windows 下 vscode 配置 OpenGL 开发环境
## 参考
- 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](https://sourceforge.net/projects/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++`](https://marketplace.visualstudio.com/items?itemName=ms-vscode.cpptools)、[`C/C++ Project Generator`](https://marketplace.visualstudio.com/items?itemName=danielpinto8zz6.c-cpp-project-generator)
- glfw 下载 [`Windows pre-compiled binaries`](https://www.glfw.org/download.html)
> 选择**Windows pre-compiled binaries**，因为我们使用的 MinGW 所以选择 [32-bit Windows binaries](https://github.com/glfw/glfw/releases/download/3.3.4/glfw-3.3.4.bin.WIN32.zip)
> 对于 Ubuntu，通过 `sudo apt install libglfw3-dev libglfw3` 安装 glfw
- glad [在线服务](https://glad.dav1d.de/) 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
```mk
# 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](https://www.mediafire.com/file/jjiv41rv8euy3dt/Assimp3-1-1_MinGW4-8-1_Win32.zip/file)
> 对于 Ubuntu，通过 `sudo apt install libassimp-dev` 安装 assimp
- [参考 Makefile 文件](https://github.com/yocover/start-learning-opengl/blob/main/Makefile)
## 示例
### 1. Run 和 Clean
**测试代码**
```c++
#include
#include
#include
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**
```Bash
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**
```Bash
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
```js
"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
]
},
```
