[Libav-user] build FFMPEG ubuntu 16

[retep peter]

I need a advice :) I have tried compile ffmpeg 2.8.15 from source under
Ubuntu 16 LTS. I need compile it for one SDK, I can't use ffmpeg from
repository. I compiled ffmpeg successfully. But I have got issues with my
specify SDK, when I try compile my code with SDK:

SDK.so: undefined reference to `av_rescale_q at LIBAVUTIL_FFMPEG_54'

I suppose that issues are in symbols name. I tried read symbols with

readelf -s libavutil-ffmpeg.so.54

I get in my compiled ffmpeg something like this

   158: 0000000000024170    55 FUNC    GLOBAL DEFAULT   12
av_rescale_q@@LIBAVUTIL_54

I tried this with libavutil-ffmpeg.so.54 from repository and i get

   158: 0000000000024170    55 FUNC    GLOBAL DEFAULT   12
av_rescale_q@@LIBAVUTIL_FFMPEG_54

I suppose that I need add a suffix "FFMPEG" to symbols name. I use this
configuration for build ffmpeg, it same as configuration of build from
repository :

sudo ./configure --prefix=/usr --extra-version=0ubuntu0.16.04.1
--build-suffix=-ffmpeg --toolchain=hardened
--libdir=/usr/lib/x86_64-linux-gnu
--incdir=/usr/include/x86_64-linux-gnu --cc=cc --cxx=g++ --enable-gpl

--enable-libdc1394 --enable-libiec61883 --enable-libzmq
--enable-frei0r --enable-libx264 --enable-libopencv

Could you help me how add suffix "-ffmpeg" to symbols name? Thanks

Best Regard
