Optional lua for debugging

[CIB]

See the commit for more details.

I tested compilation with LUA=1 and without, but tests on more systems would be good. Right now the Makefile only includes support for the way things are set up on arch linux, since I have no damn clue where the lua 5.1 stuff is on other systems.

EDIT: I had planned to use CMake to get this to run on all systems easily, but it turns out the CMake lua51 include file is broken. So yeah, gonna have to fix up the Makefile with all the platforms.

Please make us a windows makefile!
I'm not a programmer and I have no idea what wizardry makes it tick but I need one to compile and test some of my stuff.
I will give you one million internets if you can get us a makefile again so I can properly test my PRs!

@Rivet-the-Zombie You should be able to compile it by setting NATIVE=win32

[CIB]

This particular PR with LUA=1 doesn't work yet on windows, but I mean to add support/instructions for it. Generally, the regular makefile should work just fine on windows, as does the cmakelists.txt

[Rivet-the-Zombie]

Anybody have any idea what's the actual command(s) to compile for Windows under MinGW using the current makefile? I really have no idea what I'm doing when it comes to the compiling stage, except for what I've picked up from guides on the forums and they're no longer really up to date about this.

@Rivet-the-Zombie Please keep issue and pull request discussions about the actual issue/pull request. Help for compiling on Windows would be best handled in IRC or on the forums.

FYI, CMake-only support isn't ok, if the main Makefile won't build it, I'm not going to land it.

Okay this is simply too useful to let rot due to percieved build 'hurdles'....thus it's fair to say help compiling is quite relevent. Mostly re; mingw building, is the official wintendo bin mingw? If so, how does it handle SDL? How is that different from msvc++? Afaik mingw build will work with a liblua.a and lua headers thrown in right where sdl is...neh?

[kevingranade]

Doesn't build on Fedora and I have no idea how to make it so.

[atomicdryad]

...build error?
output of rpm -qla '_lua_devel*' ?

[CIB]

Yeah, the easiest would probably be to find another Makefile that includes lua5.1 and check how they're handling cross-platform problems.

[CIB]

Okay, other than the MinGW build guide that I still need to finish(http://www.wiki.cataclysmdda.com/index.php?title=How_to_compile#MinGW_with_MSYS), this should now build on most unix-likes and windows. No idea about OS X, though I hear pkg-config exists for that as well, so it should work(after installing pkg-config and lua5.1).

[kevingranade]

pkg-config on my system seems to want "lua" instead of "lua5.1", so sure if that's resolvable.
also after adjusting that and compiling I get this on startup:
DEBUG: Error in lua module: cannot open data/main.lua: No such file or directory

[vache]

I was able to compile and test a few lua commands on Debian
