XCode 4.6.3 compile fail

[sharrismobiquity]

When I include MSWeakTimer.m in my iPhone XCode project, I get the following errors at line 169 of MSWeakTimer.m ( __weak typeof(self) weakSelf = self; ) - A parameter list without types is only allowed in a function definition. A corresponding warning tells me that __weak only applies to Objective-C object or block pointer types; type here is 'int'. Any idea why I get these warnings/errors, and what I should do about them?

Thanks!

That doesn't make sense :-/ self is a pointer to MSWeakTimer. Do you get any other errors? Did you import the .h file too?

[sharrismobiquity]

Yes I imported the .h file as well... and these are the only errors I get in the whole (massive) project unfortunately...

[JaviSoto]

Can you post a screenshot of Xcode showing the error?

[sharrismobiquity]

I just posed an image showing the compile fail and warnings that I'm getting... thanks for your quick response!

[JaviSoto]

Did you modify the file in any way? Is your project / are you compiling that file with ARC?

[sharrismobiquity]

Hi! No I didn't modify it in any way - I recopied it into the project just to make sure of that. And as for ARC, I'm pretty sure we do that. I certainly didn't add any specific non-ARC flags for this file. What project settings do you think might be relevant? We are highly customized in our project settings...

[sharrismobiquity]

Do you want to see the Apple LLVM compiler 4.2 code generation and/or language options, etc?

[sharrismobiquity]

BTW I can build the included sample project just fine btw... which argues for some odd or unusual local compiler settings or somesuch...

[JaviSoto]

Yeah that makes sense, I'm going to try to figure out what it is. Just for the sake of testing, can you try changing:

__weak typeof(self) weakSelf = self;

to

__weak MSWeakTimer *weakSelf = self;

And tell me what the result is?

[JaviSoto]

Also, on the error list, there's one red circle that has a smaller white circle inside. This is the "fix-it" feature on Xcode. Can you click on it and tell me what the code looks like after the recommended fix?

[sharrismobiquity]

wooh - we liked that! That seems to compile fine... that is equivalent code, no? And would you think I'd be ok to use that change?

[JaviSoto]

Yeah, that would be equivalent, and I wouldn't mind changing my code to that tbh (typeof() is a little overused in these expressions anyway). I would like to get to the bottom of this if we can though.

[sharrismobiquity]

hmmm I will poke around and see if there is something that I can narrow it down to. But nothing obvious in build settings thus far...
