So when I replace relative paths to absolute it works, another case it got me with the error above. System is Linux.

What should I do to do this work with the relative paths?

Answer 1

I would use QtCreator, opening the project and then adding one of the misplaced sources (let say the first you see in .pro).

The IDE should place it with the correct relative path, as appropriate per your folder choice. After that cut'n'paste the path prefix all over the remaining places.

Anyway, path prefixes should be relative to the directory where you find the .pro. An example from an opensource project I'm using (QZXIng, a Qt port of ZXing):

SOURCES += CameraImageWrapper.cpp \
    QZXing.cpp \
    imagehandler.cpp \
    zxing/ResultPointCallback.cpp \
    zxing/ResultPoint.cpp \
    zxing/Result.cpp \
    ...

so you could try to move the .pro file where appropriate instead of changing relative paths...

One reason for this issue is because you have removed a file which you no longer need but forgot remove from res.qrc
