I have just started to work with LUA (which is a scripting library) and it seems really easy and powerful to use so I'm planning to do almost all my game code using it to communicate with my engine, the problem is that my program won't compile when I call a LUA function. It doesn't bother about the library being added or header file included but when I call a function it complains that things have already been defined in mscvt.dll and libc.dll (i think these are the names, I'm not at home to check). I have changed linker options (I admit I don't fully know what I'm doing with these options) and it either generates new errors or gives the same result. It is a dos program and I use sdl, OGL, FMOD also the compiler is Visual C 6. Hope someone can help. [edited by - JinJo on May 26, 2004 7:43:09 PM]

make sure ALL the libs you compile in are using the same runtime library, otherwise thats when problems accure such as you have.
I cant remember where the runtime library option is under VC6 however :|

I still can''t get lua to compile, i get these errors:
