android 编译ffmpeg+x264出现找不到libx264文件

yishengzhile

1.在ubuntu下进行的编译
2.使用的是ndk-r6版本
3.首先用ndk编译生成了libx264.a静态库
4.编译ffmpeg
shell如下：

#!/bin/bash

PKG_CONFIG_PATH="/home/sfj/ffmpeg-x264/ffmpeg-0.8.1/jni/lib/pkgconfig"  

exportPKG_CONFIG_PATH

PREBUILT=/home/sfj/ndk6/android-ndk-r6/toolchains/arm-linux-androideabi-4.4.3/prebuilt/linux-x86

PLATFORM=/home/sfj/ndk6/android-ndk-r6/platforms/android-9/arch-arm

./configure  \

--cc=$PREBUILT/bin/arm-linux-androideabi-gcc\

--cross-prefix=$PREBUILT/bin/arm-linux-androideabi-\

--extra-cflags="-I/home/sfj/ffmpeg-x264/ffmpeg-0.8.1/jni/include  -fPIC -DANDROID" \

--extra-ldflags="-L/home/sfj/ffmpeg-x264/ffmpeg-0.8.1/jni/lib -Wl,-T,$PREBUILT/arm-linux-androideabi/lib/ldscripts/armelf_linux_eabi.x-Wl,-rpath-link=$PLATFORM/usr/lib -L$PLATFORM/usr/lib -nostdlib$PREBUILT/lib/gcc/arm-linux-androideabi/4.4.3/crtbegin.o$PREBUILT/lib/gcc/arm-linux-androideabi/4.4.3/crtend.o -lc -lm -ldl" \

--bindir="/home/sfj/ffmpeg-x264/ffmpeg-0.8.1/jni/bin"\

--extra-libs="-ldl"\

--target-os=linux\

--arch=arm \

--enable-version3\

--enable-gpl \

--enable-nonfree\

--disable-stripping\

--disable-ffmpeg\

--disable-ffplay\

--disable-ffserver\

--disable-ffprobe\

--enable-muxers\

--disable-devices\

--disable-protocols\

--enable-protocol=file\

--enable-libx264\

--enable-encoder=libx264\

--enable-decoder=h264\

--enable-avfilter\

--enable-network\

--enable-avdevice\

--disable-asm \

--enable-cross-compile\

--strip=$PREBUILT/bin/arm-linux-androideabi-strip\

shell结束

5.运行config.sh的时候，log如下：

希望大牛给指点一下

链接找不到libx264.a或者libx264.so，请确认你的指定目录下有着个库：
/home/sfj/ffmpeg-x264/ffmpeg-0.8.1/jni/lib
