Qmake custom compilers: how to process generated header files with moc

jonjonas68

I've a code generator which generates QObject based classes,
to use it with qmake I defined a custom compiler (see below).
Both files were generated correctly, but my problem is, the generated header file should be processed by the moc compiler.
I cannot figure out how to do this.
If I try the undocumented config option moc_verify no header files will be generated at all.

Does anyone know a solution, or is this impossible?

gen_h.name = generator custom compiler - ${QMAKE_FILE_IN}
gen_h.input = GEN_INPUT
gen_h.output = ${QMAKE_FILE_BASE}.h
gen_h.commands = generator ${QMAKE_FILE_NAME} --outputheader ${QMAKE_FILE_OUT}
gen_h.CONFIG += target_predeps
gen_h.dependency_type = TYPE_C
gen_h.variable_out = HEADERS
QMAKE_EXTRA_COMPILERS += gen_h

gen_cpp.name = generator custom compiler - ${QMAKE_FILE_IN}
gen_cpp.input = GEN_INPUT
gen_cpp.output = ${QMAKE_FILE_BASE}.cpp
gen_cpp.commands = generator ${QMAKE_FILE_NAME} --outputimplementation ${QMAKE_FILE_OUT} --include ${QMAKE_FILE_BASE}.h
gen_cpp.CONFIG += target_predeps
gen_cpp.dependency_type = TYPE_C
gen_cpp.variable_out = GENERATED_SOURCES
QMAKE_EXTRA_COMPILERS += gen_cpp

I have the same issue.
Any idea ?

From the digia support I've heard, that I should add moc_verify to the CONFIG of the custom compiler.

gen_cpp.CONFIG += target_predeps moc_verify

They send me a simple example where it works, but for my concrete pro files it doesn't work.

So they send me a patch for qmake, which also doesn't help,
so I'm stuck with this.

       // If it does not exist we assume it will be mocable for now

Thanks for response,

I did not have no more success with this.

I'm still searching for a solution.
