fatal error: IOStream: No such file or directory
I know this is a topic well discussed, but I have looked through this and other forums, but others mistakenly use .h. I am running Ubuntu with G++ 4.5.2.
My code:
#include <iostream>
using namespace std;
int main()
{
cout << "Hello world." << endl;
return -1;
}
I compile with:
G++ HelloWorld.cpp
My error is:
HelloWorld.cpp:1:20: fatal error: IOStream: No such file or directory
compilation terminated.
I can compile fine with both geany and eclipse IDE, but I am practicing with programming with terminal. Since it compiles with the IDE, I am leaning toward g++ and libraries being installed correctly. I have the iostream file in /usr/include/c++/4.5/iostream directory.
I would appreciate any help because I have struggling with this for a couple of days now.

Hi scratch509 I gust go throughout the code and I want to explain something:
In the main function when u return it u return 0 which is an interger that means return nothing.
If u return -1 in any function that means that u are logically that thear is an error.
I hope that u understand .

You couldn't be anymore wrong. void means you return nothing. When he/she returns -1, he/she returns -1, not 0.

What if I had a method that returned -1 on a successful call? It may not be common to return -1 on a successful method call, but never assume such things; everybody's coding style is different.
Scratch, a glance at your code reveals no apparent errors. However, considering you're on Ubuntu, installation is different than Windows. It would be beneficial to post this question in the Unix/Linux section of this forum.

You might have a problem with case sensitivity.
The header is called iostream, not IOStream. Likewise, the compiler is called g++, not G++.

Thanks everyone for the replies. I figured out my issue here. I don't even want to admit it, but it does help if you compile the same file you are editing. I did take the uppercase and the -1 comment onboard though and will remember it.
I have a nearly similar issue on my MacOSX computer, but there it doesn't even compile with an IDE. That is my next thing to figure out.
You guys are awesome.
