Hi,
We recently switched from gcc 2.8.1 to gcc 3.3. When compiling, I get the following errors:
I'm sorry, but without seeing a short but releveant code example, one can only guess why.
The streams library shipped with 3.3 aims for compliance with the 1998 ISO C++ standard. It is radically different from the 1990 ARM C++ streams library 2.8.1 shipped with. If your code makes much use of custom stream buffers and such, you're in for some work.

Why are you instantiating a basic_ostream on char and NamedData? If NamedData is a traits class, it needs typedefs for pos_type, int_type, and off_type. If it isn't a traits class, it doesn't belong in basic_ostream's parameter list.

There are no types int_type, pos_type and off_type in class NamedData or in any of our files. How do I get rid of these errors? I've played but to no avail. These errors did not occur in 2.8.1.

2.8.1 did not have a basic_ostream class template at all. So I don't think these errors are simply due to migration - something else must have been changed as well. (Possibly, you were using a 3rd-party implementation of the standard library?)
