Thanks to Dr. Thomas Blinn who pointed out that I was trying to use a
System V Compatibility function and hence the error
Unresolved:
__sve_p_online
This is a ruotine which I am going to implement in a larger module,
so "psrinfo -v" will not meet my needs. However getsysinfo() will
get me exactly what I need.
Thanks again to those who replied.
