I've just been through this process, trying to build the shared
libraries for UIT and SlingShot (Xview C++ and graphics support
routines respectively).  The process is straightforward, but I had to
'dig' to learn how.  Basically, it goes like this:

	1	Compile with -fpic to .o files
	2	Create an archive with 'ar' to make the .a static library 
	3	Run 'ld -shared' to build the shared library
	4a	Copy the libraries and set permissions
	4b	Set up any soft links for the shared libraries (for examples,
		look in /usr/X11R6/lib)
	5	Run ldconfig to set up 'ld.so's cache

The last step makes them visible when linking your applications.

Good luck.
