In fact it needs 2 changes in vrml_board to be compiled on mingw (I
exactly use TDM-GCC-32, with differs slightly from mingw 4.7, and uses
gcc 4.8.1)
1 - in void SetGLError( GLenum errno ), errno collides a define in some
mingw header. So change all occurrences of errno to something like error_id
2 - the callback functions like:
void vrml_tess_begin( GLenum cmd, void* user_data )
are incorrectly defined.
they must use the CALLBACK type modifier
(see for instance 3d_basic_functions.cpp):
static void CALLBACK vrml_tess_begin( GLenum cmd, void* user_data )
I included fctsys.h to define CALLBACK (defined in a mingw include file)
#include <fctsys.h>
I changed them to:
#ifndef CALLBACK
#define CALLBACK // On linux, CALLBACK is not used, and not defined
#endif
#define GLCALLBACK(x) (( void (CALLBACK*)() )&(x))
static void CALLBACK vrml_tess_begin( GLenum cmd, void* user_data )
{
VRML_LAYER* lp = (VRML_LAYER*) user_data;
lp->glStart( cmd );
}
and later for each callback function:
// set up the tesselator callbacks
gluTessCallback( tess, GLU_TESS_BEGIN_DATA, GLCALLBACK(vrml_tess_begin) );
After that, all works fine for me.
I suggest you to add holes defined by the board outlines.
If you are using:
BOARD::GetBoardPolygonOutlines() returns the external outline polygon,
and a separate list of holes (polygons)
(see 3d_draw.cpp)
Thanks.
