Question

我已按照https://university.xamarin.com/lightninglectures/ios-bindings-in-cc中的所有步骤在Xamarin iOS应用中映射C库。但是当我尝试构建xamarin IOS应用程序时，它会给出以下错误。

Answer 1

某些选项（如-force_load）不是mtouch的选项，而是本机链接器的选项。

它们应该在mtouch参数下的-gcc_flags之间引用。

您可能没有正确地将它们（错误的顺序或没有引号）添加到项目选项中的其他mtouch参数。

Answer 2

由于mtouch参数中的命令复制粘贴，错误即将发生 ie -gcc_flags＆＃34; -L $ {ProjectDir} -lexample -force_load $ {ProjectDir} /libexample.a

在mtouch参数中手动更改双引号后问题得到解决。
