#6089 closed defect (fixed)

libavutil.pc missing some dependencies

Reported by: Mr-Dave Owned by:
Priority: normal Component: avutil
Version: git-master Keywords: pkg-config
Cc: Blocked By:
Blocking: Reproduced by developer: no
Analyzed by developer: no

Description

Summary of the bug:
Some dependent libraries are missing in the package config

How to reproduce:
Build ffmpeg with the following script

cd /home/user/ffmpeg_sources
wget http://ffmpeg.org/releases/ffmpeg-3.2.2.tar.bz2
tar xjvf ffmpeg-3.2.2.tar.bz2
cd ffmpeg-3.2.2

PATH="/home/user/ffmpeg_32/bin:$PATH" PKG_CONFIG_PATH="/home/user/ffmpeg_32/lib/pkgconfig" ./configure \
  --prefix="/home/user/ffmpeg_32" \
  --pkg-config-flags="--static" \
  --extra-cflags="-I/home/user/ffmpeg_32/include" \
  --extra-ldflags="-L/home/user/ffmpeg_32/lib" \
  --bindir="/home/user/ffmpeg_32/bin" \
  --enable-gpl \
  --enable-libass \
  --enable-libfdk-aac \
  --enable-libfreetype \
  --enable-libmp3lame \
  --enable-libopus \
  --enable-libtheora \
  --enable-libvorbis \
  --enable-libvpx \
  --enable-libx264 \
  --enable-libx265 \
  --enable-nonfree
PATH="/home/user/ffmpeg_32/bin:$PATH" make
make install

This results in the following line in libavutil.pc

Libs: -L${libdir}  -lavutil -lm

When linking programs that use ffmpeg, libavutil fails with

collect2: error: ld returned 1 exit status

To work around the issue, revise libavutil.pc to have the following line:

Libs: -L${libdir}  -lavutil -lm -lX11 -lvdpau -lva-drm -lva-x11 -lva


This issue appears to have been introduced in version 3.1
