wdetest crashes on OSX lion #48

Closed tcolar closed 8 years ago

tcolar commented 8 years ago

Is it just too old ? The doc does not specify a minimum version as far as I can tell.

Thank you.

Huh, apparently yes. Looks like initWithNibData was only introduced in 10.8:

https://developer.apple.com/library/mac/documentation/Cocoa/Reference/ApplicationKit/Classes/NSNib_Class/#//apple_ref/occ/instm/NSNib/initWithNibData%3abundle%3a

Tbh I haven't quite figured out what all the nib business is about, but I'll try to figure out another way to skin this cat.

@tcolar Can you try the pull request and see if that branch runs on your machine? The oldest I have at my disposal is 10.9.

tcolar commented 8 years ago

Sorry had commented on wrong PR

So I tried this on Lion and it works great.

To be fair Lion is pretty old, it's just that the only mac I own currently can't run anything newer, so that's what I can test my stuff on, short of borrowing someone's newer mac.

So in any case if the NIB stuff is useful and needed, I would be OK with just a branch (or even fork) for this, whatever works best for you.

Thanks.
