Hi

I use OpenBSD 6.4 (amd64) with ruby 2.5.3p105

All code that use PTY module doesn't work, i get RuntimeError(can't get Master/Slave device).

In a console IRB :

require 'pty'
==>true
master, slave = PTY.open
Traceback (most recent call last):
3: from /usr/local/bin/irb:11:in <main>' 2: from (irb):2 1: from (irb):2:in open'
RuntimeError (can't get Master/Slave device)

I can provide you ssh access to OpenBSD if you need.

Thank you very much.

• File 0001-Fix-PTY.open-on-OpenBSD.patch 0001-Fix-PTY.open-on-OpenBSD.patch added
• Backport changed from 2.4: UNKNOWN, 2.5: UNKNOWN, 2.6: UNKNOWN to 2.4: REQUIRED, 2.5: REQUIRED, 2.6: REQUIRED

Attached is a fix to this issue, by just adding || defined(__OpenBSD__).

The example in the PTY document works correctly with this patch.
