I haven't used Lilypond for a while, but I have currently got v.2.24.1 I started a new, very small, project today, but I can't compile anything. Thinking I must have forgotten even the basics of writing Lilypond files, I tried a few of my previous project files which I have successfully compiled in the past. But nothing will compile.
If I use the bash command line, with, for example, 'lilypond -V file.ly' I get no compilation, and the output is identical to what I get if I just enter 'lilypond' with no option and no file. If I try to compile from Emacs, using Ctrl-C Ctrl-L, I get exactly the same output as above, with "Compilation exited abnormally with code 2 at Sun Mar 24 15:54:38" or similar suffixed. What can possibly be wrong? Lilypond isn't giving me any clues. David
