OS X下 Android NDK 编译 libuv

准备工作

1、安装 NDK 下载对应版本，并添加安装路径至环境变量 (我用的是NDK14 rb，貌似最新的NDK编译有问题)

2、下载libuv 源码，并解压，我下载的版本是v1.11.0 这里提一句，貌似v1.12.0版本生成的Makefile貌似有一行有误，需要修改下，才能编译成功

下载安装gyp

进入解压目录

git clone https://chromium.googlesource.com/external/gyp.git build/gyp
cd build/gyp
pip install setuptools
sudo python setup.py install

通常情况下就安装好了然后回到解压目录下，修改android-configure，很遗憾，README里面官方给出的方案并不能直接运行。编译arm架构的脚本如下

#!/bin/bash

export TOOLCHAIN=$PWD/android-toolchain
mkdir -p $TOOLCHAIN
$1/build/tools/make-standalone-toolchain.sh \
    --toolchain=arm-linux-androideabi-4.9 \
    --arch=arm \
    --install-dir=$TOOLCHAIN \
    --platform=android-14 \
    --force
export PATH=$TOOLCHAIN/bin:$PATH
export AR=arm-linux-androideabi-ar
export CC=arm-linux-androideabi-gcc
export CXX=arm-linux-androideabi-g++
export LINK=arm-linux-androideabi-g++
export PLATFORM=android

export ARCH_FLAGS="-mthumb"
export ARCH_LINK=
export CPPFLAGS=" ${ARCH_FLAGS} -fpic -ffunction-sections -funwind-tables -fstack-protector -fno-strict-aliasing -finline-limit=64 "
export CXXFLAGS=" ${ARCH_FLAGS} -fpic -ffunction-sections -funwind-tables -fstack-protector -fno-strict-aliasing -finline-limit=64 -frtti -fexceptions "
export CFLAGS=" ${ARCH_FLAGS} -fpic -ffunction-sections -funwind-tables -fstack-protector -fno-strict-aliasing -finline-limit=64 "
export LDFLAGS=" ${ARCH_LINK} "

if [[ $2 == 'gyp' ]]
  then
    ./gyp_uv.py -Dtarget_arch=arm -DOS=android -f make-android
fi

退出保存以后 运行

source ./android-configure $NDK gyp && make -C out

在out/Debug目录下就会有生成好的 libuv.a

生成arm64-v8a架构的静态库

#!/bin/bash

export TOOLCHAIN=$PWD/android-toolchain
mkdir -p $TOOLCHAIN
$1/build/tools/make-standalone-toolchain.sh \
    --toolchain=aarch64-linux-android-4.9 \
    --arch=arm64 \
    --install-dir=$TOOLCHAIN \
    --platform=android-21 \
    --force
export PATH=$TOOLCHAIN/bin:$PATH
export AR=aarch64-linux-android-ar
export CC=aarch64-linux-android-gcc
export CXX=aarch64-linux-android-g++
export LINK=aarch64-linux-android-g++
export PLATFORM=android


export ARCH_FLAGS=
export ARCH_LINK=
export CPPFLAGS=" ${ARCH_FLAGS} -fpic -ffunction-sections -funwind-tables -fstack-protector -fno-strict-aliasing -finline-limit=64 "
export CXXFLAGS=" ${ARCH_FLAGS} -fpic -ffunction-sections -funwind-tables -fstack-protector -fno-strict-aliasing -finline-limit=64 -frtti -fexceptions "
export CFLAGS=" ${ARCH_FLAGS} -fpic -ffunction-sections -funwind-tables -fstack-protector -fno-strict-aliasing -finline-limit=64 "
export LDFLAGS=" ${ARCH_LINK} "


if [[ $2 == 'gyp' ]]
  then
    ./gyp_uv.py -Dtarget_arch=arm64 -DOS=android -f make-android
fi

armv7a的

#!/bin/bash

export TOOLCHAIN=$PWD/android-toolchain
mkdir -p $TOOLCHAIN
$1/build/tools/make-standalone-toolchain.sh \
    --toolchain=arm-linux-androideabi-4.9 \
