FileNotFoundError: [Errno 2] No such file or directory: 'qpdf': 'qpdf

[MikeiLL]

This project is so exciting. I was actually just looking for a lilypond file of Summertime for a student 'cause I was (or thought I was) in a rush. Came across github.com/tj64/org-bandbook, which lead me here.

I'm on a Mac. Ran under python3 -v Python 3.7.7 with the built-in venv: python3 -m venv openbook, cd openbook, source bin/activate, make. Got the above error somewhere in rendering the rock book:

When I moved the docs directory and ran make again, it errored out sooner:

$ make

Using LilyPond 2.19.82. Going to try upgrading and see if that helps.

Same error with Lilypond -v 2.20.0:

 $ make

doing [docs/openbook.pdf]
/Users/mikekilmer/Music/Lilypond/openbook/scripts/wrapper_lilypond.py: stderr is

Running lilypond --loglevel=WARNING --pdf --output=docs docs/openbook.ly works with following two warnings:

warning: compressing over-full page by 1.5 staff-spaces
warning: page 16 has been compressed

I never test on Macs.

So you have two problems here:

• you don't have the qpdf tool I use to reduce the size of the pdf. I don't know how to install it on a mac. I don't use a mac. I'm a linux person.
• you lilypond gives errors which my lilypond does not. This is weird since I use 2.20.0 too. It seems to behave differently on a mac.

What can you do?

• change the parameter "do_qpdf" to "False" in scripts/wrapper_lilypond.py
• change the parameter "stop_on_output" to "False" in scripts/wrapper_lilypond.py

This should fix all of the errors above.

Let me know how this works out.

I added a TODO item to test every release builds on a mac. I don't know when I will get around to doing it though...:)

Ha ha. I hear that. Thank you. I will contribute where I can.
