There is a bug in snmp++v3.2.23 on the planform(Little-Endian; int is 4;
long is 8).
asn_parse_length:
origin:
memcpy((char *)length, (char *)data + 1, (int)lengthbyte);
*length = ntohl(*length);
*length >>= (8 * ((sizeof(int)) - lengthbyte));
Fixed:
uint32_t t = 0;
memcpy((char *)&t, (char *)data + 1, (int)lengthbyte);
t = ntohl(t);
*length >>= (8 * ((sizeof(int)) - lengthbyte));
Becausal the ntohl and the >>= operation handle 64 bit long type.

you can replace the default AgentLogImpl object to send all logging
messages to your own log functions:
- Create your own AgentLog implementation (most likely as a wrapper for
the logging API you're using) (see log.h)
- Call DefaultLog::init(new YourAgentLogImplClass()) before calling any
other agent++/snmp++ function.

Jochen

Hello,
I have problems to understand your mail. For my 64 bit linux system the
line *length >>= (8 * ((sizeof(long)) - lengthbyte)); does the right
thing. And here int is 4 byte and long 8 byte.
Is the line above on your system wrong? Can you enable the debug
messages and send me the error message?
Regards,
Jochen
