DESCRIPTION

Compaq C++ for Tru64^tm UNIX® is a native programming language product, which generates optimized object code without employing an intermediate translation to C. Compaq C++ for Tru64 UNIX is based on the ANSI/ISO C++ International Standard, reference designation number ISO/IEC 14882:1998. In addition to this standard, C++ supports the ARM, CFRONT, GNU, and MS dialects. Compaq C++ used along with the Developers' Toolkit for Tru64 UNIX and Compaq FUSE offers application developers a complete C++ development environment.

Compaq C++ includes:

• The native Compaq C++ compiler, which implements most features of the ANSI/ISO C++ International Standard. Compaq C++ includes support for automatic instantiation of templates, precompiled headers, and C++ exception handling.
• The highly optimizing, reliable Alpha code generator for speed of generated code.
• The C++ Standard Library, which is an implementation of the ANSI/ISO C++ Standard Library. This library is comprised of a suite of header files and the run time code needed to implement the string library, numeric limits, auto pointer, exceptions, complex math, and the STL (Standard Template Library). Portions of the C++ Standard Library have been implemented using source licensed from and copyrighted by Rogue Wave Software, Inc.
• The DEC C++ Class Library, which is a set of headers and other files implementing a collection of basic C++ classes that are identical to those provided with previous versions of the compiler. This library is provided to support software developers using Compaq C++ Version 6.3A with software developed previously.
• Features to facilitate porting between Compaq C++ and other implementations of the C++ language. The compiler allows you to choose from several C++ language dialects that have evolved over the past several years:
  • the ms dialect for maximizing compatibility with Microsoft's Visual C++ product.
  • the cfront dialect for compatibility with the AT&T cfront translator.
  • the gnu dialect for compatibility with the g++ compiler.
  • the arm dialect for compatibility with The Annotated C++ Reference Manual by Ellis and Stroustrup. Using this dialect minimizes the source changes necessary for applications that compile with DEC C++ Version 5.6.
  • the strict ANSI dialect for developers who want to write applications that comply with the C++ International Standard.
• A tool to decode compiler-generated names, that enables other tools (besides the compiler and debugger) to present these decoded names to the user.

Application developers using Compaq C++ are required to purchase a license for the Developers' Toolkit for Tru64 UNIX. This product provides a set of UNIX development tools that include: a symbolic source-level debugger (Ladebug), ATOM based performance and analysis tools, program analysis tools (profiling and performance analysis), two ANSI conformant C Compilers (including Compaq C for Tru64 UNIX), reordering tools (cord, feedback, and runcord), and the Porting Assistant, which aids in porting to Tru64 UNIX from other UNIX platforms and from OpenVMS Systems. For further information on these products, please see SPD 44.36.

The Ladebug debugger provides basic debugging capabilities as well as specific support for the C++ language, including function name and operator overloading, C++ scoping, templates, C++ exception handling, multiple inheritance, virtual base classes, and virtual functions. Both window-based and dbx-style command-line interfaces are provided. C++ debugging on Tru64 UNIX is not supported by dbx, only by Ladebug.

Application developers interested in an integrated, graphical, GUI-based, extensible development environment may be interested in purchasing licenses for Compaq FUSE and the Compaq FUSE C++ Support option. For more information, please see SPD 44.71.

For more information on the Developers' Toolkit, C Developers' Extensions and Compaq FUSE, please see the Optional Software section below.

Compaq C++ supports the Tru64 UNIX features of shared libraries and 64-bit computing.

The Compaq C++ documentation provides comprehensive reference and usage information for all product components. Online reference pages (man pages) are provided with the software, and browser-based (HTML) documents are provided on the Layered Products Documentation CD-ROM for the following manuals:

• Using Compaq C++ for Tru64 UNIX
• Compaq C++ Installation Guide for Tru64 UNIX
• Compaq C++ Class Library Reference Manual

HTML files are provided for the release notes and some of the product manuals for use with a web browser.

Hardcopy documentation is available by ordering the separate software documentation kit. The hardcopy documentation kit also includes a copy of an authoritative book on C++, The C++ Programming Language, 3rd Edition, by Bjarne Stroustrup.
