Does anyone have fltk 1.1.x or 1.2 bindings working with OS X?
The ruby-fltk site at sourceforge looks like it hasn't been
updated in about 2 years.

Hello Jim,

Does anyone have fltk 1.1.x or 1.2 bindings working with OS X?
The ruby-fltk site at sourceforge looks like it hasn't been
updated in about 2 years.

Not for OS X but i have a working ruby-fltk for WinXP/Win2K. It comes
precompiled with with IDE.

Linking ruby-fltk-0.9.0 against fltk-1.1.5rc1 should be okay.

I had to add a __declspec(dllexport) and change a
change a few compiler options which seems not be necessary for unix based os.

I have compiled 1.1.5rc1 and have downloaded ruby-fltk-0.9.0.
Compiling ruby-fltk gives the error:

In file included from flimage.cc:6:
flimage.h: In constructor `RBFLImage::RBFLImage(int, int, int)':
flimage.h:44: error: no matching function for call to
`Fl_Image::Fl_Image(int&, int&)'
/opt/local/include/FL/Fl_Image.H:64: error: candidates are:
  Fl_Image::Fl_Image(int, int, int)
/opt/local/include/FL/Fl_Image.H:41: error:

Looking at this further, extconf.rb checks the number of args
to Fl_Image. It has three in the .H file, but for some reason
the test code won't build:

  jdf@cheetah 26 /Users/jdf/tmp/fltest % cat flimage3.cc
  #include <FL/Fl_Image.H>
  int main(){
    Fl_Image *img = new Fl_Image(0,0,0);
    return 0;
  }

  jdf@cheetah 27 /Users/jdf/tmp/fltest % gcc flimage3.cc
  ld: Undefined symbols:
  vtable for Fl_Image
  operator delete(void*)
  operator new(unsigned long)
  ___gxx_personality_v0

A witty saying proves nothing, but saying something pointless gets
people's attention.

jdf@cheetah 27 /Users/jdf/tmp/fltest % gcc flimage3.cc
ld: Undefined symbols:

g++ -I/opt/local/include -L/opt/local/lib flimage3.cc
ld: Undefined symbols:
vtable for Fl_Image

Still fails.
