What version of libsnmp do you have installed?

Also check build options.  It looks like DES support is now a compile time option.

$ grep -RB1 NETSNMP_DISABLE_DES /usr/include/net-snmp/
/usr/include/net-snmp/net-snmp-config.h-/* Define if DES encryption should not be supported */
/usr/include/net-snmp/net-snmp-config.h:/* #undef NETSNMP_DISABLE_DES */

This is what version I'm compiling against, shown with the net-snmp-config command, on this Linux version I got from uname:

$> net-snmp-config --version

5.9.4.pre2

$> uname -v

 uname -v

#1 SMP PREEMPT_DYNAMIC Debian 6.12.27-1 (2025-05-06)

I tried compiling on a host with a slightly older version of debian, which also compiles okay:

>$ net-snmp-config --version

5.7.3

>$ uname -v

#1 SMP Debian 4.19.316-1 (2024-06-25)

Dear John and EPICS specialist, 

I have the following errors while compiling the SNMP 1.1.0.5.  Could you please help me out? My EPICS version is V7.0.9. Thank you!
