12.2.1 C++ Library Descriptions

A brief description of each of these libraries follows.

• libCrun: This library contains the runtime support needed by the compiler in the standard mode (–compat=5). It provides support for new/delete, exceptions, and RTTI.

  libCstd: This is the C++ standard library. In particular, it includes iostreams. If you have existing sources that use the classic iostreams and you want to make use of the standard iostreams, you have to modify your sources to conform to the new interface. See the C++ Standard Library Reference online manual for details. You can access this manual by pointing your web browser to:

file:/opt/SUNWspro/docs/index.html

If your compiler software is not installed in the /opt directory, ask your system administrator for the equivalent path on your system.

• libiostream: This is the classic iostreams library built with– compat=5. If you have existing sources that use the classic iostreams and you want to compile these sources with the standard mode (–compat=5), you can use libiostream without modifying your sources. Use– library=iostream to get this library.

  Note –

  Much of the standard library depends on using standard iostreams. Using classic iostreams in the same program can cause problems.

• libC: This is the library needed in compatibility mode (–compat=4). It contains the C++ runtime support as well as the classic iostreams.

• libcomplex: This library provides complex arithmetic in compatibility mode (-compat=4). In the standard mode, the complex arithmetic functionality is available in libCstd.

• libstlport: This is the STLport implementation of the C++ standard library. You can use this library instead of the default libCstd by specifying the option -library=stlport4. However, you cannot use libstlport and libCstd in the same program. You must compile and link everything, including imported libraries, using one or the other exclusively.

• librwtool (Tools.h++): Tools.h++ is a C++ foundation class library from RogueWave. Version 7 of this library is provided with this release. This library is available in classic-iostreams form (-library=rwtools7) and standard-iostreams form (-library=rwtools7_std). For further information about this library, see the following online documentation.

  • Tools.h++ User’s Guide (Version 7)

  • Tools.h++ Class Library Reference (Version 7)

  If your compiler software is not installed in the /opt directory, ask your system administrator for the equivalent path on your system.

• libgc: This library is used in deployment mode or garbage collection mode. Simply linking with the libgc library automatically and permanently fixes a program’s memory leaks. When you link your program with the libgc library, you can program without calling free or delete while otherwise programming normally. The garbage collection library has a dependency on the dynamic load library so specify -lgc and -ldl when you link your program.

  Additional information can be found in the gcFixPrematureFrees(3) and gcInitialize(3) man pages.

• libdemangle: This library is used for demangling C++ mangled names.
