Link error on Debian (Raspberry Pi)

Hello,

I am trying to build the newest Tvheadend from source on Raspberry Pi. I think I have all the neccessary libraries, however I cannot link it together:

/tmp/tvheadend/build.linux/src/plumbing/transcoding.o: In function `create_video_filter':
/tmp/tvheadend-build/tvheadend/src/plumbing/transcoding.c:1115: undefined reference to `avfilter_graph_parse_ptr'
/tmp/tvheadend-build/tvheadend/src/plumbing/transcoding.c:1093: undefined reference to `av_int_list_length_for_size'

What am I doing wrong?

If you've built it previously, try removing libav_static or running make distclean first

I tried running it and it didn't help. Where is the libav_static directory located? I cannot find it in the root of the sources...

This is the list of ffmpeg related libraries on my system:

  libavcodec                               56.60.100
  libavutil                                54.31.100
  libavformat                              56.40.101
  libavfilter                              5.40.101
  libavresample                            2.1.0

Apologies - I leapt to a conclusion.

If you're relying on the libraries on your system, you're likely to end up with problems. Try building with static ffmpeg, and then you'll download and build a more recent version - that's what will appear in libav_static in the root of your git clone.

You need to add AUTOBUILD_CONFIGURE_EXTRA="--enable-libffmpeg_static" if you're building a deb, or otherwise add this to configure ... I run on an Intel 64 platform, so don't know what the options would be, I'm afraid.

I tried to remove all the FFmpeg related libraries and compile them from source. Even the configure scirpt complained there's no libavresample, it generated Makefile and compiled just fine.

Looks like I have the same error. How did you solve it ? (beginner)

I uninstalled all the FFmpeg related libraries (list is on FFmpeg github).

Then I cloned https://github.com/FFmpeg/FFmpeg, `./configure && make`, `sudo make install`. Then I reconfigured Tvheadend ignoring all the errors.

Thanks for the tip, it's working
