libg++

3.3 Release Notes:
libg++

This file contains release notes for the initial release with NEXTSTEP of the GNU C++ class library (libg++ version 2.3).

Example

A simple test program would be:

#include <stream.h>

main()
{
cout << "Hello World!\n";
}

Compile this program with the following command:

cc++ test.cc -o tst -lg++

Running tst would output:

Hello World!

Using genclass

The genclass script generates libg++ class definitions for user consumption. Typically, to generate a linked list of strings, one would use:

genclass String ref defs

to generate String.defs.h, and

genclass String ref SLList

to generate String.SLList.h and String.SLList.cc, which provide the definition and implementation of StringSLList class.

Notes Specific to Release 3.2

The compiler has been updated to look for included header files in /NextDeveloper/Headers/g++ when the compiler is invoked on a C++ file. This eliminates the hassle of using the -I option every time a C++ source file is compiled. The original GNU source has been compiled and a subset of the header files have been massaged for NeXT compatibility. Those specific header files, located in /NextDeveloper/Headers/g++, are:

fcntl.h regex.h strings.h

libc.h stdio.h time.h

math.h stdlib.g unistd.h

memory.h string.h values.h

sys/socket.h sys/time.h sys/times.h

Note that the last three headers, located in the g++ include directory, cover the functionality of the "standard" headers included by the same name; that is, #include <sys/socket.h> in a C++ file would use the file in /NextDeveloper/Headers/g++ rather than the standard UNIX file.
The stream manipulators declared in the file /NextDeveloper/Headers/g++/iomanip.h are not supported due to the lack of support for templates in gcc in the current version of NEXTSTEP.

fcntl.h	regex.h	strings.h
libc.h	stdio.h	time.h
math.h	stdlib.g	unistd.h
memory.h	string.h	values.h

sys/socket.h	sys/time.h	sys/times.h
