Hi,
Thanks for reply.
I describe my work again.
I cross compiled net-snmp-5.1.1 successfully.
My cross compile procedure:
step 1: ./configure --target=mips-linux --with-cc=mips2_fp_be-gcc --host=mips
--with-endianness=big --prefix=/not/usr/ --with-install-prefix=/tmp
step 2: make
step 3: make install
step 4: cd /tmp
step 5: tar cvf net-snmp-target.tar not
step 6: Then copy the tar file to my target, and on my target
step 7: cd /
step 8: tar xvf net-snmp-target.tar
But when I loaded wpWlsCore.so and wpWlsBridge.so, I got following error
message:
/not/usr/sbin> ./snmpd -f -L -DwpWlsCore,dlmod
dlmod: register mib
dlmod: dlmod_path: /not/usr//lib/snmp/dlmod
dlmod: dlmod_create_module
dlmod: dlmod_load_module wpWlsCoreMIB: /home/wpWlsCore.so
dlopen failed: /home/wpWlsCore.so: undefined symbol: netsnmp_oid_stash_no_free
dlmod: dlmod_create_module
dlmod: dlmod_load_module wpWlsBridgeMIB: /home/wpWlsBridge.so
dlopen failed: /home/wpWlsBridge.so: undefined symbol:
netsnmp_oid_stash_no_free
NET-SNMP version 5.1.1
wpWlsCore.so and wpWlsBridge.so were built against version 5.1.1. I also tried
to load they into version 5.1.1.
I used ldd to check wpWlsBridge.so and snmpd. I am sure needed libraries are
available in my file system.
Why did I get this error? Is it possible that it's a .conf file problem?
I also tried to compile net-snmp on my target with the native gcc, it worked
fine.
So what I missed in my cross compile procedure?
Thanks,
iTAS Tewen

Almost. I had other modules and another symbol.

What version of net-snmp are wpWlsCore.so and wpWlsBridge.so built
against?
What version of net-snmp are you trying to load them into?
Also, what does ldd say about /home/wpWlsCore.so and snmpd?
The error message indicates that there is some problem in resolving
symbols referenced in the dynamic module.
