Re: Failed Compile From Source on Debian 10 i386

Many months ago, I tried to get a Debian 10 backport of net-snmp 5.9.  
Unfortunately, there was zero interest.

Have you tried using the ldconfig tool, for recreating the dynamic 
linker cache, printing it, etc?  Based on what you have, that is what I 
would look at next.  (and LD_LIBRARY_PATH too)

Good luck,
John
