macOS Big Sur(11.6.7/Intel CPU)编译Android/iOS/macOS版本的RocksDB 6.29.5

从 RocksDB 7.0 开始，RocksDB 要求编译的 C++ 必须支持 C++ 17 ，（ Dropping some compiler support in 7.0#9388）但是目前的Android/iOS版本显然暂时还不能大范围的适配 C++ 17，因此我们目前只能使用 6.x 版本。

Android:

# Android NDK 22.1.7171670

$ brew install git

$ brew install cmake

$ brew install sed

$ git clone https://github.com/facebook/rocksdb.git

$ git checkout v6.29.5

# 修改代码，消除警告视为错误，否则会编译不通过
$ gsed -i "s/-Werror//g" CMakeLists.txt

# Android最低支持的版本是 Android 23 低于这个版本会出现API缺失导致编译失败

$ cmake . -DCMAKE_ANDROID_NDK=/Users/xxxx/Library/Android/sdk/ndk-bundle \

$ make

iOS/macOS ARM:

#Xcode Version 13.2.1 (13C100)

$ brew install git

$ brew install cmake

$ git clone https://github.com/facebook/rocksdb.git

$ git checkout v6.29.5

$ export PORTABLE=1

$ export TARGET_OS=IOS

$ export ROCKSDB_LITE=1

$ export IOS_CROSS_COMPILE=1

# int128兼容支持，默认支持，但是在iOS设备上是不支持的
$ export TEST_UINT128_COMPAT=1

$ export DISABLE_WARNING_AS_ERROR=1

$ export DEBUG_LEVEL=0 

$ export EXTRA_CXXFLAGS="-DNPERF_CONTEXT -DNIOSTATS_CONTEXT"

# iOS目前只能构建静态库，不能构建动态库
$ make V=1 VERBOSE=1 -j16 static_lib

macOS x86:

#Xcode Version 13.2.1 (13C100)

$ brew install git

$ brew install cmake

$ git clone https://github.com/facebook/rocksdb.git

$ git checkout v6.29.5

$ make V=1 VERBOSE=1 -j16 static_lib

# make V=1 VERBOSE=1 -j16 shared_lib 动态库
