编译FFMPEG + X264 - 未定义的引用

Question

我一直试图在网上找到一个解决方案，几天没有运气。我使用Ubuntu，并试图编译FFMPEG最新的稳定版本（1.0.1）与X264支持。我确信我卸载任何现有的X264然后我下载了最新的X264源和以下配置编译它：

./configure --prefix=$PREFIX \
    --enable-shared \
    --enable-static \
    --disable-gpac \
    --extra-cflags=" -I$ARM_INC -fPIC -DANDROID -fpic -mthumb-interwork -ffunction-sections -funwind-tables -fno-short-enums -D__ARM_ARCH_5__ -D__ARM_ARCH_5T__ -D__ARM_ARCH_5E__ -D__ARM_ARCH_5TE__ -Wno-psabi -march=armv5te -msoft-float -mthumb -Os -fomit-frame-pointer -fno-strict-aliasing -finline-limit=64 -DANDROID -Wa,--noexecstack -MMD -MP " \
    --extra-ldflags=" -nostdlib -Bdynamic -Wl,--no-undefined -Wl,-z,noexecstack -Wl,-z,nocopyreloc -Wl,-soname,/usr/lib/libz.so -Wl,-rpath-link=$ARM_LIB,-dynamic-linker=/system/bin/linker -L$ARM_LIB -lc -lm -ldl -lgcc" \
    --cross-prefix=${ARM_PRE}- \
    --disable-asm \
    --host=arm-linux \

    make clean
    make install

一切顺利的话，我检查了安装的版本：

x264 -V
    x264 0.129.x
    built on Dec 27 2012, gcc: 4.6.1
    configuration: --bit-depth=8 --chroma-format=all
    x264 license: GPL version 2 or later

然后我尝试编译FFMPEG有以下选项：

./configure --target-os=linux \
    --enable-libx264 \
    --enable-gpl \
    --prefix=$PREFIX \
    --extra-cflags="-I/home/tishu/Workspaces/ffmpeg/ffmpeg/jni/ffmpeg-1.0.1/android/armv7-a/include -I/home/tishu/Workspaces/ffmpeg/ffmpeg/jni/x264 -O3 -fpic -DANDROID -DHAVE_SYS_UIO_H=1 -Dipv6mr_interface=ipv6mr_ifindex -fasm -Wno-psabi -fno-short-enums  -fno-strict-aliasing -finline-limit=300 $OPTIMIZE_CFLAGS " \
    --extra-ldflags="-Wl,-rpath-link=$PLATFORM/usr/lib -L/home/tishu/Workspaces/ffmpeg/ffmpeg/jni/ffmpeg-1.0.1/android/armv7-a/lib -L$PLATFORM/usr/lib -nostdlib -lc -lm -ldl -llog" \
    --enable-cross-compile \
    --extra-libs="-lgcc" \
    --arch=arm \
    --cc=$PREBUILT/bin/arm-linux-androideabi-gcc \
    --cross-prefix=$PREBUILT/bin/arm-linux-androideabi- \
    --nm=$PREBUILT/bin/arm-linux-androideabi-nm \
    --sysroot=$PLATFORM \

在配置和使清洁/ make install的工作做好了，但是当我尝试创建.so文件以下命令将失败：

/home/tishu/Apps/android-ndk-r8d/toolchains/arm-linux-androideabi-4.4.3/prebuilt/linux-x86/bin/arm-linux-androideabi-ld 
    -rpath-link=./android/armv7-a/usr/lib -L/home/tishu/Apps/android-ndk-r8d/platforms/android-14/arch-arm/usr/lib -soname libffmpeg.so -shared -nostdlib  -z,noexecstack -Bsymbolic \
    --whole-archive --no-undefined -o ./android/armv7-a/libffmpeg.so libavcodec/libavcodec.a libavformat/libavformat.a libavutil/libavutil.a libswscale/libswscale.a -lc -lm -lz -ldl -llog  \
    --warn-once \
    --dynamic-linker=/system/bin/linker /home/tishu/Apps/android-ndk-r8d/toolchains/arm-linux-androideabi-4.4.3/prebuilt/linux-x86/lib/gcc/arm-linux-androideabi/4.4.3/libgcc.a

这种失败，出现以下的输出：

libavcodec/libavcodec.a(libx264.o): In function `X264_frame':

它正在寻找（129）的X264版本是一个用--enable-共享安装并成功编译。显然，所有的时候，不包括LIB 64编译罚款。

问：我如何指定包括最后命令路径？我尝试添加的路径，$ PATH，并且还加入这个与没有运气的说法：-I /家庭/ tishu /工作区/的ffmpeg / ffmpeg的/ JNI / X264

谢谢

对于跟随者（甚至不是机器人，但类似消息）

/.../mingw-w64-i686/lib/gcc/.../i686-w64-mingw32/bin/ld:

出现此常数“下降”初期2017年见https://trac.ffmpeg.org/ticket/6966和https://trac.ffmpeg.org/ticket/6932

修复：更新的ffmpeg，或者downdate libx264 ...什么...

虽然这些天它应该什么样的支持libx264的旧版本，以及...
