Compiling Luasocket

Question

So I'm trying to use Luasocket with a third-party game that has a Lua API. It has support for packages but it says it needs some luasocket files I don't have (though it works outside of the IDE because I have Luasocket installed in the lua directory). These seem to be core.dll, core.lua and core/init.lua. I assume I get these by compiling Luasocket.

I tried that with very little success. The scripts for building luasocket that I find always give me errors. How am I supposed to get these files and compile them?

EDIT: Here is the error Cygwin gives me when I try to build Luasocket:

Error: failed to build LuaSocket

Can you not just use the copies you already have installed by putting them where the game is looking for them? — Etan Reisner, Jan 13 '15 at 20:59
I tried that, but a) it requests files that I can't find in the installation, and b) I think they're of a different version (I have an older version of Luasocket I believe) or something, because the server crashes when I add core.dll where it is requested. Either way, I'd like to compile Luasocket just to explore all avenues — lordnoob, Jan 13 '15 at 21:08
What files can't you find? What version do you have? The version of luasocket itself likely matters less than the version of lua the application is expecting (and the version of lua that luasocket was built for). — Etan Reisner, Jan 13 '15 at 21:14
The application expects files for lua 5.2. I got the latest one from Github (luasocket 3.0-rc1), however the files I gave it are for 2.0.2, the version of LuaSocket that came with Lua For Windows. I would gladly compile the newer ones, but trying to gives me the above error (and using the old core.dll makes the game crash). And so, this is my question. **How can I compile it**? LuaRocks also gives me an error. Unfortunately, this release of LuaSocket is, according to the changelog, the one that added Lua 5.2 compatibility, which the app uses, so I have to use it. Thanks in advance — lordnoob, Jan 13 '15 at 21:31
I could see how that could lead to problems. The LuaSocket that comes with LFW is likely for Lua 5.1. That means when you load that `core.dll` it's also going to try and pull `lua51.dll`into the running process which means you end up with both `lua52.dll` and `lua51.dll` getting mixed together. — greatwolf, Jan 13 '15 at 22:38

This SO answer may help. It provides details on how to compile using gcc as well as references to build scripts I use and compiled binaries for luasocket 3.0-rc1 and Lua 5.2.
