Xamarin.ios Xamarin iOS在生成期间无法AOT程序集

在构建我正在迁移到统一Xamarin API的Xamarin iOS应用程序时，我在编译的AOT阶段看到一个构建错误。我看到的错误是“无法对程序集进行AOT”，后跟程序集名称。我正在为一个设备构建调试模式（尽管我目前只支持ARMv7架构）

未能进行AOT编译的程序集是我为本机第三方iOS库编写的绑定DLL（它是专有的，因此很遗憾，我无法共享它）。绑定项目DLL包含在一个库中，该库由nuget打包并安装在我的Xamarin iOS应用程序中

我搜索了这个错误，找到了一堆Xamarin论坛帖子和bugzilla条目，并尝试了建议的大多数步骤，包括：

• 已尝试链接所有程序集，但仅链接SDK程序集
• 尝试从本地fat二进制文件中删除模拟器架构以减小大小，二进制文件现在是5.3MB（基于Xamarin论坛的这篇文章）
• LLVM已禁用，但启用和生成会导致相同的错误
• 增量生成已被禁用
• 在Mac上的Xamarin Studio中构建，同样的结果

我已经用“-v-v-v-v”作为额外的mtouch参数运行了一个构建，正如在几个论坛帖子中建议的那样，并附上了构建日志。我还将Visual Studio和Xamarin Studio的系统信息附加到Mac上

构建日志显示：

SByte[]类型的结构字段不能作为LPArray封送

所讨论的程序集具有一个带有SByte[]字段且没有[MarshalAs]属性的结构（这意味着它将被封送为LPArray，这是默认设置）

AOT编译器不支持该场景，因此AOT编译失败

此问题必须由库供应商解决。

您提到您已尝试链接所有程序集和仅链接SDK程序集。-->您是否尝试了

不链接

选项。这个行吗？如果可行，请尝试将

--linkskip=MyCompany.Ingenicobbinding

添加到

iOS Build

下iOS项目选项中的

附加mtouch参数

字段中。我可以看到几个SByte[/code>类型的结构字段，但找不到[MarshallAs]属性，该属性位于绑定项目代码中的任何位置，或者在我使用Dotpeek检查输出DLL时使用。实际上，我认为LPArray是数组的默认封送处理。但问题仍然存在：AOT编译器不知道数组的大小，因此无法为其生成代码。我已经能够通过删除绑定项目中使用SByte[]字段的部分来解决这个问题。对于将来可能会发现此问题的任何人，是否可以将其替换为IntPtr字段和手动封送，或者这是本机库的一个实现细节？您几乎总是可以将自动绑定替换为IntPtr（或其他值类型，取决于本机定义）字段和手动封送。
