help with g++

[spzentz]

Hi,
I have installed the package that includes g++. The compiler will compile c++ files but I cannot run the executable (in the terminal). It always says command not found.
Any help is apreciated.
Thanks

This is probably due to the directory not being in your path. When in the same directory as the executable, try prefixing the name with "./". (without the quotes) to refer to the cwd.

Did you remember to put ./ in front of the executable?

Example: This is hello.cpp:


#include <iostream>

using namespace std;

int main()
{
cout << "Hello, World!\n";
return 0;
}

Compile and run:


$ g++ hello.cpp -o hello
$ ./hello
Hello, World!
$

Yes, I didn't realise that I needed the ./ before the executable.
Thanks for all the help.
