trouble with g++
 

I'm just starting to learn c++ and wrote a simple hello world program but when I try to compile, it outputs this:

<command line>: warning: "cpu" re-asserted
<command line>: warning: "machine" re-asserted
first.cpp:3:22: iostream.h: No such file or directory

I have no idea what this means, nor can I find any useful documentation on it anywhere on the web.
Does anyone know what's going on here? I desperately need to get my c++ compiler working...

no idea what the first bit means, but on my md81 distro iostream.h isn't on the default include path, which is a bugger. try using a printf statement rather than a cout / cin thing (assuming you are) to compile, if that works, then it's just the include paths to worry about

<command line>: warning: "cpu" re-asserted ??
 

Can anyone make any sense of this and glean any clues as to why I can't compile any c++ programs?

i can't make sense of almost all of the error messages... in fact i only understand one ;)
perhaps the most crucial one (unless a gcc/g++ guru deigns to come down from his ivory tower and explain to you otherwise) is the last line of your post...

as acid kewpie guessed rightly, your iostream.h file is not present in your include directory on your installation...

so... it's time to either upgrade your rh6.0 to something more recent (since the later versions of the rh distro has more recent versions of gcc/g++) or go download latest gcc/g++ compiler and install it on your box... :)

or you could try doing this: :smash:

:) good luck!
