Objective Sharpie 因 SDK 头文件中的错误而失败

Question

我正在尝试绑定一个 Objective-C 库，并且我已经成功生成了二进制文件。但是，在使用 Objective Sharpie 时，我得到了一个似乎源自 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 Objective Sharpie 版本是 (sharpie --version):

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

我的 Xamarin Studio 版本是 5.9.7 (build 9)。

Answer 1

Xamarin says这是 Objective Sharpie 的一个错误，所以他们很快就会发布一个新版本。

Answer 2

我在-c argument后面加上-xobjective-c就可以生成绑定成功了。像这样的东西：

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。
