I just downloaded the unofficial 2.20.0 build for Mac (I'm using OS 10.15
"Catalina"). And I am unable to process the simplest file because I get an
error from the lily-library.scm Scheme file: Wrong type (expecting real
number): #<undefined>.
I've searched for this error online and I am unable to find any helpful
information. Does anyone have an idea how I should proceed?
Here's my script and the error message.
\version "2.20.0"
