Getting readline support on solaris

ruby-talk
1

Hi:

I have readline on my system (sparc 5.8), but I can’t seem to get
it to load after building ruby.

How can I build just the readline extension and
test it to see that it works so I don’t have to
rebuild and install all of ruby?

Thanks

You should be able to cd into the Ruby source, under the ‘ext’
directory. You should see a ‘readline’ directory. cd there and do
“ruby extconf.rb”, and “make” to see what the problem is (if any).

Also, I don’t think readline support comes with 5.8 by default, though
it’s included on the companion CD, IIRC. If you don’t see
libreadline.so in /usr/lib, /usr/local/lib, or /opt/sfw/lib, you likely
don’t have it. There’s always sunfreeware.com, too.

Regards,

Dan

Well duh, don’t I feel stupid.
I was assuming that when ‘false’ was returned by:

require ‘readline’

that it was not loading. But it was loaded.

Yeah, if it wasn’t installed you would get a LoadError. I have to admit
I find it strange that ‘require readline’ returns false instead of
true. Anyone know the reason for this?

i think it returns false only if it has already been required, eg:

~ > ruby -e ‘p require “readline”’
true

~> irb
irb(main):001:0> require ‘readline’
=> false

but i could, as usual, be wrong :wink:

Nope. Your’re correct:

ruby -e ‘p require(“readline”)’
true

Well, duh - I forgot irb automatically loads readline, so that’s why I
got a “false”. :slight_smile:
