[Swig-user] More Lua related questions

[Ervin H. <ai...@gm...>]

Hi there,

there is a library, written in C, and it has several bindings which
compiled through Swig (Python, Perl and Tcl).

I'ld like to add Lua support, but there are several errors in generated
wrapper source code:

- there included the "<string>" header, instead of "<string.h>"; here is
the context:

#define SWIG_exception(a,b)\
{ lua_pushfstring(L,"%s:%s",#a,b);SWIG_fail; }


#include <string>

typedef union {
  struct {
    float min;
    float max;
    float step;
  } n;
  struct {
    const char *combostr[8];
  } c;
} confparams_u;


- there are several undefined types in wrapper, the context:

#ifdef __cplusplus
extern "C" {
#endif
static int _wrap_std_set(lua_State* L) {
  int SWIG_arg = 0;
  namespace arg1 ;
  namespace *argp1 ;

  SWIG_check_num_args("std",1,1)
  if(!lua_isuserdata(L,1)) SWIG_fail_arg("std",1,"namespace");

  if
(!SWIG_IsOK(SWIG_ConvertPtr(L,1,(void**)&argp1,SWIGTYPE_p_namespace,0))){
    SWIG_fail_ptr("std_set",1,SWIGTYPE_p_namespace);
  }
  arg1 = *argp1;

  std = arg1;

  return SWIG_arg;

  if(0) SWIG_fail;

fail:
  lua_error(L);
  return SWIG_arg;
}

The "namespace" and "std" types are unknown.

Could anybody helps me to explain these errors?


Many thanks:
