Re: question on AgentX sub-agent logging

Thanks

Compile OK now. I still have link error: 
"undefined reference to `setup_log'".

Here is what my Makefile looks like:


BUILDAGENTLIBS=`net-snmp-config --agent-libs`

sub-agent: $(OBJ)
        $(CC) -o sub-agent $(OBJ)  $(BUILDAGENTLIBS)

Am I missing some library in order to use setup_log?

Steve
