[Discuss-gnuradio] gr-qtgui working?

[Michael Dickens]

I'm trying to get 'gr-qtgui' to work on OSX (10.4, but doesn't really  
matter), and have finally figured out that I need QT 3 (not 4, at  
least on OSX the way QT4 gets installed, even though the .m4 script  
looks for >= 3.3) and QWT 4 or 5 paired with it (qwt 5.0.2 is the  
latest, so I'm using that).  I have to set QWT_CFLAGS, but that's  
pretty simple to deal with.  Now that I have QT and QWT, correct  
versions, installed, doing "make" in that module results in:

The 'Carbon' and related stuff comes from the qt.pc pkg-config file,  
which looks OK when editing under Emacs (no strange characters).  All  
of the above looks OK to me ... but clearly it doesn't compile  
cleanly on OSX.  And I assume it's an OSX issue?  I haven't tried  
this on Linux yet.

Is anyone still maintaining this module?  What's up with the  
#warning's?  Unfinished code?  It looks like the latest significant  
change was in March'07.

Is QWT/QT better for going graphics than WX?  Being an OSX user, I  
prefer Aqua-native if at all possible, but since that requires it's  
own OSX specific module and coding which would take significant time  
on my part, that's probably not going to happen.  Thus looking at a  
more OS-neutral alternative: tk, qwt/qt, wx, whatever ...  I have  
experience with WX only because of GNU Radio, but I have no  
experience with the others.
