Version: git-master Keywords:
Cc: Blocked By:

Description

Summary of the bug:
Various undefined references on linking.

How to reproduce:
I did exactly as described in "Compile FFmpeg for Ubuntu, Debian, or Mint" (https://trac.ffmpeg.org/wiki/CompilationGuide/Ubuntu).

This is the output part where the errors start:

Please confirm that you test current FFmpeg git head, provide your configure line, gcc -v output, run make V=1 ffmpeg twice in a row and provide the console output of the second (!) run to make this a valid ticket.

comment:2 Changed 8 days ago by kybos

Thanks.
As I wrote, I do exactly as described in the docu, which implies the download of the current ffmpeg snapshot, if I understand it correctly.

My input:

cd ~/ffmpeg_sources && wget -O ffmpeg-snapshot.tar.bz2 https://ffmpeg.org/releases/ffmpeg-snapshot.tar.bz2 && tar xjvf ffmpeg-snapshot.tar.bz2 && cd ffmpeg && PATH="$HOME/bin:$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" --extra-libs="-lpthread -lm" --bindir="$HOME/bin" --enable-gpl --enable-libaom --enable-libass --enable-libfdk-aac --enable-libfreetype --enable-libmp3lame --enable-libopus --enable-libvorbis --enable-libvpx --enable-libx264 --enable-libx265 --enable-nonfree && PATH="$HOME/bin:$PATH" make && make install && hash -r

What do the following show?

$ nm libavutil/log2_tab.o
$ nm libavutil/libavutil.a |grep ff_log2_tab

comment:5 Changed 8 days ago by kybos

$ nm libavutil/log2_tab.o
0000000000000000 R ff_log2_tab
$ nm libavutil/libavutil.a |grep ff_log2_tab

comment:6 Changed 8 days ago by cehoyos

Do you have other files libavutil.a or libavutil.so in your file system?

comment:7 follow-up: Changed 8 days ago by kybos

Yes, there are the files from my normal ffmpeg installation:

/usr/lib/x86_64-linux-gnu/libavutil.a

/usr/lib/x86_64-linux-gnu/libavutil.so
/usr/lib/x86_64-linux-gnu/libavutil.so.55
/usr/lib/x86_64-linux-gnu/libavutil.so.55.78.100

Replying to kybos:

Yes, there are the files from my normal ffmpeg installation:

/usr/lib/x86_64-linux-gnu/libavutil.a
/usr/lib/x86_64-linux-gnu/libavutil.so

Does linking work if you rename these two?

comment:9 Changed 7 days ago by kybos

Unfortunately not, exactly the same error as before.

I renamed them so, I assume this should be sufficient:

sudo mv /usr/lib/x86_64-linux-gnu/libavutil.a /usr/lib/x86_64-linux-gnu/libavutil.a.bu
sudo mv /usr/lib/x86_64-linux-gnu/libavutil.so /usr/lib/x86_64-linux-gnu/libavutil.so.bu
