### Quick Start

#### Common Requirement [Python](https://www.python.org/downloads/)
  * Python-2.7.17+, Python-3.7+ 

#### Prerequisites
  1. Enter ```axmol``` root directory
  2. Run ```python setup.py```, restart the console after it has finished for environment variables to take effect

#### Windows (64/32 bit  Visual Studio 2019/2022)
  1. Install [CMake](https://cmake.org/)  3.22.1+  
  2. Install Visual Studio 2019/2022 (it's recommended that you only use these versions)  
  3. Execute the following commands in a command line (Console, Window Terminal or Powershell)
  
       ```cd axmol ```
  
     a) C++ 20:
     - for 32 bit Visual Studio 2019:
     ```cmake -S . -B build -G "Visual Studio 16 2019" -A Win32```
     - for 64 bit Visual Studio 2019:
     ```cmake -S . -B build -G "Visual Studio 16 2019" -A x64```
     - for 32 bit Visual Studio 2022:
     ```cmake -S . -B build -G "Visual Studio 17 2022" -A Win32```
     - for 64 bit Visual Studio 2022:
     ```cmake -S . -B build -G "Visual Studio 17 2022" -A x64```
     
     b) C++17
     - add ```-DCXX_STD=17``` for C++17 on your command line like:    
       cmake -S . -B build ```-DCXX_STD=17``` -G "Visual Studio 17 2022" -A x64
  
  4. Build excecutable in a command line (e.g. cpp-tests):  
    ```msbuild .\build\axmol.sln -target:cpp_tests -maxCpuCount```
    
#### Improve 'Visual Studio' workflow, support linking with engine prebuilt libs
See [windows workflow guide](https://github.com/axmolengine/axmol/issues/564)

#### Android

##### With Android Studio
  1. Install Android Studio 2021.1.1+
  2. When starting Android Studio for the first time, It will guide you to install the SDK and other tools, just install them
  3. Start Android and choose [Open an existing Android Studio Project] and select ```axmol\tests\cpp-tests\proj.android```
  4. Start Android Studio and Open [Tools][SDKManager], then switch to ```SDK Tools```, check the ```Show Package Details```, choose the following tools and click the button ```Apply``` to install them:  
     * Android SDK Platform 33  
     * Android Gradle Plugin (AGP) 7.2.2  
     * Android SDK Build-Tools 30.0.3 match with AGP, refer to: https://developer.android.com/studio/releases/gradle-plugin
     * Gradle 7.4.2  
     * NDK r23c+  
     * CMake 3.22.1+  
  5. Wait for ```Gradle sync``` finish.
  6. Note: If you use non-sdk provided CMake edition, you will need to download ```ninja``` from https://github.com/ninja-build/ninja/releases, and copy ```ninja.exe``` to cmake's bin directory
  
##### Without Android Studio
  1. Download command-tools from https://developer.android.com/studio#command-tools
  2. Install Android devtools (for example in windows)
  ```bat
  # unzip command-tools at D:\dev\adt\
  # Install android devtools
  cd D:\dev\adt\
  mkdir sdk
  .\cmdline-tools\bin\sdkmanager.bat --verbose --sdk_root=D:\dev\adt\sdk "platform-tools" "cmdline-tools;latest" "platforms;android-33" "build-tools;30.0.3" "cmake;3.22.1" "ndk;23.2.8568313"
  set ANDROID_HOME=D:\dev\adt\sdk
  
  # Goto xxx\proj.android
  .\gradlew.bat assembleRelease -PPROP_BUILD_TYPE=cmake -PPROP_APP_ABI=arm64-v8a --parallel --info
  ```

#### iOS, tvOS and macOS
  1. Ensure xcode12+ & [cmake3.21+](https://github.com/Kitware/CMake/releases) are installed, install cmake command line support: ```sudo "/Applications/CMake.app/Contents/bin/cmake-gui" --install```
  2. Execute the following command   
  ```sudo xcode-select -switch /Applications/Xcode.app/Contents/Developer```  
  3. Generate xcode project  
     - for ios arm64:  
     ```cmake -S . -B build -GXcode -DCMAKE_TOOLCHAIN_FILE=$AX_ROOT/cmake/ios.toolchain.cmake -DPLATFORM=OS64```
     - for ios armv7,arm64 combined:  
     ```cmake -S . -B build -GXcode -DCMAKE_TOOLCHAIN_FILE=$AX_ROOT/cmake/ios.toolchain.cmake -DPLATFORM=OS```
     - for ios simulator x86_64:  
     ```cmake -S . -B build -GXcode -DCMAKE_TOOLCHAIN_FILE=$AX_ROOT/cmake/ios.toolchain.cmake -DPLATFORM=SIMULATOR64```
     - for tvos arm64:  
     ```cmake -S . -B build -GXcode -DCMAKE_TOOLCHAIN_FILE=$AX_ROOT/cmake/ios.toolchain.cmake -DPLATFORM=TVOS```
     - for tvos simulator x86_64:  
     ```cmake -S . -B build -GXcode -DCMAKE_TOOLCHAIN_FILE=$AX_ROOT/cmake/ios.toolchain.cmake -DPLATFORM=SIMULATOR_TVOS```
     - for macos x86_64(Intel)
     ```cmake -S . -B build -GXcode -DCMAKE_OSX_ARCHITECTURES=x86_64```
     - for macos arm64(M1)
     ```cmake -S . -B build -GXcode -DCMAKE_OSX_ARCHITECTURES=arm64```

  4. After cmake finishes generating, you can open the xcode project at ```build``` folder and run cpp-tests or other test targets.  
  5. Notes  
     - **The code signing is required to run the ios/tvos app on your device, just change the bundle identifier until the auto manage signing is solved**  
     - **axmol only provides armv7, arm64, x86_64 prebuilt libraries for ios/tvos**

### New Project
- Cpp: `axmol new -p org.axmol.hellocpp -d D:\dev\projects\ -l cpp --portrait HelloCpp`
- Lua: `axmol new -p org.axmol.hellolua -d D:\dev\projects\ -l lua --portrait HelloLua`

### Notes
  * ThreadLocalStorage (TLS) 
    - ios x86 simulator ios>=10 and axmol no longer provide x86 libraries
    - ios x64 or devices (armv7, arm64) ios sdk>=9.0
    - the 'OpenAL Soft' maintained by kcat uses TLS
