If I define a set of inlines within a specific class, they compile, but If I take the same functions and move them to a dedicated "inlines" file and include that, it doesn't. The compiler spits out the following:

Think about this for a second: "static" means file scope, so obviously you can't reference the symbol from another file. And non-static inlines can't actually be inlined because they may be called from elsewhere or have their addresses taken. So inline is useless to you. Just use an appropriate -O option that does whole-program transformation.

Here's the gcc manual on inline: http://gcc.gnu.org/onlinedocs/gcc/Inline.html

Also, this isn't a Cocoa question. You might want to pick up a book on C.
