Compilation error in "Hello World" program.

[PG]

Hi gurus,

I have AIX visual age C++ compiler version 5.0.2.3. I have a simple
hello world program that gives compilation errors. Any help will be
appreciated. Thanks

If a compiler can't compile its own header files that would indicate to me
that it is wrongly installed. Obviously that is beyond the scope of this
group.

However you might like to try the following legal C++ program (yours was not
legal) to see if you get any further.

#include <iostream>

int main()
{
std::cout << "hello, world\n";
}

Note the name of the header file <iostream>, <iostream.h> is not a standard
C++ header file. Also note the use of std::cout rather than cout.

I don't think either of these corrections explain the error message above
however.

You don't need those.

Well no, but's it not incorrect to have them.

#include <iostream.h>

Unlike the above header.

A couple of things

1) do a 'which cc' and make sure you're pointing to /usr/vacpp/bin
and not /usr/vac/bin. If you're pointing to 'vac' then modify
your PATH to add /usr/vacpp/bin to the front of it.

2) use xlC instead of cc

3) Don't call the program 'test' ... there's a Unix command of the
same name and if you don't have '.' in your PATH, you're going
to be even more confused when you get it compiled =8-)

Cheers

ps...Notwithsta nding the other remarks re your header files, your
example compiles and links okay on my 5.1 box when I follow
the steps above

Are you sure 'cc' is a C++ compiler? On the AIX box I have access to
the C++ compiler is called xlC, and cc is a C compiler.

Good point, plus the fact that the V5 compiler is out of service,
and their install is woefully back-level (you can still get the
5.0.2.9 update from the service website).

cc merely invokes xlC with certain default options. xlC is the C
compiler you need vacpp or some such to do c++, no?

Well, on our machines, xlc invokes the C compiler with configured
options. xlC invokes the C++ compiler with configured options. I'm not
sure how 'cc' fits into this scheme, hence my question.

This seems to be a known issue, see APAR IY23677 (TEXT "LLABS"
