Crapp... I only gave you part of the information you needed.
Add the following to the end of config.h. A good place is after the
__MWERKS__ tests to set CRYPTOPP_DLL:
#if __GNUC__ >= 4
#undef CRYPTOPP_DLL
#define CRYPTOPP_DLL __attribute__ ((visibility ("default")))
#endif
Here's the result on a Ubuntu test machine:
cryptopp$ nm -D libcryptopp.so | c++filt | grep Filter::Filter
00000000001b06e6 T
CryptoPP::Filter::Filter(CryptoPP::BufferedTransformation*)
00000000001b06e6 T
CryptoPP::Filter::Filter(CryptoPP::BufferedTransformation*)
