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.

Try and remove the 32 bit libs if you are not running 32 bit apps.

# rpmbuild -tb snmppd-0.5.2.tar.gz

You are building 64 bit, but it is finding the 32 bit libs and bombing.

searching for -lnetsnmp
/usr/bin/ld: skipping incompatible /usr/lib/libnetsnmp.a when

Same here. 64 bit libs are in /usr/lib64 .

searching for -lnetsnmp
snmppd.o: In function `new_target':
snmppd.c:(.text+0x371): undefined reference to `split'

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

you notice quickly if they don't!!!!

It is very difficult to build 64 bit software when 32 bit libs are present because the 32 bit lib path gets searched first.
