LUA Information

MatrixCubed · 2002-10-31T01:09:18

Hello all, I'm hunting for some information on LUA (http://www.lua.org/). Right now my problem is in the initial stage: linker errors when calling any function (unresolved external functions). #include <stdio.h> #include <lua.h> /////////////////////////////////////////////////////////////////////////////// #pragma comment(lib, "lualib.lib") #pragma comment(lib, "lua.lib") /////////////////////////////////////////////////////////////////////////////// int main(int argc, char** argv) { lua_State* lState = NULL; lState = lua_open(100); lua_close(lState); return 0; } /////////////////////////////////////////////////////////////////////////////// I'm using the Win32 binary distribution of version 4 in VC6. Libs and headers are included in the correct locations. I'm assuming I'll have to compile the lib files and hope this works? --------------------Configuration: LUA_Test00 - Win32 Debug-------------------- Linking... Main.obj : error LNK2001: unresolved external symbol "void __cdecl lua_close(struct lua_State *)" (?lua_close@@YAXPAUlua_State@@@Z) Main.obj : error LNK2001: unresolved external symbol "struct lua_State * __cdecl lua_open(int)" (?lua_open@@YAPAUlua_State@@H@Z) Output/LUA_Test00[d].exe : fatal error LNK1120: 2 unresolved externals Error executing link.exe. LUA_Test00[d].exe - 3 error(s), 0 warning(s) If anyone has experience with initial setup of LUA, I'd much appreciate a quick pointer in the right direction. Google is a little cryptic with this sort of thing... Thanks! MatrixCubedhttp://MatrixCubed.cjb.net [edited by - MatrixCubed on October 24, 2002 2:59:09 AM]

Thank you sQuid,

My problem is that I am building a DLL in which I embed Lua. My switches are set to MDd and MD (debug and release) and these switches seem to be the only one we can use for a DLL. If I try to use another switch, the compiler says:

fatal error C1189: #error : Please use the /MD switch for _AFXDLL builds

Does this mean I have to rebuild the Lua files with these same switches? Would that work?

Exactly.

In general, tho, if you''re going to make a library that extends the Lua static library, you may as well add the files into your project. That''ll ensure that the build options are in sync; and it''ll allow you to easily make any minute changes to the Lua source that you need to.

Don''t listen to me. I''ve had too much coffee.

Whaaaaaa!!! It is working without any strange error message now!! I just added the source files to my project (I would never had thought about that... do I need some sleep?
