I've just run convert-ly on a 600+ line file and its \include files, from 2.19.40 to 2.25.0. Nothing seemed to change apart from the \version statement, but on trying to compile the file, I get:
Processing `/tmp/....ly' Parsing...ERROR: In procedure %resolve-variable: Unbound variable: % Exited with return code 1. Does this point to an obvious problem? Before I start laboriously bisecting the file, is there a way to get an error message that points to one or more lines of code in the file? Grateful for any help -- Graham
