Ubuntu下glfw的安装与使用

编译D435出错

CMake Error: The following variables are used in this project,but they are set to NOTFOUND.

第一步，下载glfw

到地址www.glfw.org下载glfw source code：glfw-3.2.1.zip，解压

$unzip glfw-3.2.1.zip -d glfw-3.2.1

第二步，编译安装glfw

1. 安装依赖库，

$sudoapt-get build-dep glfw

$sudo apt-get install cmake xorg-dev libglu1-mesa-dev

2.进入 glfw3-3.x.x 目录，建立glfw-build子目录，

$sudo mkdir glfw-build

3. 进入glfw-build，使用cmake命令生成Makefile

$sudo cmake ../

4. make && make install

$sudo make

$sudo make install

第三步，使用glfw

建立main.cpp 输入下面的代码：

[plain] view plain copy

1. #include
3. intmain(void)
4. {
5. GLFWwindow*window;
7. /*Initializethelibrary*/
8. if(!glfwInit())
9. return-1;
11. /*CreateawindowedmodewindowanditsOpenGLcontext*/
12. window=glfwCreateWindow(640,480,"HelloWorld",NULL,NULL);
13. if(!window)
14. {
15. glfwTerminate();
16. return-1;
17. }
19. /*Makethewindow'scontextcurrent*/
20. glfwMakeContextCurrent(window);
22. /*Loopuntiltheuserclosesthewindow*/
23. while(!glfwWindowShouldClose(window))
24. {
25. /*Renderhere*/
27. /*Swapfrontandbackbuffers*/
28. glfwSwapBuffers(window);
30. /*Pollforandprocessevents*/
31. glfwPollEvents();
32. }
34. glfwTerminate();
35. return0;
36. }
