[texworks] Compiling on windows with Mingw

[Stefan Löffler]

Hi,

it's great that the building process works now. There's still the issue
with manually tampering with the Makefiles, though, which I'd like to
resolve before updating the guide.

Yeah, you're essentially right. They refer to header files (though they
don't have any extension; but then again they include the correct
(platform dependent?) .h files).

OK. Actually, I consider this a Qt/KDE bug. Normally, qmake should
produce valid Makefiles. Anyway, we have to work around this somehow for
the time being. I see several possibility for this:
1) Change the LIBS line in Makefile.Release, as you did. The problem I
have with this is that the Makefile gets generated (and hence
overwritten) automatically
2) Rename the files in %KDE%\libs. Not ideal, either, since they may
have some reason for naming the things the way they do. Besides, this
might break other builds...
3) Going with the "QT = " line and including the include paths manually.
This would make qmake essentially useless, though.
4) Try adding the following two lines instead of the previously
suggested workaround:
    LIBS -= -lQtScript
    LIBS += -lQtScript4

I favor option 4 for now. If it works, it would probably be the most
elegant workaround. If this doesn't work, we may have to return to the
"QT =" solution, although my last approach was a bit extreme (after all
it's only the QtScript part that causes trouble, IIRC).

Cheers,
