Question

我正在尝试绑定Objective-C库，并且我已经成功生成了二进制文件。但是，当使用Objective Sharpie时，我会得到一个似乎来自iOS SDK内部的错误列表。我启动以下命令：

sharpie bind --output RealtimeSharp --namespace Realtime --sdk iphoneos9.0 ./Realtime/OrtcClient.h

我得到以下输出：

Submitting usage data to Xamarin...
  Submitted - thank you for helping to improve Objective Sharpie!

Done. Exiting with error code 1.
error: Clang failed to parse input and exited with code 1

我的SDK列表（sharpie xcode -sdks）：

sdk: iphoneos9.0          arch: arm64   armv7
sdk: macosx10.11          arch: x86_64  i386
sdk: watchos2.0           arch: 
sdk: watchsimulator2.0    arch:

我的目标Sharpie版本是（sharpie --version）：

2.1.6p 6e2f8ea 6e2f8ea5ac2f544c58938555a06ef21a4ecb032a 2015-03-17 17:39:55

我的Xamarin Studio的版本是5.9.7（版本9）。

Answer 1

在-xobjective-c之后添加-c argument后，我可以成功生成绑定。有些事情喜欢：

sharpie bind -output Binding -sdk iphoneos9.2 -scope build/Headers build/Headers/Example/Example.h -c -xobjective-c -Ibuild/Headers -arch arm64

我的Sharpie版本是3.0.8。

Answer 2

Xamarin says这是一个客观Sharpie的错误，所以他们很快就会发布一个新版本。

目标Sharpie失败，错误源自SDK的头文件
