    Question Missing <mem.h>?

    Hello I just got this book about ray tracing in C++ and I'm looking through the examples. Many of the examples include a file called <mem.h>. It seems to be a standard header file but I don't have it. Why don't I have it? More importantly, is there anyplace I can get it? Is it not a standard header file?

    try <memory> instead of <mem.h> and see if you have any luck, and if not, what compiler are you using?

    I changed it but now it's complaining about <values.h> ....I've never even heard of that file, any suggestions? It appears to be a non-programmer defined header file...

    Nope, sry. Are you trying to include <values.h> yourself or is it giving you an error about it when you try to include <memory>?

    Are they enclosed in <> or ""?

    well, if the header file is in the working directory of your compiler, then you use quotes. If the header is in your compiler's include directory or any other specially specified path, use the < > brackets.

    I think its good you said that, in case he didn't know that... I wasn't clear.

    If the original file had "s, then you have to make sure its in the same directory... if it was in <s, then I can't help you because I've never heard of that header.

    It's in "<>", that's why I put them in when I mentioned them. It turns out values.h isn't used anymore, it's obsolete. But values.h really only contained constants and stuff that are now in the files <float.h> and <limits.h>. The bad thing now is I don't what names to change things to to get everything to work. Looks like this might take awhile

    Question

    Would anybody happen to have an old <values.h> file lying around? That would be a tremendous help

    In general, you can't use a header file from a different compiler. See the Programming FAQ

    You have a few options:

    1- Get a book that is ISO/ANSI compliant (or that is compatable with your compiler.)
    2- Ignore the examples with non-standard headers.
    3- Search your compiler for similar functions that might be in a different header file.
    4- Write your own functions to replace the ones from the missing header file.
