ok so my problem has to do with some redeclaration of the functions that I declared in the Record.h file, I just can't figure out where im going wrong with my compiler directives and including files. It may be something else but thats what I think it is. Any help would be awesome I have to turn this in by thursday, and i already know the rest of it works because it did in C and im just converting it to c++.

here are the files

thanks

you may need to encapsulate your Record.h file with a few preprocessor directives.

hmm, I just saw that you had done that in your llist.h file. I've always thought it to be cleaner to do it the way I said. That way you only have to do it once per header, not once per include. So try that and see if it helps.

the problem probably stems from your "#include database.cpp" line. You shouldn't really ever need to include a *.cpp file.

i found this to be pretty informative. He seems to be developing on a windows machine, but the methods are still sound.

AHHH now I get this for some reason.... and it makes little sense to me. I tried running the program in Xcode but it runs instead of giving me these errors and just sits there.

Try using g++ instead of gcc. On most systems, I don't think gcc links in the C++ libraries by default, where g++ does.

the only problem then is that it just sits there after I run the program

Define, "just sits there." After succesfully compiling your code, if there are no warnings or errors, you will be brought back to the prompt. You can then execute your program using ./prj2.

Or are you saying after you run ./prj2, it just sits there? If that's the case, it is probably something with your code, which I haven't looked at.

it just sits there when I run ./prj2

ok now the problem is that for some reason my start variable ends up getting set equal to something other than NULL somehwere in there so it gets into the look that will find the next variable thats equal to temp and never gets out. I used the xcode debugger to get to the point where for some reason the statement

if(temp != NULL)

isn't working because it shows that temp = 0x0 in hex which is null right?


whats more when i try and open the file, there shouldn't be one named addressbook.txt anywhere so why is it opening that file

Ok I got it figured out, and my program ran fine once I removed the semicolon that was next to the if statement that checked to see if the file was open.

thanks all

Heheh, those pesky misplaced semi-colons...
