A: In version 2.0 and later, NeXT provides a C++ compiler bundled with the extended release software. This includes a port of the GNU G++ compiler which has been extended to recognize Objective-C constructs. The compiler is based on G++ version 1.36.4, which implements version 2.0 of the C++ language, as specified by AT&T. It is distinguished from AT&T's cfront compiler in that it produces "native code" (or machine code) rather than C code. Thus it is faster than AT&T's.\
\
The Objective-C++ compiler consists of the compiler driver (/bin/cc++), the compiler proper (/lib/cc1++), a post-linker (/lib/collect), a symbol “demangler” (/bin/g++-filt), an enhanced symbol table tool (/bin/nm++), and an enhanced profiler (/usr/ucb/gprof++). In addition, the debugger provides support for debugging C++ (see the Debugger release notes).\
\
Interface Builder does not support C++. It generates template code in Objective-C, and its palette objects are Objective-C objects. The Appkit will also continue to be Objective-C based. However, you can integrate Interface Builder nib files and C++ and Objective-C language code together into one program in the NeXT environment. See NextAnswers 584 for details on how to do this. \
\
S
\fc0 upport for C++ is intended to give developers with a significant investment in C++ object classes a migration path to the NeXT development environment. We recommend that you use Objective-C for any application you are developing from scratch. \
\
There is an example located in /NextDeveloper/Examples/Calculator++ which illustrates the integration of Interface Builder nib files, Objective-C source code, and C++ source code into one program.\
