Strange I put the zip after deleting Lua5.2 and the other luas. I'll see when I get home today.

I'm back. I got:

You appear to have Lua 5.3 (or 5.2?) headers somewhere in your include path. The guide provides the lua5.1/ folder with the 5.1 headers, but it seems you have the 5.3 headers somewhere, causing compile errors. You should find where those are and remove them.

If using Lua 5.2, I think (?) you need to define LUA_COMPAT_ALL. But you should just try to use the 5.1 the guide provides.

player4444

Quick question: Does each LUA (ex. 5.1, 5.2) have different syntax rules like python(ex. 2.7, 3.6)?

edit: Odd, I deleted all LUA, including 5.1, and reinstalled it, and still get this, it may be in another path.

2nd edit: Let me check variables.

There's some functions added, and some functions removed / deprecated in later version. This applies both to the language, and to the C api. You're having difficulties with the C api changing. TPT can only be compiled with 5.1 or 5.2, not 5.3.

Most / all TPT scripts won't break with 5.1, they should work fine.

Edit: don't "install" lua. Just follow the guide, all you have to do is copy the lib/ and include/ folders into C:\MinGW
I recommend deleting all "installed" Luas unless you need them for something else.

player4444

Sorry, I by "install" I mean copy them into the folders.

The only other thing I can think of, if C:\MinGW isn't your MinGW install directory you may have to put it somewhere else.

Have you considered the visual studio guide? It's more supported than MinGW. I want to support MinGW again but I haven't had time to redo the guide.

God damn it, I was looking in Python27, not MINGW, that was the problem. BUT I KEEP GETTING ERRORS ;-;

Edit: From working with C in past, I'm going to try to change the " " to <>

Edit 2: Wait I think theres suppossed to be a Lua headder in that directory, Imma check the TPT Source Code.

" " and < > are irrelevant. They are just used to make it clearer if it's from a standard library or your own project.

Anyway, now it sounds like you deleted lua :P. So now it can't find the headers at all. You'll need to copy them into that folder again.

Edit:
Can you connect to IRC?
Here's a guide: https://powdertoy.co.uk/Wiki/W/Irc_setup.html
If you don't want to bother installing a client, use the Freenode webchat link.
It will help this go a lot faster.

I've reinstalled MINGW and now I get the error:

c:/mingw/bin/../lib/gcc/mingw32/6.3.0/../../../../mingw32/bin/ld.exe: cannot find -llua

Error while trying to compile with scons
