Re: [Swig-user] interesting SWIG parsing corner case

[Paul O. <pa...@po...>]

Hi speedy,

I had a similar problem when trying to wrap the Cg library for Tcl3D.

cg.h has lots of definitions like follows:

typedef enum
  {
# define CG_ENUM_MACRO(enum_name, enum_val) \
    enum_name = enum_val,
# include <Cg/cg_enums.h>
  } CGenum;


I used the C preprocessor to resolve the "includes" and let swig
parse the preprocessor output stored in cgExpanded.h:

cgExpanded.h: Cg/cg.h
	$(CC) $(CFLAGS) -E $< > $@



See www.tcl3d.org for the sources (subdirectory tcl3dCg).


Greetings,

Paul
