Hi Centos Users

I try to compile SNMPPD (SNMP Proxy Daemon) on Centos 5.1 x86_64 with latest patches. Dependencies (like libsplit, net-snmp-libs, net-snmp-devel, net-snmp-libs) are installed, both 32 and 64 Bit.

Can anyone explain me "/usr/bin/ld: skipping incompatible" in plain english ;) How to solve it?

"skipping incompatible" means that ld is skipping over libraries/archives that are the wrong architecture. In this case, ld is skipping 32bit archives while trying to link a 64bit binary. This is all well and good.

You can normally ignore these messages because ld is pretty good and eventually finding the correct libs.

Your problem is the "undefined reference" errors, not the "skipping" warnings. It looks like ld needs a -lsplit or something. I don't see a libsplit in my repo so I can't comment specifically. Make sure you have a x86_64 libsplit-devel (or whatever it is called) installed and watch the output of snmppd's configure carefully.
