You are absolutely correct. My mistake. Looking at the net-snmp repository, that 'broken' LDFLAGS ordering has been like that for who knows how long. So the 5.4.1 tarball from net-snmp, it's as 'broken' as 5.7.1. Yikes, the makefile.in files for all the tools (i.e. command-line goodies like آ‘snmpwalkآ’) has the same problem.
 
In talking with the original engineer who brought in the net-snmp code, he had to modify every Makefile.in to get it to compile correctly. He also had to rename a global variable to prevent the snmp code from crashing during bring up. The global variable is "Sessions" in net-snmp/snmplib/snmp_api.c. He renamed it to "SessionsNetSnmp", a name much more unlikely to be in conflict with anything.
 
As for the LDFLAGS issue, it appears that it doesn't matter which g++ compiler I use, I get the same result for all of them. So my question still is, why are the {LDFLAGS} after $(LOCAL_LIBS)? Also, does 5.7.1, unaltered, compile correctly for anyone using a g++ compiler? Would changing the order adversely affect anyone not using a g++ compiler? Moreover, if this is a problem for most (if not all) g++ compilers, can't we fix it? I really wanted to use net-snmp, unaltered, but it appears that I cannot, bummer. This means every time we pull in a new net-snmp, someone will have to make the same fixes, over, and over again--like I said, bummer.
 
Thanks,

 
Elicia
