VC开发lua嵌入脚本语言相关问题

编译问题

    #include <stdio.h>
    #include <lua.h>
    #include <lauxlib.h>
    #include <lualib.h>
   
    int main (void) {
      char buff[256];
      int error;
      lua_State *L = lua_open();   /* opens Lua */
      luaopen_base(L);             /* opens the basic library */
      luaopen_table(L);            /* opens the table library */
      luaopen_io(L);               /* opens the I/O library */
      luaopen_string(L);           /* opens the string lib. */
      luaopen_math(L);             /* opens the math lib. */
   
      while (fgets(buff, sizeof(buff), stdin) != NULL) {
        error = luaL_loadbuffer(L, buff, strlen(buff), "line") ||
                lua_pcall(L, 0, 0, 0);
        if (error) {
          fprintf(stderr, "%s", lua_tostring(L, -1));
          lua_pop(L, 1);  /* pop error message from the stack */
        }
      }
   
      lua_close(L);
      return 0;
    }
这段程序在编译时会报链接错误。

需要在lua的头文件中作以下修改： 

   #ifdef __cplusplus
    extern "C" {
    #endif
       ...
    #ifdef __cplusplus
    }
    #endif
