In general, in these cases it is useful if you also mail the error that
the compiler or linker shows you.
BTW, in this case I can give you a hint for the answer: libpqxx doesn't
support wstring. You'll probably be able to get Unicode out, but it'll
have to be retrieved using std::string, not std::wstring, and it will be
UTF-8 encoded. This is just my first guess -- Jeroen may be able to tell
you more.
Cheers,
Bart
