Hi All
I've compiled kamailio 3.2.0 with snmpstats module.
When trying to start the module I received the following message:
0(28197) DEBUG: <core> [sr_module.c:515]: load_module: trying to load
</usr/lib/kamailio/modules_k/
snmpstats.so>
0(28197) ERROR: <core> [sr_module.c:523]: ERROR: load_module: could not
open module </usr/lib/kamailio/modules_k/snmpstats.so>:
/usr/lib/libnetsnmpagent.so.10: undefined symbol: boot_DynaLoader
I run it on CentOS 5.7
After digging Internet, I found the solution for the problem. I had to
modify Makefile in snmpstats module's directory and recompile it.
I had to change BUILDAGENTLIBS env param
before change:
BUILDAGENTLIBS =-L$(LOCALBASE)/lib -lnetsnmpmibs -lnetsnmpagent \
-lnetsnmphelpers -lnetsnmp
after change:
BUILDAGENTLIBS =-L$(LOCALBASE)/lib -lnetsnmpmibs -lnetsnmpagent \
-lnetsnmphelpers -lnetsnmp \
-Wl,-E
-Wl,-rpath,/usr/lib/perl5/5.8.8/i386-linux-thread-multi/CORE \
-L/usr/local/lib
/usr/lib/perl5/5.8.8/i386-linux-thread-multi/auto/DynaLoader/DynaLoader.a \
-L/usr/lib/perl5/5.8.8/i386-linux-thread-multi/CORE \
-lperl -lresolv -lnsl -ldl -lm -lcrypt -lutil -lpthread -lc
\
-lwrap \
-lsensors \
-lrpmdb -lrpm
After that I successfully started snmpstats module.
I don't know why I didn't have compilation errors before adding this
linking info, but got problem when trying to run compiled module. Can you
explain it ?
Do you know another way to solve the problem ?

the error is due to missing linking
to some libraries, thus is not a
compile time error, but a runtime loading problem. The solutions is to
find missing libraries at link time and add them as you did.
In this case, in many OS-es, the net-snmp library comes with a tool
named net-snmp-config that can list the lib dependencies. That is used
in makefile when found on the system, but seems in your case does not
exist. Can you check somehow if the tool is provided by another package
on centos 5.7?
In other OSes, there is a pkg-config tool that can do more or less the
same. You can check if you have it on your centos and if yes, check if
can print dependencies for net-snmp:
pkg-config --list-all
should list all supported packages.
Cheers,
Daniel
