**This is another more radical fork of ```cocos2d-x v4```, use OpenAL for all platforms, single texture multi GPU texture handler, C++14/17, etc.**

2020-08-20 09:11:08 +08:00
6. Remark: If you use non-sdk provided CMake edition, you need download ```ninja``` from https://github.com/ninja-build/ninja/releases, and copy ```ninja.exe``` to cmake's bin directory
2020-02-07 17:17:50 +08:00
2020-08-04 11:23:36 +08:00
#### iOS
2020-08-27 12:59:48 +08:00
1. Ensure xcode11+ & [cmake3.6+ ](https://github.com/Kitware/CMake/releases ) installed, install cmake command line support: ```sudo "/Applications/CMake.app/Contents/bin/cmake-gui" --install```
2020-08-27 12:51:35 +08:00
2. Execute follow command
2020-02-12 16:58:47 +08:00
```sudo xcode-select -switch /Applications/Xcode.app/Contents/Developer```
2020-08-27 12:51:35 +08:00
3. Generate xcode project
2020-02-12 16:58:47 +08:00
```sh
2020-08-24 16:26:12 +08:00
# for device arm64
cmake -S . -B build -GXcode -DCMAKE_TOOLCHAIN_FILE=cmake/ios.mini.cmake
# for device combined armv7,arm64
2020-08-24 16:28:55 +08:00
# cmake -S . -B build -GXcode -DCMAKE_TOOLCHAIN_FILE=cmake/ios.mini.cmake "-DCMAKE_OSX_ARCHITECTURES=armv7;arm64"
2020-08-24 16:26:12 +08:00
# for simulator x86_64
# cmake -S . -B build -GXcode -DCMAKE_TOOLCHAIN_FILE=cmake/ios.mini.cmake -DCMAKE_OSX_SYSROOT=iphonesimulator
2020-02-12 16:58:47 +08:00
```
2020-08-27 12:51:35 +08:00
4. After cmake generate finish, you can open xcode project at ```build``` folder and run cpp-tests or other test targets.

2020-08-27 12:51:35 +08:00
5. Notes
2020-08-24 16:30:47 +08:00
a. **The code sign required to run ios app on device, just change bundle identifier until the auto manage siging solved**
2020-08-24 16:26:12 +08:00
b. **EGNX only provide armv7,arm64,x86_64 prebuilt libraries for ios**
2020-06-19 18:26:24 +08:00
2020-08-04 11:23:36 +08:00
### Pitfalls
* ThreadLocalStorage(TLS)
- ios x86 simulator ios>=10
- ios x64 or devices(armv7,arm64) ios sdk>=9.0
- the openal-soft maintained by kcat use TLS
