Something weird happened (LUA 5.1)

[BoingBoing]

Using Visual C++ 2005 Express Edition:

Well I compiled with Lua 5.1 before, and I could compile one of my old projects just fine.

I decided to put the same files into the Source engine. Well it compiled fine, right up to:

Well, I tried recompiling that old project. Same errors. What the fudge?

Then I just thought Microsoft fudged up. And it probably did.
I opened the project into CODE::BLOCKS and converted and everything, it compiles FINE.
I opened up Source and Source is apparently not compatible with CODE::BLOCKS at all. Any ideas?

[Chandler]

You added the lua.c and (i'm guessing) luac.c

These contain main functions and should not be used with the Source Engine.

[BoingBoing]

I removed luac.c (Because as I already told you, I had another project before that uses lua. I'm not stupid.)

Do I have to remove lua.c?

Edit: Removed lua.c, it apparently depends on it and still tries to compile it.

[Deco Da Man]

You only need to include lua.h and link with lua5.1.lib . You then put lua5.1.dll in the same directory as hl2.exe (or whatever) and it'll find it.

Well then get rid of it, there's not such thing as "depends on it" unless you don't get rid of it.
