libx264 for android编译（重点是看那个configure如何配置）

1.2 使用ndk编译x264
1.  下载源码并编译
$ cd /opt/android/ndk/android-ndk-r10e/resources
$ git clone http://git.videolan.org/git/x264.git
$ cd x264


修改configure文件
$ vim configure
将下面的这四句：
else
    echo "SOSUFFIX=so" >> config.mak
    echo "SONAME=libx264.so.$API" >> config.mak
    echo "SOFLAGS=-shared -Wl, -soname, \$(SONAME)$SOFLAGS" >> config.mak
中的这句：
    echo "SONAME=libx264.so.$API" >> config.mak
改成：
    echo "SONAME=libx264.so" >> config.mak
【保存并退出】


创建配置脚本
$ vim android_x264_configure.sh
#!/bin/bash 
NDK=/opt/android/ndk/android-ndk-r10e
SYSROOT=$NDK/platforms/android-9/arch-arm/
TOOLCHAIN=$NDK/toolchains/arm-linux-androideabi-4.8/prebuilt/linux-x86_64


function build_one 
{
./configure \
    --prefix=$PREFIX \
    --enable-shared \
    --enable-static \
    --disable-gpac \
    --disable-cli \
    --cross-prefix=$TOOLCHAIN/bin/arm-linux-androideabi- \
    --host=arm-linux \
    --sysroot=$SYSROOT \
    --extra-cflags="-Os -fpic $ADDI_CFLAGS" \
    --extra-ldflags="$ADDI_LDFLAGS" \
    $ADDITIONAL_CONFIGURE_FLAG
}
CPU=arm
PREFIX=$(pwd)/android/$CPU
ADDI_CFLAGS=""

build_one
【保存并退出】
