Disregard my advice for using the -G option, that option is for shared
libraries and likely just deferred the missing symbol until load time.  Let
me take another look at the problem.  The loadmap shows that the symbol is
referenced by operations_test.o (likely in samp.o in your case), but no
definition for the symbol exists.
