TITLE : tools.h++ from Rogue Wave conflicts with Turbo Vision




Tools.h++ from Rogue Wave conflicts with Turbo Vision.

The header file defs.h from Rogue Wave Tools.h++ contains these
lines:

// The following is for your convenience and can be removed
// if it conflicts with some other package:
#define Boolean RWBoolean

If you are using Tools.h++ with Turbo Vision, it will lead to
conflicts since TV has the following definition for Boolean:

enum Boolean { TRUE, FALSE };

Commenting out the #define in defs.h from Tools.h++ resolves the
conflict.

In the case where this was initially encountered, a virtual
function being redefined in a derived class was seen by the
compiler to have a different signature. Thus, instead of being a
redefinition, it hid the base class function. Then a call to
(baseClass*)->virtualFunction got the base class function instead
of the intended derived class' version.
