parent"?

Answer: Most likely, you are linking your libraries in the wrong order.  You
must link -lXm *before* -lXt.

Ken Sall (ksall@cen.com) adds: This same error occurs if you combine Motif and
Athena widgets in the same application. If you link with "-lXaw" before "-
lXm", you get the runtime error. However, if you switch the order of the two
libraries, there is no problem. For example:

cc mothena.c -o mothena -lXm -lXaw -lXt -lXmu -lX11
