C++ on HP-UX 11.23

[Igor Sovin]

Hi!
What software environment do I need to compile and run C++ (object orinted) programs under HP-UX 11.23?

For example, now I use cc compiler and I get such errors:

Simple program text:
root@lev /home/igorps>more cout.c
#include
void main(){
cout << "Hello, World!\n";
}

root@lev /home/igorps>cc cout.c
Error 112: "cout.c", line 1 # Include file not found.
#include
^^^^^^^^^^^^
Error (future) 355: "cout.c", line 2 # Function 'main' must return type 'int'.
void main(){
^^^^
Error 172: "cout.c", line 3 # Undeclared variable 'cout'.
cout << "Hello, World!\n";
^^^^
Warning: 1 future errors were detected and ignored. Add a '+p' option to detect and fix them before they become fatal errors in a future release. Behavior of this ill-formed program is not guaranteed to match that of a well-formed program

Hi Igor,

You need to have either aCC or GCC to compile C++ programs in HP-UX 11.23. You can download them from these locations,

I've tried to use gcc, but I get other errors.
GCC compiler couldn't find .h files

root@lev /home/igorps>/usr/local/bin/gcc cout.c
cout.c:1:22: iostream.h: No such file or directory
cout.c: In function `main':
cout.c:3: error: `cout' undeclared (first use in this function)
cout.c:3: error: (Each undeclared identifier is reported only once
cout.c:3: error: for each function it appears in.)
cout.c:2: warning: return type of 'main' is not `int'

You can take gcc package from
http://hpux.cs.utah.edu/
or
http://mirrors.develooper.com/hpux/downloads.html.

If gcc can't find iostream.h that means that it is installed incorrectly. The best way is to compile sources from www.gnu.org and then install them.

You are trying to use an obsolete or bundled C compiler on IPF to compile C++ source.

>gcc compiler couldn't find .h files

The Standard name is <iostream> and not <iostream.h>. For aCC, you need -AA to compile with the Standard. -AP (the default on PA) only takes the <iostream.h> name.

With respect to the GNU compilers, gcc is a C compiler, you should use g++ to compile and link C++ code, not gcc.

Hi Steve!

Where can I download g++ ?

You can download a trial version of the C/aC++ compilers from:
