There seem to be syntax differences. I just updated and built csound5 from
current CVS, and I can run ./csound examples/fl.csd (another widget
example) just fine.

Subject: [CSOUND-DEV:4622] FLTK in csound5 and csoundAV


Hi,
With my new realtime csound5 *grin* I tested a CsoundAV widget csd, but
even 
though no error is produced and sound comes out, no widgets window is
created.
FLTK is working becuse I see the window with the ftable. Are there
differences 
in usage of FLTK in csound5?
Do I need to add a flag to enable FLTK?
The csd from Gabriel's examples:

giving it a frequency of 150 cps",  150,150, 1,300,50,50,20,    0,1,0,3

Hi Michael,
I don't know if you changed something, but I rebuilt Csound5 with your recent 
changes (and after unsuccesfully trying to build with portaudio asio), and 
FLTK worked just fine with Gabriel's example!
SO I guess apart from the underscores in opcodes like FLpanel_end and such, 
there is no apparent difference with CsoundAV.
Cheers,
Andres
