Standard Components Library Not Provided

The Standard Components Library is not provided with the HP aC++ compiler for Integrity servers. HP recommends that you use the similar features of the Standard C++ Library in place of the Standard Components Library.

HP C++ (cfront) Complex Library Not Supported

The Complex library which is part of the cfront based HP C++ compiler product is not included with HP aC++. HP recommendeds that you use the similar features of the Standard C++ Library in place of the Complex library.

Complete the following procedure to begin migration:

1.Replace #include with <complex>.

2.Remove -lcomplexfrom the command-line.

Manpages

The following manpages describe the complex library are not part of the HP aC++ product. These manpages are no longer available.

•CPLX.INTRO(3C++) - Introduction to The C++ Complex Mathematics Library

•cartpol(3C++) - Partesian and Polar Functions

•cplxexp(3C++) - Exponential, Logarithm, Power, and Square Root Functions for Complex Numbers

•cplxerr(3C++) - Error Handling Function

•cplxops(3C++) - Complex Number Operators

•cplxtrig(3C++) - Trigonometric and Hyperbolic Functions for Complex Numbers

Header File

The Complex library uses the complex.h header file.

HP C++ (cfront) Task Library Not Supported

The task library, that is part of the HP C++, is not included with HP aC++. To develop multi-threaded applications with HP aC++, use the pthreadprogramming interface routines that are available as part of HP DCE/9000.

Manpages

The following manpages describe task library features are not part of the HP aC++ product. These manpages are no longer available.

•TASK.INTRO(3C++) - Introduction to the C++ Task Library

•interrupt(3C++) - Signal Handling

•queue(3C++) - Queue Routines for Message Passing and Data Buffering

•task(3C++) - the C++ task library

•tasksim(3C++) - Histograms and Random Numbers for Simulations with C++ Tasks

Migration Considerations Related to Preprocessing

The HP C++ (cfront) compiler provides ANSI mode (the default) and K&R compatibility mode preprocessing. HP aC++ preprocessing complies with the ANSI/ISO C++ International Standard. Therefore, if you are migrating from cfront ANSI mode preprocessing to HP aC++, in general, no changes are required.

HP aC++ does not support K&R compatibility mode preprocessing.
