导读：在构建项目时,我得到了一些未定义的引用.这是构建日志： **** Build of configuration Debug for project test ******** Internal Builder is used for build ****g++ -O0 -g3 -Wall -c -fmessage-length=0 -o srcmain.o ..srcmain.cppg++ -O0 -g3 -Wall

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 srcwindow.o srctest.o srcmain.o

它是否正确？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).它们只是意味着与视觉工作室一起使用吗？

这是我的代码中的包含：

#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.

解决方法

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
>添加链接器标志：-lglew32s -lopengl32 -lfreeglut
>添加编译标志：gcc -DGLEW_STATIC

如果需要,你必须添加-lglu32 -glut32等.
