It seems you need to link check_icmp with additional libraries to reach
the functions you need.
Do like this;
for i in `grep -l sendto /lib/*.so /usr/lib/*.so | sed -e 's,^.*/lib,,'
-e 's/\..*//'`; do gcc check_icmp -o check_icmp -l$i; done
That will try linking with all libraries that have a symbol called
sendto in them (or one referring to it, compiled with debugging
support). If that doesn't help I'll need more info about the system.
Most likely someone else on this list is more experienced with solaris
than I am, so they might be able to help you.
