我在 C++ 链接、静态与动态、.lib 与 .a 等方面不是很有经验。
请注意，下面我对所有 DevIL 库（DevIL、ILU、ILUT）都有 -l。至于库文件，我将 dll 放在 System32 和 SysWOW64 中，并将 .libs 放在 MinGW\lib 中。Eclipse 项目的“当前工具链”确实是 MinGW GCC。该项目只有 1 个源文件 facecube.cpp（有 main()）。我错过了什么？
包括：
#include "Angel.h"
#include <IL\config.h>
#include <IL\ilut_config.h>
#include <IL\il.h>
#include <IL\ilu.h>
#include <IL\ilut.h>
#include <iostream>
using namespace std;
编译器输出：
