X windows/Motif with DECnet

[Diane Durbeck]

On our DS5000 running Ultrix 4.1, we have compiled and installed MIT's X11R4.18+
and the latest Xt patch from OSF to support Motif v1.1.1 .  All of the MIT
X clients and our own X applications operate fine under TCP/IP.  To operate
under DECnet protocol, we know to link in the DECnet library (-ldnet).
However, we still cannot run under DECnet.  The X system-derived error states 
that it is unable to open the display and XtOpenDisplay returns a NULL.

Does the '-ldnet' argument to 'ld' need to be placed before the X libraries
or after?  Does it even matter?  We have tried all placement strategies
with still no success.

When compiling the MIT X source, we noticed that there are defines for 
TCPCONN and UNIXCONN that should be turned on for TCP/IP and socket support,
respectively.  But we could not find an analogous define for DECnet (as in 
DNETCONN).  Is there one?  Did we overlook something?

Any help would be much appreciated.
