• windows 需安装 MinGW, install gcc、g++、gdb 和 mingw32-make 并 进入到 MinGW\bin 文件夹下 把 mingw32-make.exe 修改成 make.exe

  MinGW 不要下载 MinGW-w64因为后面可能会出现问题 MinGW，即 Minimalist GNU For Windows。它是一些头文件和端口库的集合，该集合允许人们在没有第三方动态链接库的情况下使用 GCC 产生 Win32 程序。

• vscode 插件 C/C++、C/C++ Project Generator

• glfw 下载 Windows pre-compiled binaries

  选择Windows pre-compiled binaries，因为我们使用的 MinGW 所以选择 32-bit Windows binaries 对于 Ubuntu，通过 sudo apt install libglfw3-dev libglfw3 安装 glfw

• glad 在线服务 生成静态库

  > gcc ./src/glad.c -c -I ./include/ // 生成 .o文件
  > ar -rc libglad.a glad.o           // 生成我们所需要的 .a文件

  将生成的 libglad.a 复制到 lib 文件下

• glm 复制到 include 目录下

• imgui 复制到 include 目下,Makefile 中添加以下命令

  # define the C source files
  SOURCES     := $(wildcard $(patsubst %,%/*.cpp, $(SOURCEDIRS)))
  SOURCES += include/imgui/imgui_impl_glfw.cpp include/imgui/imgui_impl_opengl3.cpp
  SOURCES += include/imgui/imgui.cpp include/imgui/imgui_demo.cpp include/imgui/imgui_draw.cpp include/imgui/imgui_widgets.cpp

• assimp 下载已编译好的文件 Assimp3-1-1_MinGW4-8-1_Win32.zip

  对于 Ubuntu，通过 sudo apt install libassimp-dev 安装 assimp

• 参考 Makefile 文件

示例

1. Run 和 Clean

测试代码

#include <glad/glad.h>
#include <GLFW/glfw3.h>

#include <iostream>

void framebuffer_size_callback(GLFWwindow *window, int width, int height);
void processInput(GLFWwindow *window);

const unsigned int SCR_WIDTH = 800;
const unsigned int SCR_HEIGHT = 600;

int main()
{
    glfwInit();
    glfwWindowHint(GLFW_CONTEXT_VERSION_MAJOR, 3);
    glfwWindowHint(GLFW_CONTEXT_VERSION_MINOR, 3);
    glfwWindowHint(GLFW_OPENGL_PROFILE, GLFW_OPENGL_CORE_PROFILE);

    GLFWwindow *window = glfwCreateWindow(SCR_WIDTH, SCR_HEIGHT, "LearnOpenGL", NULL, NULL);
    if (window == NULL)
    {
        std::cout << "Failed to create GLFW window" << std::endl;
        glfwTerminate();
        return -1;
    }
    glfwMakeContextCurrent(window);
    glfwSetFramebufferSizeCallback(window, framebuffer_size_callback);

    if (!gladLoadGLLoader((GLADloadproc)glfwGetProcAddress))
    {
        std::cout << "Failed to initialize GLAD" << std::endl;
        return -1;
    }

    while (!glfwWindowShouldClose(window))
    {
        processInput(window);
        glfwSwapBuffers(window);
        glfwPollEvents();
    }

    glfwTerminate();
    return 0;
}

void processInput(GLFWwindow *window)
{
    if (glfwGetKey(window, GLFW_KEY_ESCAPE) == GLFW_PRESS)
        glfwSetWindowShouldClose(window, true);
}

void framebuffer_size_callback(GLFWwindow *window, int width, int height)
{
    glViewport(0, 0, width, height);
}

执行命令 run 编译和运行.exe 程序

make run dir=01_test_glfw

执行命令 clean 删除 .exe 和对应文件夹下的.o 文件

make clean dir=01_test_glfw

2. Debug

需要设置调试一个文件 修改 tasks.json下面的条目

 "label": "build",
  "type": "shell",
  "group": {
      "kind": "build",
      "isDefault": true
  },
  "windows": {
      "command": "powershell",
      "args": [
          "-c",
          "make dir=01_test_glfw", // 调式 01_test_glfw/main.cpp
      ]
  },
