Re: Getting readline to work in scheme-sandbox

[Knute Snortum]

I'm not in a vanilla setup, so I changed the commands to: (just for posterity)

$ export 
LD_LIBRARY_PATH="/home/knute/lilypond/lilypond-2.19.83/lilypond/usr/lib"
$ strace -o readlinedebug.log
/home/knute/lilypond/lilypond-2.19.83/lilypond/usr/bin/lilypond
scheme-sandbox.ly

The log file is attached.
