Xcode 5.1 build opencv在64位模拟器上失败

Question

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

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

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)
Undefined symbols for architecture x86_64:

Answer 1

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

目标 - >构建设置 - >体系结构.双击架构

,选择其他,删除除了

$(ARCH_STANDARD)(' - ')

,然后增加

armv7和armv7s'+'

(点).再次编译清洁.
