## Windows 下编译
### `helloengine_win`
```shell
# 0
pwd
# X:\xx\xx\GameEngineFromScratch

# 1
cd Platform/Windows/
mkdir -p build\helloengine_win
cd build\helloengine_win

# 2
clang -l user32.lib -l gdi32.lib -o helloengine_win.exe ../../helloengine_win.c

# 3 运行
helloengine_win.exe
```

### `helloengine_d2d`

```shell
# 0
pwd
# X:\xx\xx\GameEngineFromScratch

# 1
cd Platform/Windows/
mkdir -p build\helloengine_d2d
cd build\helloengine_d2d

# 2
clang -l user32.lib -l ole32.lib -l d2d1.lib -o helloengine_d2d.exe ../../helloengine_d2d.cpp

# 3 运行
helloengine_d2d.exe
```

### `helloengine_d3d`

安装 DirectXMath
```shell
git submodule add https://github.com/Microsoft/DirectXMath.git DirectXMath
git submodule init DirectXMath
git submodule update DirectXMath
```

```shell
# 0
pwd
# X:\xx\xx\GameEngineFromScratch

# 1
cd Platform/Windows/
mkdir -p build\helloengine_d3d
cd build\helloengine_d3d

# 2 编译Shader（D3D规格）
# 使用 `Developer Command Prompt`
fxc /T vs_5_0 /Zi /Fo copy.vso ../../copy.vs
fxc /T ps_5_0 /Zi /Fo copy.pso ../../copy.ps

# 3  debug
# clang-cl -I ../../DirectXMath/Inc/ -c -Z7 -o helloengine_d3d.obj ../../helloengine_d3d.cpp
# link -debug user32.lib d3d11.lib d3dcompiler.lib helloengine_d3d.obj

# 4 release
clang -I  ../../DirectXMath/Inc -l user32.lib -l d3d11.lib -l d3dcompiler.lib -o helloengine_d3d.exe ../../helloengine_d3d.cpp

# 5 运行
helloengine_d3d.exe
```

### `helloengine_opengl`

```shell
# 0
pwd
# X:\xx\xx\GameEngineFromScratch

# 1
cd Platform/Windows/
mkdir build\helloengine_opengl
cd build\helloengine_opengl

# 2
clang-cl /EHsc -o helloengine_opengl ../../helloengine_opengl.cpp user32.lib gdi32.lib opengl32.lib
# 或
clang -o helloengine_opengl.exe ../../helloengine_opengl.cpp -luser32 -lgdi32 -lopengl3

# 3
helloengine_opengl.exe
```

## Mac 下 编译
```shell
# 0
pwd
# X:\xx\xx\GameEngineFromScratch

# 1
cd Platform/Darwin/
mkdir  build

cmake -H. -Bbuild -GXcode -DCMAKE_EXPORT_COMPILE_COMMANDS=1
cmake --build build/
open build/test_mac_app.xcodeproj

# 使用 Xcode 编译运行
```
## 第5章

1. 编译命令

   ```bash
   # 在项目的根目录
   mkdir build
   cd build
   cmake ..
   make 

   # 执行
   ./Empty/Empty
   ```

## 第7章

   ```shell
    clang -l user32.lib -o helloengine_win.exe helloengine_win.c
   ```

2. cl 编译命令

   ```shell
   cl -l user32.lib helloengine_win.c
   ```

3. gcc 编译 helloengine_xcb

   ```shell
   gcc -Wall helloengine_xcb.c -lxcb -o helloengine_xcb

   # 运行
   ./helloengine_xcb
   ```

4. gcc 编译 helloengine_opengl

   ```shell
