snmpv3 authentication failure

Hi,

I have been having problems getting snmpv3 authentication of the
passphrase to work, and I have seen a lot of emails from others with
this problem.

I have found that my problem was due to my snmp libraries being built
for my Linux Motorola system with compilation set for little-endian
instead of big-endian.

This affects the authentication key calculations in MD5.c which uses
#ifdef WORDS_BIGENDIAN to alter the byte reading of key data.

How should  I set this define in the build? Do I need to add
-DWORDS_BIGENDIAN to the CFLAGS?

I can see:
ifdef CONFIG_CPU_BIG_ENDIAN
NET_SNMP_CFG += --with-endianness=big
else
NET_SNMP_CFG += --with-endianness=little
Endif

In the top makefile.

I can't see where CONFIG_CPU_BIG_ENDIAN is defined or whether it has any
affect on the define for WORDS_BIGENDIAN.

I am building my snmp within a uclinux distribution. The snmp is V5.2.1.

Regards,

Steve McCarthy
