yes. The default is to build both, a static and a shared lib. If you use
"make -f Makefile.linux lib" only the static lib is built.

The config_snmp_pp.h assumes that if a gcc is used, the _r functions are
available. You can change this in the header. You will then get warnings
if you compile snmp++ with threads enabled: Although snmp++ uses a mutex
around the gethostbyname() and gethostbyaddr() functions, if the
application uses its own threads and uses these functions at the same
time, a crash can occur. Luckily these functions are only used in the
Address classes and not called by snmp++ itself. Only if the application
passes host names or requests to get a host name from IP, the address
class uses these functions.

You're not alone: :-(

Some other search results state that is has something to do with inline,
but I will have to read some more, to find a solution.
