test.c的:如何建立C程序和Lua
#include "lua.h"
#include "lauxlib.h"
#include "lualib.h"
int main(){
lua_State *L = luaL_newState(); /* opens Lua */
luaL_openlibs(L); /* opens the standard libraries */
luaL_dofile(L,"test.lua"); /* runs Lua scrip */
lua_close(L);
return 0;
}
編譯:
gcc -o test test.c -I/usr/local/Cellar/lua/5.1.5/include
然後我得到的錯誤:
test.c:7:18: warning: implicit declaration of function 'luaL_newState' is
invalid in C99 [-Wimplicit-function-declaration]
lua_State *L = luaL_newState(); /* opens Lua */
^
test.c:7:14: warning: incompatible integer to pointer conversion initializing
'lua_State *' (aka 'struct lua_State *') with an expression of type 'int'
[-Wint-conversion]
lua_State *L = luaL_newState(); /* opens Lua */

我通過自制軟件安裝的Lua:
ls /usr/local/Cellar/lua/5.1.5/include
lauxlib.h lua.h lua.hpp luaconf.h lualib.h
任何人都知道如何解決這個錯誤?謝謝。
構建示例時,您需要添加導入庫或'lua * .so'共享對象。未定義的引用來自鏈接器不知道這些lua C函數在哪裏。我不確定這會在你的Linux設置上。也許試試'which lua51.so'或者查看你的bin目錄。在'test.c'之前移動你的'-I'參數,並且應該修復警告。 – greatwolf
