- [x] 29. Fix OpenGL error 0x501 when use compressd texture on device, caused by backend TextureGL: initWithZeros
2019-11-25 10:22:58 +08:00
- [ ] XX1. Cache ProgramState or use object_pool
- [ ] XX2. Remove socket.io websockets, use yasio for socket connection solution
- [ ] XX3. Fully streaming play for all media file: .mp4, .mp3, .ogg, .wav
- [ ] XX4. Streaming load for .ttf with freetype2
- [x] XX5. Remove CCB(already removed in v4)
- [ ] XX6. Sync 3rd bin
- [ ] XX7. Purely offthread load texture, use shared gl context
2019-11-25 14:39:46 +08:00
- [ ] XX8. Use git submodule to manage 3rd libs.
2019-11-25 10:22:58 +08:00
- [ ] Upgrade 3rd stubs to latest stable edition for all platforms
- [ ] zlib to 1.2.11

### 快速开始
#### windows
安装CMake， < br >
根据安装的 Visual Studio 版本，执行下面的命令，解决方案就生成在 build 目录下了。< br >
打开cpp-tests.sln， < br >
```
2020-02-23 23:00:14 +08:00
cd engine-x\tests\cpp-tests
2020-02-07 17:17:50 +08:00
cmake -S .\ -B .\build -G “Visual Studio 14 2015 Win32”
or
cmake -S .\ -B .\build -G “Visual Studio 16 2019” -A Win32
```
#### android
安装 Android Studio (推荐3.5.3)，打开 SDKManager， < br >
2020-02-23 23:00:14 +08:00
打开project， < br >
2020-02-07 17:17:50 +08:00
等待Gradle sync完成后， ， < br >
```
LLDB 推荐3.1
CMake 推荐 3.10.2
NDK 推荐 20.1
```

如果报缺少Ninja, 从https://github.com/ninja-build/ninja/releases下载，
2020-02-07 17:17:50 +08:00
2020-02-12 16:58:47 +08:00
#### ios
确保最新版xcode已安装
安装brew: ```/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"```
brew安装完成后，
```sh
brew update
brew install git
brew install cmake
brew install autoconf
brew install automake
brew install libtool
```
执行如下命令确保cmake能成功生成xcode工程:
```sudo xcode-select -switch /Applications/Xcode.app/Contents/Developer```
2020-02-23 23:00:14 +08:00
生成xcode工程, 进入engine-x根目录执行如下命令:
2020-02-12 16:58:47 +08:00
```sh
mkdir build
cd build
cmake .. -GXcode -DCMAKE_SYSTEM_NAME=iOS -DCMAKE_OSX_SYSROOT=iphonesimulator
2020-07-21 23:06:01 +08:00
# for simulator64
# cmake .. -G Xcode -DCMAKE_TOOLCHAIN_FILE=../cmake/ios.toolchain.cmake -DPLATFORM=SIMULATOR64 -DENABLE_ARC=0 -DENABLE_BITCODE=0
# for (armv7, armv7s, arm64)
# cmake .. -G Xcode -DCMAKE_TOOLCHAIN_FILE=../cmake/ios.toolchain.cmake -DPLATFORM=OS -DENABLE_ARC=0 -DENABLE_BITCODE=0
# for device 64
# cmake .. -G Xcode -DCMAKE_TOOLCHAIN_FILE=../cmake/ios.toolchain.cmake -DPLATFORM=OS64 -DENABLE_ARC=0 -DENABLE_BITCODE=0
2020-02-12 16:58:47 +08:00
```
之后就可以用xcode打开, 选择cpp-tests编译运行，
