今天我尝试在Xcode 5.1中编译我的示例应用程序并且我收到链接器错误，有人可以告诉我它为什么会发生？

4 个答案:

答案 0 :(得分：4)

cocos2d-x的最后一个版本（Cocos2d-x v3.0 rc0）解决了这个问题。新版本增加了对XCode 5.1的arm64支持。

您应升级项目，从here下载新版本。

更多信息可在官方changelog找到。

答案 1 :(得分：3)

转到项目设置，构建设置，体系结构，然后选择“其他......”。修改字符串以阅读$(ARCHS_STANDARD_32_BIT)。

答案 2 :(得分：0)

这些外部库是否也为arm64编译？因为如果没有，那么你必须在Xcode设置中禁用它，例如制作{ARCHS_STANDARD_32BIT}

答案 3 :(得分：-1)

更改您的库版本。

就我而言，我为iOS 7.1版本更改了UIKit.framework，CoreMotion.framework和OpenGLES.framework库。 （在构建阶段＆gt; LinkBinary与库）

删除红色图书库并添加新版本。
