QT QML resource files do not recompile after changes

Question

I\'m using QT 5.9.1 working on Mac OS. My project is mobile App with C++ logic and QML UI Layer. All QML files are included into qml.qrc file, so in my .pro file I have

Answer 1

Unfortunately, the solution given in a link provided in the comments seems to be incomplete and/or broken. But it can be done like this:

update_qml.target = qml.qrc
update_qml.commands = echo>>$${update_qml.target} # same as touch
update_qml.depends = $$files(path/to/resource/files/*, true) # recurse into subdirs
QMAKE_EXTRA_TARGETS += update_qml
PRE_TARGETDEPS += $${update_qml.target}

For those who interested in how it works, QMAKE_EXTRA_TARGETS produces the following Makefile rule:

qml.qrc: file1 file2 ...
        echo>>qml.qrc

So issuing a command make qml.qrc will update the timestamp of qml.qrc as needed. However, to save us from manual typing it every time, we also make use of PRE_TARGETDEPS which fixes the main building rule:

$(DESTDIR_TARGET): qml.qrc $(OBJECTS) and other stuff ...
        $(LINKER) flags objects and other stuff ...

So now make utility will scan the previous rule every time while building the target.
