Question

我们正在创建一个应用程序，我们使用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Project的“Build Setting”中的“Valid Architecture”从“armv7”更改为“armv7s”和“arm64”，它会给我们大约50个编译时错误。下面是编译时得到的错误。我们只是想知道，如何使用“arm64”和“armv7s”成功编译应用程序。您能告诉我们在App的项目“构建设置”中需要进行哪些配置更改才能运行项目吗？如果您需要我们关于项目的“构建设置”设置的任何进一步帮助，请告诉我们。

另外，我们在您的网站上看到您支持arm64 / x86_64（iPhone 5S +，iPad Air +，iPad mini retina +，模拟器）。所以，我们只是想知道你是否支持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： Architechures：标准建筑（armv7，arm64）基础SDK：最新的iOS（iOS 8.3）仅构建活动架构：否有效的建筑：arm64，armv7，armv7s

iOS部署目标：iOS7.0

其他链接器标志：-lxml2

我通过更改构建设置中的以下内容来解决问题：

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)

Luxand SDK无法在iPhone5C中安装
