So the only missing piece is $(mysql_config --libs) option to the libnetsnmptrapd.so.31.0.2's linker command. Obviously upstream thinks that plugins does not need explicit linkage <https://sourceforge.net/p/net-snmp/bugs/1563/>. I think this is a bug in net-snmp build script.

patch with solution
That patch really doesn't seem like the right way to fix this. The only way I can think it might work is that it effectively results in that definition of LIBS getting 'leaked' out of the configure step, such that *everything* in the entire build process likely winds up getting linked against libmysqlclient / libmariadb . Wouldn't a more appropriate fix be to change the rule for libnetsnmptrapd.$(LIB_EXTENSION)$(LIB_VERSION) in apps/Makefile.in ? Created attachment 1301954 [details]
better patch
I think this patch is more correct; it adds MYSQL_LIBS to the linking of libnetsnmptrapd. The other patch results in 21 occurrences of -lmariadb in the build process, including linking some libraries against libmariadb that do not *need* to be linked against it at all; this patch results in 8 occurrences of -lmariadb , but still fixes the bug (at least, the ldd command no longer reports any unresolved symbols).
Filed upstream https://sourceforge.net/p/net-snmp/bugs/2792/ with my patch. I'm doing a Fedora Rawhide build with my patch, too.
