c++ - 对 'imp____glewEnableVertexAttribArray' 的 undefined reference

Question

我正在尝试根据用 C++ 编写并打开 gl 2.1 的教程编译我正在做的程序。但是，我不喜欢 FreeGLUT，所以我决定将窗口程序更改为 SFML。然而，我的问题是当我尝试构建程序时出现这些错误:

我在程序中包含了以下库:

#include <GL/glew.h>
#include <SFML/System.hpp>
#include <SFML/Window.hpp>
#include <iostream>
#include <stdio.h>
#include <stdlib.h>

我还链接了这些:

-lsfml-system
-lsfml-window
-lopengl32
-lglu32
-lglew32

Answer 1

*_imp__* 类型的 undefined reference (名称修改)是由于尝试链接由/为 Visual Studio/MSVC 编译的库而引起的。

解决方案是下载二进制文件或针对您的特定平台进行编译(这通常与 mingw32 相关)。
