fltk on OS X working?

[Jim Freeze]

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)':

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

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

Try
g++ flimage3.cc

 

[Jim Freeze]

Try
g++ flimage3.cc

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

Still fails.
