Question

I am trying to building my project using waf.The Project is complied properly but there is some link error.Its fails to link to with the Resources file (.qrc file)

main.cpp.1.o: In function main':
/home/sobingt/project/masterdetail/build/../main.cpp:20: undefined reference
toqInitResources_masterdetail()’

WAF output –zones=deps

I know it must be a stupid mistake.Please help. Link to Question posted in qtcentre

Solution i am trying out now:
I am running moc on all headers (or source) file containing a Q_OBJECT macro.

 moc -o moc_something.cpp something.h

and then the moc_something.cpp is added to the sources being built.

I am trying for resource compiler:

 rcc -o masterdetail.cpp masterdetail.qrc

and then the masterdetail.cpp has to be added to the sources being built.

I think the above is done by the qmake automatically..i am compiling it manually to try to find a proper solution

Answer 1

It seems waf is not collecting moc files. According with waf docs, try adding something like this:

from waflib.TaskGen import feature, before_method, after_method

@feature('cxx')
@after_method('process_source')
@before_method('apply_incpaths')
def add_includes_paths(self):
        incs = set(self.to_list(getattr(self, 'includes', '')))
        for x in self.compiled_tasks:
                incs.add(x.inputs[0].parent.path_from(self.path))
        self.includes = list(incs)

process_source should take care of the moc files processing
