Question

我正在尝试在Xamarin中使用Good Dynamics SDK，我不太了解Objective-C，所以我在这里有点迷失。这是一个概念证明的尝试，我不确定这是否真的可行。

我已将GD文件从GD.framework目录添加为GD.a，并尝试实现API绑定并从示例XCode项目复制应用程序启动逻辑。

即使Mono Develop以红色显示ApiDefinition中的所有内容，我仍然设法构建它。

构建时，这是错误日志Full version here

这种情况持续了很长时间，并以错误

结束

error MT5202: Native linking failed. Please review the build log.

现在我有点卡住了。有什么想法吗？

Answer 1

ld消息告诉您，.a静态库文件不包含i386的代码。需要该架构才能在iOS模拟器上运行代码。

也许GD包为不同的体系结构提供了不同的.a。在这种情况下，您可以使用lipo工具构建一个包含多种体系结构的 fat </ strong>库。

Answer 2

我需要在iPhone构建选项中的“附加mtouch参数”中添加-cxx。

Answer 3

这是一个老问题但是，经过几个小时后，我们有完整的解决方案，可以在这里详细编写使用Good Dynamics和Xamarin.iOS ...需要5种不同的解决方法。
