我将企业库绑定到我的 Monotouch 应用程序。自从 Objective Sharpie 未能创建 API 以来，这是一个艰巨的过程，我不得不发挥创造力。
但是现在，在编译终于成功后，我面临着一个链接问题

      ...

等等。我尝试按照在 Objective-C 中包装 C++ 库中的建议没有隐藏 C++ 符号，但它没有用。任何想法？

您好，您似乎正在使用非 C++ 编译器进行编译，您可能想尝试在您的iOS 项目选项中设置它，或者在LinkWith attribute您应该IsCxx = true在iOS 绑定项目中设置

iOS 项目构建选项的可用选项是

  • --编译器：gcc
  • --编译器：g++
  • --编译器：clang
  • --编译器：clang++

你应该尝试--compiler:g++或者--compiler:clang++

希望这可以帮助

所以最终解决问题的是使用链接标准 C++ 库

LinkerFlags="-lsqlite3.0 -lc++"

我的整个 LinkWith 属性如下所示：

[程序集：LinkWith ("libMyLibrary.a", LinkTarget = LinkTarget.ArmV6 | LinkTarget.ArmV7 | LinkTarget.Simulator, SmartLink = true, ForceLoad = true, IsCxx = true, Frameworks = "SystemConfiguration CoreLocation CoreTelephony MobileCoreServices MessageUI", LinkerFlags=" -lsqlite3.0 -lc++")]
