[GRASS-dev] trying to compile wxPython NVIZ

[William Kyngesburye]

I got further now.  By ignoring render.c, libnviz compiles.

Now I'm in wxpython/nviz.  I see that there is still the nviz header  
include order problem here.  In wxpython nviz.h, the order should be:

extern "C" {
#include <grass/gis.h>
#include <grass/nviz.h>
#include <grass/gsurf.h>
#include <grass/gstypes.h>
}


And I see one in nviz.i:

%{
#include "nviz.h"
#include <grass/gsurf.h>
#include <grass/gstypes.h>
%}


Now I get an error in the swig wrapper:

make: *** [OBJ.i386-apple-darwin9.3.0/grass7_wxnviz_wrap.o] Error 1

The relevant lines (first case):

   template <class Type>
   struct traits_check<Type, value_category> {
     static bool check(PyObject *obj) {
       int res = obj ? asval(obj, (Type *)(0)) : SWIG_ERROR;
       return SWIG_IsOK(res) ? true : false;
     }
   };

It's the check(PyObject) line.  All the other errors are also on  
check(PyObject) lines (except that last one), which is:

	    return pyseq.check() ? SWIG_OK : SWIG_ERROR;

I'm using the SWIG included in OSX Xcode 3.1: v1.3.31.
