Experimental Physics and
Industrial Control System

I solved the issue and compiled the IOC.  It required commenting out
the function declaration and prototype for the syslog function in
LVWienerPL5xxApp/src/lib/source_v12.c (or whichever version of this
file you use) and WIENER_SNMP.h.  I also ensured that there was an
appropriate link to libnetsnmp.so (libnetsnmp.so.30 in my case).
