    File sizes

    In DEV-C++, when I compile a simple hello world program, I've noticed, the size of the .exe compiled in DEV-C++ compared to the same code compiled in VC++ 9 Express is very different.

    Code:
    Code:
    #include <iostream>
    using namespace std;
    int main ()
    {
      cout << "Hello World!" << endl;
      cout << "Press ENTER to continue..." << endl; 
      cin.get();
      return 0;
    }
    EXE Compiled in DEV-C++ - 463 kb
    EXE Compiled in VC++ 9 XPress - 39 kb

    What?

    --------------------------------------------------------------------------------------------

    Also, can anyone tell me how to add an icon and file tags (Like description, copyright, ect.) in VC++ like you could in Dev-C++ through project options?

    Thanks everyone.

    Debug vs. Release will change the comparative sizes.
    Storing debug in the exe as opposed to storing debug in project files will change the comparative sizes.
    Static or dynamic linking with the run-time libraries will change the comparative sizes.
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.

    Ok, thanks but that still doesn't make alot of sense to me.
    --------------------------------------------------------------------------------------
    Can anyone answer my second question?

    You may discover that VC++ exes may not start on other computers if they don't have the necessary support files that you get with VC++. You'd need to distribute those too (once the user has those, you probably won't need to redistribute them with the next program).

    MingW exe's don't rely on external files (unless your program does). You can just copy the exe to another machine and it would work there.

    For distributing I tend to compile with MingW (I don't really want to put other stuff into other people's computers).

    (To make MingW exes smaller, you can use the strip option and make sure that the exe doesn't contain debugging info.)

    I might be wrong.

    Thank you, anon. You sure know how to recognize different types of trees from quite a long way away.

    I really didn't have time to do that tutorial today guys... But I will put one up. This computer doesn't even have VC++ on it to give a quick idea. But you can manually configure your compiler commands. All you need to do is put the gcc commands. I am on the same boat as anon. All commercial PC software I've sold independent of some firm has had its final compile done with gcc since it doesn't require extras and its licensing is not dubious at all.

    Anyway, enough bs. Here is why I posted.

    enjoy.

    I don't really want to make it a whole bunch of files, I think i'll just look for another compiler with gcc/mingW.

    Eh, the MinGW port of g++ is a compiler. If you are looking for an IDE to use the MinGW port of g++ with, then I would suggest Code::Blocks.

    MingW exe's don't rely on external files (unless your program does). You can just copy the exe to another machine and it would work there.
    Note that while it doesn't require "extras," the file size increases. You could call it bloat if you want. All the data is stored inside the exe, so every exe will be big.
    On the other hand,

    Visual C++ doesn't put data into the exe, unless you use static linking. This has the advantage that the exes becomes smaller.
    But the target machine needs the runtime installed. But again, it only needs to be installed ONCE, and then it will always work, whatever program it is you install.

    Which makes this approach stupid IMHO.
    But that's just my take. Different people use different approaches and there's no right or wrong.

    Wait so If I use static linking, my application won't require installation?

    No runtime files will be needed (but any external component such as controls that your app relies on will still need to be on the target machine), but the filesize WILL go up. And it WILL increase for EVERY application/program you make.
    I find it better to redistribute runtime instead since you will gain a lot of size in the long run.

    EDIT:
    Never mind, but I still would rather compile a stand alone app, as it's only an emulation of CMD with added commands... I don't think it's going to be very big.
    SO can anyone educate me on my error?

    You are probably not linking with your import library (xxx.lib, which corresponds to xxx.dll).

    Btw, your indentation needs work.
    In Visual Studio, you can do... select all text, press Alt+F8. Boom! Indented!

    The functions are located in user32.dll, so you should link against user32.lib. In Visual Studio, though, this should be automatic. For other compilers/IDEs, I don't know.
