Hi Eli,
Let's say I have a file ClassA.h, that pairs with a file ClassA.cpp
to product a library libClassA.a.
ClassA.h contains the single declaration.
class A {...};
I want to transform it to:
#include "ClassB.h"
class A : public class B {...};
ClassB.h is the header file for a library libClassB.a built from ClassB.cpp
and ClassB.h.
I can clearly link libClassB with libClassA. But how can I bring in the
header file so that it's declarations will be known in ClassA.h. Remember
this is happening during a pass.
Thanks,
David
