header file problem
Ok, I'm a bit embarassed to even ask this, but here goes:
I have a program with one main.cpp file, and a class contained in Foo.h and Foo.cpp. Foo.h contains the declaration of the class. Foo.cpp contains #include "Foo.h", and the implementation of the functions in that class. However, when I #include "Foo.h" in the main.cpp file, the compiler can't find the implementation of the functions. However, this approach works fine whenever I do it in my IDE(XCode), it's only when I use notepad and terminal that this problem arises.
I've been wondering for some time how the compiler knows which .cpp-file accompanies a .h-file, so if someone out there could bear with me and explain to me what I'm doing wrong, it would be greatly appreciated;)

Have you tried using something that doesn't suck ass like notepad?
I suggest Notepad++. It's probably a better way to go.

If you are compiling on the command line are you including all of the .cpp files in the command?
g++ main.cpp Foo.cpp
g++ main.cpp Foo.cpp
GCC is slippery for multi-file processing at best.
EDIT: what darkestfright said should work.

P.S.- Isn't Mac one of the most terrible platforms to develop for if you're using C++? :P

darkestfright: that sovled it, thanks;) still new to c++;)
Albatross: I haven't found anything to be wrong with it yet, how come?

No. Windows is definitely the worst platform I've ever developed on. MacOS directory structure is similar to Linux's which I think helps but the fact that it's a controlled and proprietary OS is another. It's probably a little bit more friendly than Linux some times.

First of all, what's the gripe about notepad? Source files are text files--that's it.
Second, why the GCC bashing?! GCC is one of the best compilers available. Also, darkestfright's command line will work...

@Computerquip: Okay. Good point, I has only developed on Mac and GNU/Linux with GTK+. I took a look at the documentation on Windows' API and... @_@
Though I did mean programming programs like smultron. I just can't stand Objective-C for some reason, and it's better to use than than C for the Cocoa APIs.
Also, I wasn't bashing GCC, and I don't think anyone here was. It's an excellent set of compilers, just not always straight forward and some have problems with that.
