Re: Where in the boost.build code are the files actually compiled? (Newbie)

Ok I think I understand that now. Thanks.

So basically I have to change where this target's action is setup so
that when it calls the 'moc' action in tools/qt.jam it passes the
right name to the action. Any idea where I should look to find this?
I'm guessing it's somewhere in the qt module definition where it says:

generators.register-standard qt.moc : H : CPP(moc_%) : <allow>qt ;

But I'm not really sure what teh 'CPP(moc_%)' syntax means.

Thanks again for your help,
