Have you tried GCC? i.e.
g++ nameofprogram.cp -o anyname
Hi!
Using KNOPPIX 5.0.1CD, the gcc compiler for C has no trouble finding stdio.h. The C++ compiler cannot find iostream.
1. Do you have any suggestions for a work-around?
2. I'm going to be remastering this version of KNOPPIX to have some tools that aren't in the standard version, so I could change path variables, etc. What needs to be changed?
Thanks,
Fred

Thanks, WaKa!
What I did was the simple "hello, world!" program in C and C++, using exactly the format you suggested.
For C, it worked absolutely as expected, so I was surprised when it couldn't find iostream for the C++ version of the program (using cout << "Hello, world!" << endl; ), and I got the error message that ostream was not defined in this function! I gave it this:
#include <iostream>
for C++, just like I gave it:
#include <stdio.h>
for the C case. I tried the alias for gcc (g++), as well. If I specifically gave the absolute path to iostream it worked.
Since this is a Live CD, however, I'd have to re-master to add a PATH or an alias.
So suggestions are still welcome!

use this:
#include <iostream>
int main()
{
std::cout << "Hello, world!" << std::endl;
return 0;
}
Thanks for your reply, WaKa.
The problem is that gcc can't find the #include file iostream, not that it's using the wrong namespace.
Whe I use the -v (verbose) output, it tells met that it is, in fact, looking in a non-existent directory. - many directories deeper than the real one.
Does the program you gave actually work on your copy of KNOPPIX 5.0.1CD? If so, then I'll have to try another download.
Thanks,
Fred

As I read this, gcc is looking in a bunch of wrong directories for the C++ include files.

Post your source code. I think it is that you are not using the STD namespace.
You should do this in your file:
#include <iostream>
using namespace std;
int main (void)
{
cout << "Hello World!" << endl;
return 0;
}
See if that works. If that doesn't work, post your source.
gcc is the compiler for CCode:knoppix@1[~]$ gcc -v test.cpp -o test
g++ is the compiler for C++
test(name of program) is not a unique name because it conflicts with bash.
use this
g++ -v test.cpp -o test_1 (or what ever you like)
