This is not surprising: if you look into these files, you'll see that
they only contain an identifier:
instrumentName = {music...}

These are the individual instrumental parts, the main score is in
QuartetOpus18_No4_1.ly, and includes them to print the conductor.

By the way, this score has been typeset with version 2.7.40 ; though
the score looks simple enough to compile correctly, you can use
convert-ly to update it. Or you can also install an old version of
LilyPond, to be found here:

hope this helps!
