MinGW Installation

Im trying to install the MinGW compiler on my Windows XP Laptop, but i'm having a few difficulties.

I had no problems with the installation itself, and the PATH settings went smooth, but i've hit a brick wall now.

I'm trying to compile a Hello World app:

Code:

---

#include <iostream>

int main()
{
        std::cout << "Hello World!";
        std::cin.ignore();
}

---

But im getting a long list of errors:

Code:

---

hello.cpp:7:2: warning: no newline at end of file

Looks a bit like linking errors, but i'm not sure, how do i fix this?

You included C++ in the installation, and ran something like this:
g++ -o hello.exe hello.cpp
right?

Ehh, no, that's not quite what i did. I did include C++, but i just did "gcc hello.cpp". Anyways, it's working beatifully now. What is that "-o" parameter for? Just the output name of the program?

Is there a way to make MinGW compile the program and then run it for me, so i don't have to do it manually?

Yes, you can do a g++ --help for more options.

I do not think so, though it should be possible to write say, a batch file (or a program, heheh) that could automate this. Personally, I do not see running the program yourself as being particularly difficult ;)

Yea, i was thinking of just doing a batch-file for it aswell, i'll get around to that later.

I've been using Dev-Cpp for the last couple of months, and it has that F9 shortcut for compiling and running your program, so after changing, having to do it all manually just seems like a daunting task :)

Anyways, thanks for the help Laserlight!
