Of course that doesn't compile. A numeric value is expected.
./configure --with-pty-mode=0620 --with-pty-group=$(getent group tty|cut -f 3
-d :)
is closer to what also the default for screen-5.0.0 configure is.
AC_ARG_WITH(pty-mode, AS_HELP_STRING([--with-pty-mode],
[set pty mode (default: 0622)]),
[with_pty_mode=$withval],
[with_pty_mode=0622])
AC_ARG_WITH(pty-group, AS_HELP_STRING([--with-pty-group],
[set pty group (default: 5)]),
[with_pty_group=$withval],
[with_pty_group=5])
Which brings me to the question if it is really smart to hardcode the
numeric group ID. I observe wildly changing system user/group IDs in
distros that create the accounts on the fly when installing packages.
Maybe tty is always present on install images already … and happens to
always be numeric ID 5, everywhere?
Alrighty then,
Thomas
