Question

在构建项目时，我得到了一些未定义的引用。这是构建日志：

这是我的链接命令：

g++ -mwindows -l glew32 -l glew32s -l glu32 -l opengl32 -o test.exe src\window.o src\test.o src\main.o

这是对的吗？我正在使用64位的glew二进制文件（我认为32s并不意味着什么）。他们只是想与视觉工作室一起使用吗？

这是我的代码中包含的内容：

#include "Windows.h"
#include "GL/glew.h"
#include "GL/wglew.h"
#include "GL/gl.h"
#include "GL/glu.h"
#include "test.h"

我正在使用Eclipse Indigo CDT，MinGW，Win32，OpenGL和glew。

Answer 1

我解决了“glew undefined reference”问题。

我的开发环境是在Windows 7（x64）上使用MinGW进行CDT的日食。

解决方案有以下3个步骤：

添加源代码：#define GLEW_STATIC
添加链接器标记：-lglew32s -lopengl32 -lfreeglut
添加编译标记：gcc -DGLEW_STATIC

如果需要，您必须添加-lglu32 -glut32等

OpenGL + GLEW + MinGW应用程序链接问题
