Subject: 58)  What are these problems with "_XtInherit not found" on the Sun?
When I run a X program that I wrote on a SunOS 4.0.3 or 4.1 machine I get the 
error "ld.so: symbol not found _XtInherit".

	What you are seeing is a side-effect of a kludge in the R4 libXt.a to 
get Sun shared libraries working.  Apparently, you can't share a function that 
is both called and compared, as _XtInherit is. This was handled by putting 
_XtInherit in the same file as a function that is always used, thereby 
guaranteeing that it would be loaded -- that is, in Initialize.c, where 
XtToolkitInitialize() and XtInitialize() reside. These routines would normally
be called.

	You are probably seeing this error because your program is not a normal
Xt-based program and does not call XtToolkitInitialize() anywhere. 
	1) it may be a program that uses Xt functions but never opens a 
connection to the X server.  [OSF/Motif's 1.1 UIL has this problem; it calls 
XtMalloc() and other Xt functions.] The solution is to add the call to your 
program; the function does not have to be executed, just linked in.
	2) alternatively, your program doesn't need any Xt functions and is
correct in not calling XtToolkitInitialize() -- it may be an Xlib or XView 
program. In this case, you can remove -lXt from your link command. 

	It should not be necessary to link the shared libraries statically,
although this will certainly solve the problem.
