Never had a problem.

This no longer works is 5.2 because in 5.1 luaL_register called

(the undocumented and badly named) luaL_findtable which did that magic,

but 5.2 lacks luaL_findtable.

If you want to keep this way of registering your libraries is 5.2,

but don't want to use or require LUA_COMPAT_MODULE when build Lua,

you can copy luaL_findtable from the 5.2 source and use this version

of luaL_register:

void luaL_register(lua_State *L, const char *libname, const luaL_Reg *l) {

lua_pushglobaltable(L);

luaL_findtable(L,-1,libname,0);

luaL_setfuncs(L,l,0);

}

The findtable call does not exists. I have include the files

#include <lua.h>

#include <lauxlib.h>

#include <lualib.h>

Do I have forgot an include? I'm using Lua 5.2.1

Thanks

of luaL_register:

You will find it in lauxlib.c line 764 guarded by a LUA_COMPAT_MODULE macro.

Which version is the newer calls for 5.2 without the macro?

At the moment I use

lua_pushglobaltable( m_lua );

//luaL_findtable( m_lua, -1, p_libname.c_str(), 0 );

luaL_setfuncs( m_lua, &l_functions[0], 0);

l_functions is a vector of luaL_Reg elements and the terminator item. I need to set up

a "name" for my global table

Thanks
