Hi guys,
I'm having some trouble loading a c++ library with loadlib. Suppose I
have a file lfoo.cc:
extern "C"
{
#include <lua.h>
#include <lauxlib.h>
#include <lualib.h>
}
#include <iostream>
static int foo(lua_State *L)
{
std::cout << "ok!" << std::endl;
lua_pushnumber(L, 1);
return 1;
}
static const luaL_reg foolib[] = {
{"foo", foo},
{NULL, NULL}
};
LUALIB_API int foo_open_lib (lua_State *L)
{
luaL_openlib(L, "Foo", foolib, 0);
return 1;
}
This compiles with no errors nor warnings under:
g++ -W -Wall -fPIC -c lfoo.cc -o lfoo.o
g++ -W -Wall -shared -ldl -llua -llualib -o lfoo.so lfoo.o
But loadlib(path .. '/lfoo.so', 'foo_open_lib') returns nil.
Is there anything wrong?
Thanks,
Luis.
