使用lua源编译C代码

Question

    int init_lua (char *filename,lua_State *L){
//int inter;
//lua_State *L = luaL_newstate();

luaL_openlibs(L);

if(luaL_loadfile(L, filename) ){
    error(L, "cannot run configuration file: %s",lua_tostring(L, -1)); 
    return 1;
    }
if (lua_pcall(L, 0, 0, 0)){
    error(L, "lua_pcall() failed");
    return 2;
    }

return 0;
}
uint8_t get_interface(unsigned int inteiro,lua_State *L){
int inter;

lua_getglobal(L,"ret_ind"); //função a ser chamada
lua_pushnumber(L,inteiro); //argumento

// do the call (1 arguments, 1 result)     
if (lua_pcall(L, 1, 1, 0))
    error(L, "error running function 'f': %s",lua_tostring(L, -1));

if (!lua_isnumber(L, -1))
    error(L, "function 'f' must return a number");

inter = lua_tonumber(L, -1);
lua_pop(L, 1);  // pop returned value /

return (uint8_t)inter;
}


int main(void)
{

lua_State *L = luaL_newstate();
printf("apos o load3\n");
if (init_lua("pp.lua",L))
    printf("erro ao tentar inicializar arquivo lua\n");
uint8_t resul;
resul = get_interface(190,L);
printf("Index of array: %d\n",(int)resul);

resul = get_interface(10000,L);
printf("Index of array: %d\n",(int)resul);


return 0;
}

上面的代码为pp.c

interfaces = {190,3141592,10000}

function ret_ind (ip)
    for i, inter in ipairs(interfaces) do
            if  inter == ip then
            return i
        end
    end

    return 0;
end

上面的代码为pp.lua

和编译命令gcc -o pp pp.c -I/usr/include/lua5.1/-llua5.1

我正在尝试包含 lua 的源代码，因此我不需要在计算机上安装 lua。从系统中删除 liblua5.1-0-dev 后，我将无法编译以下代码。

gcc -std=c99 -O2 -I./lua5.1/src/pp.c -o pp.o -llua5.1

通过系统上的库，我可以使用本地源代码，但可以使用 -llua5.1 中的全局 lua5.1。

编辑

将 lua 源代码转换为 shed object (.so) 后，我得到了一个执行程序:OBS:我会将我使用的 makefile 作为本文的评论

gcc -o pp pp.c -I./lua5.1/src/-L./lua5.1/src/-llua5.1执行我使用的程序(必须执行下面的2条命令，这样ld才能找到.so文件)

LD_LIBRARY_PATH=./lua5.1/src/导出LD_LIBRARY_PATH并运行 ./pp

Answer 1

答案可以在以下位置找到: Compiling Lua - create .so files?制作 liblua5.1.so 使用 make so

使用的make文件:

# makefile for building Lua
# see ../INSTALL for installation instructions
# see ../Makefile and luaconf.h for further customization
