Xcode Cocos2D - warning all apps should include an armv7 architecture

4
votes

My project started doing something odd. I can build and test OK, but when I archive I get:

Warning all apps should include an armv7 architecture

In Target build settings I have Architectures set as $(ARCHS_STANDARD) and Base SDK as Latest iOS with Valid Architectures set as arm64 armv7 armv7s

I googled this and found several solutions saying to go to Target>Build Settings>Build Active Architecture Only and set that to NO.

Doing that, the project will no longer build and I get:

CCDirectorIOS.h    Semantic issue   
Redefinition of '__ccContentScaleFactor' with a different type: 
'CGFloat' (aka double) vs 'float'

I'm quite a way through with this project and this is the first time I've had this problem. I've tried restoring from an earlier good backup and I get the same problem so presumably this has been caused by an Xcode update, and not by my own code.

Any suggestions?

Be sure to remove the arm64 slice if you're using v2.x of cocos2d-iphone as it is not compatible with 64bit builds. - LearnCocos2D
Thanks, a combination of that and changing the supported architecture to $(ARCHS_STANDARD_32_BIT) has solved the issue. - user3452012

Solution is simple, Change CGFloat to float

 extern float  __ccContentScaleFactor;
