VS2019/openGL/freeglut配置
作者:互联网
freeglut是opengl跨平台实用工具库,用于做窗口界面,封装各个平台鼠标键盘事件等等。用于替代早期的glut库(1998年后就不在更新维护)。
【我这里使用的是编译好的包,可以直接跳到第3步,配置。】
安装及使用
环境:win10 VS2019
1. 下载freeglut:https://sourceforge.net/projects/freeglut/
2. cmake打开生成VS工程:
a. build目录:为VS工程生成目录。
b. FREEGLUT_BUILD_SHARED_LIBS、FREEGLUT_BUILD_STATIC_LIBS:分别为共享动态库项目和静态库项目这里都选择。
c. 点击Configure(配置),再点击Generate(生成)。
生成freeglut工程后,选择freeglut项目进行编译得到freeglutd.lib、freeglutd.dll 库文件
3. opengl项目配置:
a. 项目属性 ----> C/C++ —> 附加包含目录 —> D:\Soft\freeglut-3.0.0\include
b. 项目属性 ----> 链接器 —> 常规 —> 附加库目录 —> D:\Soft\freeglut-3.0.0\Build-x64\lib
c. 项目属性 ----> 链接器 —> 输入 —> 附加依赖项 —>
opencv_world3411d.lib
opencv_world3411.lib
#上面两个是opencv的#下面这行我加了绝对路径,不然找不到freeglutd.lib
#至于上面opencv的附加依赖项没有绝对路径,应该是opencv配置了环境变量
#而freeglutd没有添加环境变量
D:\Soft\freeglut-3.0.0\Build-x64\lib\Debug\freeglutd.lib
d. freeglutd.dll 库文件放到运行程序exe目录下
