Description Kenneth Porter 2004-05-22 16:31:07 UTC
A 3rd party app I'm using, Lugaru Epsilon (http://www.lugaru.com/)
fails to spawn a process buffer. An strace reveals that it can't open
/dev/ptyp0 and friends. The nodes exist but report "no such device"
when I attempt to cat them.

If I've read everything right, these are "BSD" pty's and the default
FC2 kernels have them disabled.

Comment 1 Kenneth Porter 2004-06-09 06:08:45 UTC
The Epsilon author reports that he's added SysV pty support to come in
the next update. Meanwhile, I built a kernel with "legacy pty" support
and the process buffer in Epsilon is again working.

I unpacked the stock kernel SRPM, edited the desired .config file in
SOURCES, edited the SPEC file to add a custom suffix to the revision
string, and rebuilt the binary RPM. The only funny bit is that one has
to define a config variable to set the number of PTY's that's not
"unset" in the default file, so it's useful to run "make config" once
to get the syntax right for setting that variable right.

Here's the edit for i686:

< # CONFIG_LEGACY_PTYS is not set

Here's the edit for the SPEC file:

< %define release %(R="$Revision: 1.358 $"; RR="${R##: }"; echo
> %define release %(R="$Revision: 1.358 $"; RR="${R##: }"; echo

Epsilon 12.06 with SysV PTY support is now available at the Lugaru
website. (See above.)

Feel free to close this with a wontfix. (I entered this as an FYI to
others looking for a solution.)
