I have two stretch systems, named deb4 and deb9. Both were installed via netinst, have the latest apt update; apt upgrade, and report:
$ uname -v #1 SMP Debian 4.9.82-1+deb9u3 (2018-03-02) Several attempts to install ffmpeg on deb9 have appeared to succeed, but ffmpeg with various options consistently reports: ffmpeg: error while loading shared libraries: libopenal.so.1: cannot open shared object file: No such file or directory On the other system, deb4, ffmpeg installed and ran immediately and was successfully used to split a .mov file into two parts. /etc/apt/sources.list is the same on deb4 and deb9. I have compared the package versions on deb9 with those on deb4 and they are the same. Before reinstalling ffmpeg on deb9 I ran: # apt purge ffmpeg # apt autoremove # apt install ffmpeg I've run ldconfig and repeated the above. STW, I've set LD_LIBRARY_PATH=/usr/local/lib and repeated. Also tried: # apt search openal ...and saw that it contains libopenal.so.1 but: # apt install openal E: Unable to locate package openal What do I need to do to figure out what's wrong with deb9? - Dan
