Mac下编译x264 for Android

前言

在编译之前建议先去了解交叉编辑环境生成教程，后续编译基于此。
自定义NDK交叉编译链(toolchain)

环境

操作系统：mac os 10.14.2
ndk版本：android-ndk-r20
libx264: x264-snapshot-20191211-2245

脚本

• 下载x264
• 进入下载后的x264目录，创建build_android.sh

#!/bin/sh
NDK_HOME=~/Library/Android/sdk/ndk-bundle
#自定义NDK toolchain目录
CHAIN_ENV=${NDK_HOME}/Chain/android-toolchain

#ARCH=arm64
ANDROID_ARCH=arm

# All the built binaries, libs and their header will be installed here
PREFIX=~
# static or share libs dir
OUT_PUT=${PREFIX}/android-output

# The cross-compile toolchain we use
TOOLCHAIN=${ANDROID_ARCH}-linux-androideabi

# The path of standalone NDK toolchain
# Refer to https://developer.android.com/ndk/guides/standalone_toolchain.html
NDK_TOOLCHAIN=${CHAIN_ENV}/${ANDROID_ARCH}

# Set Android Sysroot according to API and arch
SYSROOT=${NDK_TOOLCHAIN}/sysroot

ARM_LIB=$SYSROOT/usr/lib

# Binutils path
CROSS_PREFIX=${NDK_TOOLCHAIN}/bin/${TOOLCHAIN}


./configure \
    --prefix=${OUT_PUT}/libx264/${ANDROID_ARCH} \
    --cross-prefix=${CROSS_PREFIX}- \
    --sysroot=$SYSROOT \
    --enable-static \
    --enable-pic \
    --disable-asm \
    --host=arm-linux \

make clean
make install

• 添加执行权相执行脚本
