I just grabbed the latest 3.4.9 release to update my cocos2d project from an older 3.x version and everything worked great for iOS. I tried to build my project for Mac as well but am receiving build errors. Trying to build my project produces linker errors on cocos2d classes, however trying to build the libcocos2d-mac target directly also produces separate build errors related to the libcocos2d-mac target. The first build error is in CCDirector. I attached an image.
Any help would be appreciated.
