 command stop there,and what  should I do next?


Try to query MIB objects from your module.
That should display any debug output that you've
included in the code.

 /* I really have no idea what its meaning */

This is the default directory where the agent will look for
.so modules to load.   But you specify a full path below,
so don't need to worry about this.


 dlmod: dlmod_create_module
 dlmod: dlmod_load_module uit: /usr/share/snmp/mibs/uit.so

No is error displayed here, so it looks as if the module is
being loaded successfully.


 /etc/snmp/snmpd.conf: line 430: Warning: Unknown token: mibs.

The mibs directive is typically aimed at client applications,
and belongs in the file snmp.conf, not the agent-specific file.


 Error opening specified endpoint 
 Server Exiting with code 1

Typically that would indicate that you're running the
agent as a non-root user, and trying to open the standard
(privileged) port.   Which fails.

But given that you seem to be running this as root,
my suspicion is that you're already running an SNMP
agent, listening on this port.

Either stop this standard agent before running your
new one, or run your testing on a different port
e,g:
snmpd -f -Le -Duit,dlmod   6161


 /* /etc/snmp/snmpd.conf: line 430 is: mibs +ALL is anything wrong? */

This directive belongs in snmp.conf

 I modified a Makefile file for my own use,as follows:

 CC=gcc
 OBJS1=snmpdemoapp.o
 OBJS2=example-demon.o uit.o
 OBJS3=asyncapp.o
 TARGETS=example-demon snmpdemoapp asyncapp
 CFLAGS=-I. `net-snmp-config --cflags`
 BUILDLIBS=`net-snmp-config --libs`
 BUILDAGENTLIBS=`net-snmp-config --agent-libs`
 # shared library flags (assumes gcc)
 DLFLAGS=-fPIC -shared
 all: $(TARGETS)
 snmpdemoapp: $(OBJS1
  $(CC) -o snmpdemoapp $(OBJS1) $(BUILDLIBS)
 asyncapp: $(OBJS3)
  $(CC) -o asyncapp $(OBJS3) $(BUILDLIBS)
 example-demon: $(OBJS2)
  $(CC) -o example-demon $(OBJS2) $(BUILDAGENTLIBS)
 clean:
  rm $(OBJS2) $(OBJS2) $(TARGETS)
 uit.so: uit.c Makefile
  $(CC) $(CFLAGS) $(DLFLAGS) -c -o uit.o uit.c
  $(CC) $(CFLAGS) $(DLFLAGS) -o uit.so uit.o
 Is anything wrong here?
