Feature #2983: Ruby (GPLv2 only) tries to link to with readline (now GPLv3)

Hi,

The readline library was relicensed under GPLv3. Since Ruby is GPLv2 only, it is not allowed to link to readline.

Most distributions currently ship both the (old) GPLv2 readline version, and the new GPLv3 readline. However, this is likely to change in the future.

A solution could be to use a different library, like libedit (http://www.thrysoee.dk/editline/)

libedit doesn't support multibyte encodings.

I'm surprised this was closed without discussion. How do you recommend we (Debian) solve that?

=begin
GPL3 problem is not resolved; this ticket is mistakenly closed because this is duplicated ticket with #2982.

libedit might be finally getting multibyte encodings - http://cvsweb.netbsd.org/bsdweb.cgi/src/lib/libedit/?sortby=date - there appears to be a commit to add UTF-8 support
=end

[naruse (Yui NARUSE)]

=begin
Yes, but current its UTF-8 support is broken.
Moreover it is only UTF-8.

I heard they are working on supporting M17N, so it is good when that is done.

=begin
I close this ticket because it is duplication.
Also, note that libedit has been supported already,
libreadline will be disabled by --enable-libedit configure option.

Don't close duplicated tickets, all of them are closed if you close one of them > nobu

• ruby -v changed from 1.8 to *

=begin
At least, to avoid divergence, I don't think we should make discussions in many places.
