fltk, oct files, and windows

[Brian Blais]

Hello,

I am trying to get some of my fltk/octave code to run under windows.  I
can get fltk compiled under cygwin, and all of the demos work.  When I
bundle the functions in an oct file, the code freezes.  I am attaching
the code, which is just to open up a window with a message, and an ok
button. I call it with something like:

fltest('hello');

The code runs, puts the window up, but then never exits.  I think that 
either I am doing something stupid, or there is a conflict
in the linker/compiler flags that I am introducing somehow.  I am
compiling it with:

mkoctfile -I. `fltk-config --cxxflags`  -Wall `fltk-config --ldflags`
-lm fltest.cc

I am using octave 2.1.69, on both Linux and Windows 2000.  The same code
and compile line work in Linux.

Any ideas?


                        thanks,

                                Brian Blais
