Package: gcc
Version: 4.0.3-4
When the standard "hello,world" program is compiled in C++, the compiler cannot find the iostream header file because it's looking in the wrong directories. These directories seem to be hard-coded, and are so deeply nested that KNOPPIX5.0.1CD shortens the path name in the center. Here is an example of the output:
knoppix@1[~]$ gcc -v test.cpp -o test

Only the final two lines are visible without the -v option for gcc.
The offending program:
#include iostream
int main(void)
{
cout << "Hello, world!" << endl;
}
The classic beginner program shouldn't fail!
Thanks for your help,

iostream declares cout and endl in the namespace std. So either use
std::cout or add a using namespace std somewhere at the top.

Kill the writer. This source was never valid with any C++ standard.
