OpenGL + GLEW + MinGW应用程序链接问题

问题描述

在构建项目时，我得到了一些未定义的引用.这是构建日志:

I'm getting some undefined references when building my project. Here's the build log:

**** Build of configuration Debug for project test ****

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

这是正确的吗?我正在使用glew的64位二进制文​​件(我认为32位二进制文​​件没有任何意义).他们只是打算与Visual Studio一起使用吗?

Is this correct? I'm using the 64-bit binaries of glew (I think the 32s don't mean anything). Were they only meant to be used with visual studio?

这是我的代码中的包含内容:

Here's the includes in my code:

#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.

I am using Eclipse Indigo CDT, MinGW, Win32, OpenGL, and glew.

推荐答案

我解决了切换未定义引用"问题.

I solved "glew undefined reference" problems.

我的开发环境是Windows 7(x64)上的带有MinGW的Eclipse CDT.

My development environment is eclipse CDT with MinGW on Windows 7 (x64).

解决方案包括以下3个步骤:

The solution is the following 3 steps:

1. 添加源代码:#define GLEW_STATIC
2. 添加链接器标志:-lglew32s -lopengl32 -lfreeglut
3. 添加编译标志:gcc -DGLEW_STATIC

1. Add source code: #define GLEW_STATIC
2. Add linker flag: -lglew32s -lopengl32 -lfreeglut
3. Add compiling flag: gcc -DGLEW_STATIC

如果需要，您必须添加-lglu32 -glut32等.

If needed, you have to add -lglu32 -glut32 etc.
