Hi, I just did `make -j5 CPU_COUNT=5` with some experimental patch on top of current master. It failed with lilypond-book.py: error: file not found: single-staff-template-with-notes-and-lyrics.ly This file _is_ present, I checked this! Without changing anything I did `make -j5 CPU_COUNT=5` again. Success!
What's going on? Thanks, Harm
