Migration Considerations when Using Libraries
The following sections contain information about library migration from HP C++ (cfront) to HP
aC++.
Standards Based Libraries
HP aC++ provides the following libraries that are not part of the HP C++ (cfront) compiler:
• Standard C++ Library
• Tools.h++ Library
• HP aC++ Runtime Support Library
HP recommends that you use these standards based libraries whenever possible, instead of the
cfront compatibility libraries. See Chapter 9: “Tools and Libraries” (page 175) for more information.
