    6 measly errors

    Hi all

    I have been using the tuts on NeHe, and when i compile my code, from tutorial lesson 07, i get 6 errors, can anyone help me?

    Here are the errors:

    Code:

            Message: 'This function or variable may be unsafe. Consider using fopen_s instead. To disable deprecation, use _CRT_SECURE_NO_DEPRECATE. See online help for details.'
    Code:

    Code:

    You have no main() function and the last two function blocks before what should be main() end with a semi-colon. You also have semi-colons after quite a few if() blocks. I suggest you to stop trying to learn OpenGL and go back to page 1 of any beginner C/C++ book. Sorry to be so mean, but those are truly beginner mistakes and OpenGL is *so* far ahead of you right now.

    First it was Win32, now OpenGL...We're not saying you can't handle these issues, but you need to crawl before you can run. Check out a good C++ book and then move on from there.

    	// Shutdown
    	KillGLWindow();									// Kill The Window

    Read the errors. Define the undefined.

    And don't expect anyone here to wade through 6 screens of code.

    As for the errors, don't make the mistake of really defining this stuff. You need to include the standard C header that contains these functions. (Not telling you which this is. Visual Studio's built-in help can do that.)

    Of course. Wording, the enemy of getting one's point across.

    Not in the load of code you posted here in this forum. Also not in your own code, or you wouldn't get these errors.

    Or did you mean to say that now that we've pointed it out, you included it, and now the code works?
