第〇步：
下载glfw：http://www.glfw.org/download.html，下载解压好，暂且成目录名字为 glfw3-3.x.x
ubuntu下安装：sudo apt-get install libglew-dev glew-utils
第一步：编译glfw：
(1): 安装依赖库，sudo apt-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build子目录， 命令行执行 cmake-gui， 源码目录选择glfw3-3.x.x, 目标目录选择build。 configure，generate
(3): 命令行模式，cd build，执行 make， sudo make install .
第二步：使用glfw（关键）
建立main.cpp, 敲入下面源码：
#include <iostream> #include <GL/glew.h> #include <GLFW/glfw3.h> using namespace std; void key_callback(GLFWwindow* window, int key, int scancode, int action, int mode); const GLuint WIDTH = 800, HEIGHT = 600; int main() { cout << "Starting GLFW context, OpenGL3.3" << endl; glfwInit(); glfwWindowHint(GLFW_CONTEXT_VERSION_MAJOR, 3); glfwWindowHint(GLFW_CONTEXT_VERSION_MINOR, 3); glfwWindowHint(GLFW_OPENGL_PROFILE, GLFW_OPENGL_CORE_PROFILE); glfwWindowHint(GLFW_RESIZABLE, GL_FALSE); GLFWwindow* window = glfwCreateWindow(WIDTH, HEIGHT, "LearnOpenGL", NULL, NULL); if(window == NULL) { std::cout << "Failed to create GLFW window" << std::endl; glfwTerminate(); return -1; } glViewport(0, 0, WIDTH, HEIGHT); while(!glfwWindowShouldClose(window)) { glfwPollEvents(); glClearColor(0.2f, 0.3f, 0.3f, 1.0f); glClear(GL_COLOR_BUFFER_BIT); glfwSwapBuffers(window); } glfwTerminate(); return 0; } void key_callback(GLFWwindow* window, int key, int scancode, int action, int mode) { std::cout << key << std::endl; if (key == GLFW_KEY_ESCAPE && action == GLFW_PRESS) glfwSetWindowShouldClose(window, GL_TRUE); }
编译： g++ -c main.cpp g++ mian.o -o main.exec -lGL - lGLU -lglfw3 -lX11 -lXxf86vm -lXrandr -lpthread -lXi -lXcursor -lXinerama
编译也可用CmakeLists.txt:
project(OpenGL_1) cmake_minimum_required(VERSION 2.8) aux_source_directory(. SRC_LIST) LINK_LIBRARIES(glfw3) LINK_LIBRARIES(X11) LINK_LIBRARIES(Xxf86vm) LINK_LIBRARIES(Xrandr) LINK_LIBRARIES(pthread) LINK_LIBRARIES(Xi) LINK_LIBRARIES(Xcursor) LINK_LIBRARIES(Xinerama) LINK_LIBRARIES(GL) LINK_LIBRARIES(GLU) add_executable(${PROJECT_NAME} ${SRC_LIST})
