critical impact:

C++ compiler -D__USE_STD_IOSTREAM and -D__NO_USE_STD_IO_STREAM command options - not available (CrUn343)

Problem description

The -D__USE_STD_IOSTREAM and -D_NO_USE_STD_IOSTREAM command options are supported on Tru64 UNIX, but not on HP-UX.

The -D__USE_STD_IOSTREAM option forces the inclusion of the ANSI standard version of the <iostream.h> header file. This is the default in strict_ansi and strict_ansi_errors modes of the compiler.

The -D__NO_USE_STD_IOSTREAM forces the prestandard version of iostreams to be used. This is the default on Tru64 UNIX.

Identifiers

Solution description

Use the -AA option as a replacement for the Tru64 UNIX -D_USE_STD_IOSTREAM to force the standard version of iostream.

Use the -AP option as a replacement for the Tru64 UNIX -D__NO_USE_STD_IOSTREAM to use the prestandard version of iostream.

On HP-UX on Itanium®-based systems, the standard iostream option (-AA) is the default.

See the Tru64 UNIX to HP-UX 11i Porting Guide for more information.
