    Too Much Global Data!!!!

    Ok, I've been working on this RPG for a long time now, and I keep getting the error, 'Too much global data', no matter what I do. I've tried several things to limit my data. For each screen in the game, I have a matrix with integers standing for different terrain, and I used to have a huge three-dimensional array with all this data. Now, however, I have made a screen class and made each screen an instance of that class. It still tells me I have too much global data, even though I have none! Could anyone tell me different criteria that could cause this error?

    You should probably put your terrain maps into files and load them when the program starts or as needed.

    As for addressing the error directly, it's probably something to do with how you load the data into your screen class instances.
    It is too clear and so it is hard to see.
    A dunce once searched for fire with a lighted lantern.
    Had he known what fire was,
    He could have cooked his rice much sooner.

    Lemme guess, you're using Turbo C, or some other ancient fossil compiler right?
    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.

    Yep, even older. Borland C++ 5.02. It's what I have right now and I don't got loads of money to buy a new one, they're expensive.

    I have already tried the file option. The point is that the data is stored in a class and other functions. It is not global, so what could cause the compiler to think it is global?

    The MinGW port of g++ is available at zero price and works with a number of free IDEs including Code Blocks, Dev-C++, and Netbeans.

    Alternatively, Microsoft Visual C++ 2005 and 2008 IDEs can be downloaded and used for free as Express versions, without restriction on the licensing of programs that you develop with them.

"Finding the smallest program that demonstrates the error" is a powerful debugging tool.

    It could be static, or initialisation data as well. It doesn't make a difference to the real low level stuff. It all takes up space, and due to your compiler, you're stuck with those tiny 64K limits.

    Now there are ways around this, but it's rather like rearranging the deck chairs on the Titanic.

    As for compilers, the world is awash with good quality free compilers, which are perfectly adequate for all student/hobby needs.

    You only really need spend $ when you're going to be getting $ in return for your efforts. Even then, it's not compulsory.
