Re: [Chicken-users] readline egg (OS X 10.6.6 / Chicken 4.6.0)

[David Dreisigmeyer]

This version of Chicken is not from Macports, but readline is.  I had
tried various CSC_OPTIONS in my .profile, e.g.:

export CSC_OPTIONS="-L/opt/local/lib -I/opt/local/include"
export CSC_OPTIONS="-L/opt/local/lib -I/opt/local/include/readline"

and also using the -rpath flag after your suggestion.  None of these
worked though, and I always received the error:

Error: This extension requires GNU readline.  GNU readline may be
found at ftp://ftp.gnu.org/pub/gnu/readline
For more information, please consult
http://chicken.wiki.br/readline#Installation%20problems.
