Are you #including the header which declares MyClass?

Hi.
I am just starting to learn Cocoa and would like to use standard C++
classes from my Objective C/C++ classes.
Is there any known documentation on how to do this, or does anyone
have any pointers?
I tried creating a new object of my C++ class and calling a method on
it in a .m file and received a bunch of errors (including new not
being found).
I then changed my .m file to a .mm file and all of the errors went
away except for one:
"cannot find interface declaration for 'MyClass'"
The code in my .mm file is as such:
m_pMemberVariable = new MyClass();
const unsigned int nRes = m_pMemberVariable->MyFunc();
The second line gets the error. The new allocation in the first line
seems to compile fine.
Do I need to create some sort of bridge class or method?
Thanks,
Jeremy
