unresolved external symbol "int __cdecl luaopen_socket_core(struct lua_State *)"

[HODAKdev]

Hi, I'm trying to add a LuaSocket to my project but it looks like .lib is ignoring it.

#pragma comment(lib, "single.lib")
#include <luasocket.h>
int main(void) {
	luaopen_socket_core(NULL);
}

I use Windows and the compiler from MSVC Compiler, I also tried to compile without .dll just .lib, but nothing. Can anyone help me?

I'm sorry I am not on nor even have access to a Windows machine to test this on. There are Windows users out there so maybe somebody will chime in.

If you do figure out what is wrong and anything needs fixing in the project itself we're open to contributions!

This

(?luaopen_socket_core@@YAHPEAUlua_State@@@Z)

looks like the compiler/linker is expecting a name-mangled (i.e. C++) symbol. There's probably a extern "C" { ... } missing around the LuaSocket include (or a commandline flag to force plain C compilation).

Btw., this

luaopen_socket_core(NULL);

will crash horribly. Also, IIRC, the luaopen_* functions are supposed to be lua_called.
