You need to tell the compiler where to look for the includes and libraries.
On arch linux, it's /usr/lib and /usr/include. However, this didn't work for me, as I think in the latest version of libavcodec the deprecated function avcodec_open has been removed.
g++ -o untrunc file.cpp main.cpp track.cpp atom.cpp mp4.cpp -I/usr/include -L/usr/lib -lavformat -lavcodec -lavutil
I had to change it to use the ones that seem to be provided with ffmpeg-compat.
So install ffmpeg-compat, and then the following should work (or at least it did for me).
g++ -o untrunc file.cpp main.cpp track.cpp atom.cpp mp4.cpp -I/usr/include/ffmpeg-compat -L/usr/lib/ffmpeg-compat -lavformat -lavcodec -lavutil
Unfortunately untrunc wasn't able to fix my friend's mp4. It got it playing with just audio and no video.

Any tips on getting around the avcodec_open problem on Debian?
UPDATE: Nevermind, I looked at some of the other issues and am now trying thye manual installation of libav.

Did you manage to install on Debian?
I am getting these errors:
