title: Objective C: Inline function - symbol not found
body: <p>I have a library which uses an inline C function,
  and is compiling just fine.
  When another library references that library, it still compiles fine.
  But if an actual app references the library, it fails to compile, saying that the _functionNameHere (yes, function name beginning with underline) - symbol is not found.</p>
  
  <p>If I remove the inline specifier, it all compiles fine. But as long as a function is inline inside the library, the app can't compile!</p>
  
  <p>Any ideas as to why that is?</p>
  
  <p>I know pretty much about compilers, but am new to the Objective-C, and anything I know about it is nothing more than educated guesses. And even that way I can't think of a reason that it will behave that way.</p>
  
  <p>The thing is, the inline function is INLINE, which means there's no symbol at all, it is compiled inline wherever it is called, and the referencing app should not even know it ever existed.
  That's true as long as the inline function is always inline-able, and is private to the library, and there's no special compiler configuration which prevents inlining, and all of those are true.</p>
  
  <p>So, anyone please come and point the finger at what I'm doing/thinking wrong...</p>
  
  <p>Thanks :-)</p>
