Xcode 5.1 build opencv 在 64 位模拟器上失败 [英] Xcode 5.1 build opencv failed on 64 bit simulator

问题描述

我将 Xcode 更新到 5.1，并且在我使用 opencv 框架 2.4 的 iOS 应用程序项目中出现了许多错误.我的电脑是 macbook air 和 OSX 10.9.2.

I updated Xcode to 5.1 and many errors appeared in my iOS app project which use opencv framework 2.4. My computer is macbook air and OSX 10.9.2.

当我编译我的项目时，当我使用 Iphone Retina (3.5-Inch ,4-Inch) 模拟器时它工作正常.但是当我使用 Iphone Retina(4 英寸 64 位)时，当我尝试构建和运行时收到以下消息:

When I compile my project, it works fine when I'm using Iphone Retina (3.5-Inch ,4-Inch) Simulator. But when I'm using Iphone Retina (4-Inch 64-bit) I got the following message when I try to build and run :

ld: warning: ignoring file /Users/mike/Documents/opencv2.framework/opencv2, missing required architecture x86_64 in file /Users/mike/Documents/opencv2.framework/opencv2 (3 slices)

推荐答案

Xcode 升级到 5.1，苹果默认让所有 app 通过 64 位编译器.通过这种方式可以关闭:选中

Xcode upgrade to 5.1, apple default let all app through the 64 - bit compiler. By this way can close: selected the

目标 -> 构建设置 -> 架构.双击架构

Targets - > Build Settings - > Architectures. Double-click the Architectures

，选择other，删除除了

$(ARCH_STANDARD) (' - ')

$(ARCH_STANDARD) (' - ')

，然后增加

armv7 和 armv7s'+'

armv7 and armv7s' + '

(点).再次编译clean.
