Re: Getting readline to work in scheme-sandbox

[Michael Käppler]

This is weird. Seems that strace does not recognize the shebang in the
lilypond script.
Could you please to try to execute the steps in the startup script directly?
I assume you used the vanilla lilypond installer and installed to your
home directory
/home/knute/:

export LD_LIBRARY_PATH="/home/knute/lilypond/usr/lib"
strace -o readlinedebug.log /home/knute/lilypond/usr/bin/lilypond
scheme-sandbox.ly
