ios - metaio 的 mach-o 链接器错误

Question

我正在使用 Metaio SDK 和云插件，我无法通过 xcode 5 中的大量 mach-o 链接器错误。这里有一些，但我有 118 个:

Undefined symbols for architecture armv7s:

      tesseract::HybridNeuralNetCharKSBmHGiVwS::LoadFoldingSets(std::string const&, std::string const&, tesseract::LangModel*) in metaioSDK(hybrid_neural_net_classifier.o)

将部署目标设置为 6.0 后，我将其减少到 6 个错误

您为 iOS 6 显示的错误意味着缺少某些框架，请添加图像中显示的所有这些框架以使其适用于 iOS 6。



这个link也可以帮助你。

新更新:

检查您的代码后，我发现您的项目中存在一些问题，您缺少 StoreKit and StoreKitUI and MeidaPlayer构架。

并且您的某些build设置配置不正确。请使用此图像中显示的确切配置。 Other Linker flag必须是这样的:



和 C Language dialect必须是这样的:


并且此配置与此图像完全相同:


我已经使用所有这些配置测试了您的应用程序，现在该应用程序在 iOS7 和 iOS 6 上运行良好。
