Re: lilypond-book V2.22.0 hanging on Windows 10

[Daniel Connors]

David,

 

Yes, I am running on Windows.  I made sure that no PDF viewer was running and tried running the lilypond-book script and it still hangs.  I even closed emacs to make sure that some file in my emacs buffers wasn't the culprit.  The script is hanging on Windows 10.

Thank you for your suggestion.

Dan

You appear to be running on Windows. A common problem is that Windows
doesn't let you write to a file that another application has open.
So make sure you close out.pdf before you run lilypond-book.
(I don't *think* you have to delete it as well.)
