Dear FFmpeg users,
I'm trying to build a fork of ffmpeg under Linux (Ubuntu 14.04, gcc 4.82) which
then integrates the codec I'm working on (https://github.com/bbc/turingcodec).
This codec uses some boost libraries which ship with the source code. However,
when I build ffmpeg enabling the Turing codec (--enable-libturing) I can see
that the executable of ffmpeg links the system's boost libraries. Is there a
way to link to the libraries associated with the Turing codec? I've tried the
--extra-ldflags option but no joy. The way I configure the build is the
following:
PATH="/path/to/source/code/bin:$PATH" PKG_CONFIG_PATH="$HOME/ffmpeg_build/lib/pkgconfig" ./configure
--prefix="$HOME/ffmpeg_build" --pkg-config-flags="--static" --extra-cflags="-I$HOME/ffmpeg_build/include"
--extra-ldflags="-L$HOME/ffmpeg_build/lib-L/path/to/turing/source/code/build/release/boost" --bindir="$HOME/bin" --enable-gpl
--enable-nonfree --enable-libturing
Many thanks for your help!
Best regards,
Matteo
The line with:
--extra-ldflags="-L$HOME/ffmpeg_build/lib-L/path/to/turing/source/code/build/release/boost"
should say:
--extra-ldflags="-L$HOME/ffmpeg_build/lib
-L/path/to/turing/source/code/build/release/boost"
It's missing a blank between the two -L<path> arguments.
