Hi,
CINT removed the namespace std by default. You have two options: build
CINT with -DG__STD_NAMESPACE (which is not exercised regularly and might
thus fail) or create a new header that's only used for the dictionaries
and which contains nothing but "namespace std{} using namespace std;"
You pass it to cint together with the actual headers when creating the
dictionary. That way your program will not use it, only the CINT
dictionaries will #include it.
Cheers, Axel.
