RE: toLua gives syntax errors

["Andrew Yount" <ayount@...>]

The code you show as being in class1_lua.h should be in a CPP file.  

The contents of my generated toLua header:
------------------------------------------------------------------------
--
/*
** Lua binding: gameplay
** Generated automatically by tolua++-1.0.92.
*/

/* Exported function */
TOLUA_API int  tolua_gameplay_open (lua_State* tolua_S);

------------------------------------------------------------------------
--

That's it.  The rest of the generated code goes in the CPP.  Perhaps
you're misusing the command line params?  My command line (all one line,
its just long):

tolua++ -o lua_gameplay_methods_generated.cpp -n gameplay -H
lua_gameplay_methods_generated.h lua_gameplay_methods.pkg

Hello everyone!

OK, I used these commands:

tolua++ class1.h >> class1.pkg
tolua++ -o class1_Lua.h class1.pkg
g++ main.cpp class1.cpp -ltolua++

GCC gives me this BS:
-----------------------------
In file included from main.cpp:6:
class1_Lua.h: In function `int 
tolua_class1_tolua_class1_open00(lua_State*)':
class1_Lua.h:37: error: `tolua_ret' has both `extern' and initializer
class1_Lua.h:37: error: expected primary-expression before "extern"

tolua_class1_tolua_class1_open01(lua_State*)':

class1_Lua.h:115: error: expected primary-expression before "extern"
class1_Lua.h:115: error: expected `)' before "extern"
-----------------------------

Did I do something wrong? Here's my files:

main.cpp:
-----------------------------
#include <tolua++.h>

#include "class1_Lua.h"

int main()
{
}

-----------------------------


class1.cpp:
-----------------------------
#include "class1.h"

void Class1::AddOne()
{
	++num;
}

-----------------------------


class1.h:
-----------------------------
#ifndef CLASS1
#define CLASS1

class Class1
{
	int num;
	
	public:
		void AddOne();
};

#endif // CLASS1

-----------------------------

And here's the faulty one, class1_Lua.h:
-----------------------------
/*
** Lua binding: class1
** Generated automatically by tolua++-1.0.92 on 06/20/07 06:04:29.

Anyone know what the problem is? Thanks! (And sorry for the long
message...)
