PRODUCT : Borland C++ NUMBER : 1398 VERSION : 3.x OS : DOS DATE : October 25, 1993 PAGE : 1/1 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.
