Answer: If you use the -pic option you may run out of offset table space. use the -PIC option instead. You may get the message "ld.so: Undefined symbol: __XtInherit" when executing UIL. There is a problem in shared library build when you compare a function variable to a routine name, but don't call the routine. Either, you can build the Xt library nonshared, or you can put a reference to XtToolkitInitialize in the UIL main program (or even include a module that references it). The routine doesn't even have to be called; it just has to be there.Go Back Up
