Corresponding source code
In src/apps/snmp/snmp_mib2_tcp.c, there is an incorrectly placed preprocessor directive that cause an error if LWIP_HAVE_INT64 is not defined. The erroneous code starts at line 598
Current:
598 &SYNC_NODE_NAME(tcp_HCInSegs).node.node,
599 #if LWIP_HAVE_INT64
600 &SYNC_NODE_NAME(tcp_HCOutSegs).node.node,
601 &SYNC_NODE_NAME(tcp_ConnectionTable).node.node,
602 #endif
Should be:
#if LWIP_HAVE_INT64
&SYNC_NODE_NAME(tcp_HCInSegs).node.node,
&SYNC_NODE_NAME(tcp_HCOutSegs).node.node,
#endif
&SYNC_NODE_NAME(tcp_ConnectionTable).node.node,
tcp_HCInSegs and tcp_HCOutSegs are defined only if LWIP_HAVE_INT64 is true in lines 522-525 of the same file, so we get an error that tcp_HCInSegs has not been declared.
