ubuntu14.04 上使用glfw

第零步:下载glfw: 百度, 下载解压好,暂且成目录名字为 glfw3-3.x.x

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 

#include 
#include 

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})
