I just downloaded and installed Code::Blocks onto my laptop, intending to finally get back into Allegro and C++ now that the semester is over. I made a short little Hello World program to test it:

#include <iostream>
int main()
{
    std::cout << "Text";
    return 0;
}

But when I try to compile it, it tells me that iostream doesn't exist! I've reinstalled Code::Blocks and tried installing Mingw separately, but I haven't been able to fix the problem.

^ Sounds like that to me too. I'd suggest looking at the path of the compiler in Code::Blocks, and if you still can't find it, run a search for iostream on your whole disk.

Does the atrocious mingw installer still make you check a box for libstdc++? Without that, you don't have iostream, etc.

I reinstalled mingw and checked all the options available, but it didn't fix the problem.

When you downloaded mingw separately did you include c++, you may have just downloaded C. I can't remember the install process so this could be me talking rubbish.

That did it.

You'd think that you could just make a quick test program without starting a whole new project...

My only concern now is getting Allegro installed with Code::blocks. I'm off to see the wiki, the wonderful wiki of Allegro!

Ok, I installed Allegro just like LennyLen said (extracted the binary into my Mingw directory). I went into the linker options on Code::Blocks and linked to the library (if I'm recalling correctly from way back when I used Dev-Cpp, I link to liballeg.a), but it says there is no such file as allegro.h, and that none of the functions have been defined.

Do I need to put the entire include folder from the Allegro directory into the Mingw directory, or just the allegro.h file?

One final question: is there somewhere I can put the allegro dll so that all the allegro programs on my computer can run? I compiled and ran a test program, and it shouted at me about not having the dll. I know I had it set up on my old computer, but I don't remember how.

Do what now?

Remember, besides sitting down and typing actual code, I don't know a whole lot about computers.

Huzzah! Success! Thanks all.

One absolute final question, for reals this time.

Where can I download the allegro docs? I remember having a really nice offline html copy of them, but it doesn't seem to have been included when I installed Allegro.

The only file under html in the docs directory it something called tmpfile.
