Re: [Bug-readline] rl_bind_key does not work on Mac OSX

[Ryo Tomidokoro]

Hi, Chet

Thank you for your reply.

I tried following, and still rl_bind_key does not work.

1. Remove existing readline (editline) header files from /usr/include. 

2. Change complie option as below

gcc -I/usr/local/Cellar/readline/6.3.6/include -lreadline sample.c

3. Check include order with gcc -v option

$ gcc -I/usr/local/Cellar/readline/6.3.6/include -lreadline sample.c -v

You're probably not getting the homebrew version of readline you just
installed unless you use -L to specify the homebrew installation lib
directory.

Apple ships a crippled version of "readline" they derived from BSD
editline in /usr/lib, and that's what you get with -lreadline.
