与metaio相关的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:
  "std::__throw_logic_error(char const*)", referenced from:
      tesseract::WordListLangModel::AddString32(int const*) in metaioSDK(word_list_lang_model.o)

      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，我将其减少为6个错误

Answer 1

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

此link也可以为您提供帮助。

新更新：

检查完代码后，我在您的项目中发现了一些问题，您错过了StoreKit and StoreKitUI and MeidaPlayer框架。

您的部分构建设置配置不正确。请使用此图片中显示的确切配置。 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。

Answer 2

EKEventEditViewController表示您没有链接到EventKitUI.framework。

SLComposeViewController表示您没有链接到Social.framework

Answer 3

我通过更新sdk解决了所有错误，我遇到了很多问题（这里：http://helpdesk.metaio.com/questions/38835/ios81-unity-455-metaio-60-sdk-mach-o-linker-errors-in-xcode-61）

Answer 4

使用以下配置绑定它：

<强>框架：

添加链接器标记：

将ViewController扩展名更改为.mm：

内部构建设置将语言C ++设置如下：

并设置C语言方言：

同时

检查所有框架是否正确链接

检查您需要的所有文件是否已注册到＆＃34;构建阶段＆gt;编译来源＆＃34;

在iOS 8上测试
