Re: Getting readline to work in scheme-sandbox

[Knute Snortum]

It looks like I get an error in strace.  The sandbox is never executed:

execve("/home/knute/bin/lilypond", ["lilypond", "scheme-sandbox.ly"],
0x7ffe4792c428 /* 53 vars */) = -1 ENOEXEC (Exec format error)
strace: exec: Exec format error
+++ exited with 1 +++
