Problem building net-snmp 5.3.1 rc2 on RHEL4 64bit

[mshields at namemedia.com (Matt Shields)]

Just so everyone knows, the default net-snmp that ships with redhat
5.1.2 does not support 64 bit counters, it wasn't introduced till 5.2.1.
The latest version 5.3.1rc2 has compile problems on RHEL4 x86_64.   But
I was able to compile 5.2.2 and get 64 bit counters to work.  See this
thead: https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=158630

When you do a compile use the --enable-mfd-rewrites flag.

I've had problems getting 64 bit counters working with RedHat's net-snmp
and have been successful with 5.3.1 on all my other servers.  I've
compiled this no problem on those, but they're all 32 bit.  Now we're
starting to get 64bit servers in, so one way or another it would be nice
to get this working with 5.3.1.  Also, if we don't use 64 bit counters,
we rollover about every minute or so for our bandwidth statistics.

I did try applying one of the patches that refers to the libtool, but
that didn't work.

Hi Matt,

Yes, you're likely encountering a multilib issue.  But the real question
you should be asking yourself is: why compile net-snmp from source?

If you really do need to build from source (say, for a newer version)
then I suggest that you grab one of the SRPMs and rebuild using it as a
starting point since there are a handful of patches that Red Hat has
applied in order to straighten out things such as the multilib/libtool
issue.

You can see for yourself with the Centos SRPMs:

  wget
http://ftp.telus.net/pub/centos/4.3/os/SRPMS/net-snmp-5.1.2-11.EL4.6.src
.rpm
  rpm2cpio net-snmp-5.1.2-11.EL4.6.src.rpm | cpio -ivd
  more more net-snmp.spec
