ios - iPhone5C 中未安装 Luxand SDK

Question

我们正在创建一个应用程序，在其中使用 Luxand 库进行人脸检测和识别。我们从您的“LiveRecognition”示例应用程序开始。我们发现，如果我们将项目“build设置”中的“有效架构”从“armv7”更改为“armv7s”和“arm64”，则会出现大约 50 个编译时错误。下面是我在编译时遇到的错误。我们只是想知道，如何使用“arm64”和“armv7s”成功编译应用程序。您能否告诉我们需要对应用程序的项目“build设置”进行哪些配置更改才能运行该项目？如果您需要我们提供有关项目的“build设置”设置的任何进一步帮助，请告诉我们。

此外，我们在您的网站中看到您支持arm64/x86_64(iPhone 5S+、iPad Air+、iPad mini retina+、模拟器)。所以，我们只是想知道您是否也支持 iPhone5c，因为我们在 iPhone5c 中遇到了这个问题。

我的项目的项目设置是:架构:标准架构(armv7、arm64)基础 SDK:最新 iOS (iOS 8.3)仅构建事件架构:否有效架构:arm64、armv7、armv7s

iOS部署目标:iOS7.0

我通过在build设置中更改以下内容解决了该问题:

Architectures : Standard Architechtures(armv7, arm64) 
Base SDK : Latest iOS (iOS 8.3) 
Build Active Architecture Only: NO
Valid Architechture: armv7, arm64
iOS Deployment Target: iOS7.0
C++ Language Dialect: GNU++11[-std=gnu++11]
C++ Standard Library: libstdc++ (GNU C++ standard library)
