尝试为Obj-C++头生成绑定，该头是使用rust bindgen的超级强大跨平台音频库的一部分

我在卡特琳娜10.15.6

clang version 10.0.1
Target: x86_64-apple-darwin19.6.0
Thread model: posix
InstalledDir: /usr/local/opt/llvm/bin

我被这个错误缠住了。搜索了很多，但似乎很少

我曾尝试使用Xcode应用程序包中提供的叮当声进行尝试，但无法做到这一点

这个库在Xcode中构建得很好，我在那里没有遇到同样的错误

/// @brief Output channel mapping for iOS audio I/O.
/// This structure maps the channels you provide in the audio processing callback to the appropriate output channels.
/// You can have multi-channel (more than a single stereo channel) output if a HDMI or USB audio device is connected. iOS does not provide multi-channel output for other audio devices, such as wireless audio accessories.
/// @em Example:
/// Let's say you have four output channels, and you'd like the first stereo pair on USB 3+4, and the other stereo pair on the iPad's headphone socket.
/// 1. Set deviceChannels[0] to 2, deviceChannels[1] to 3.
/// 2. Set USBChannels[2] to 0, USBChannels[3] to 1.
/// @em Explanation:
/// - Your four output channels are having the identifiers: 0, 1, 2, 3.
/// - Every iOS device has just one stereo built-in output. This is represented by deviceChannels, and (1.) sets your second stereo pair (2, 3) to these.
/// - You other stereo pair (0, 1) is mapped to USBChannels. USBChannels[2] represents the third USB channel.
/// @since Multi-channel output is available in iOS 6.0 and later.

/// @brief Input channel mapping for iOS audio I/O.
/// Similar to the output channels, you can map the input channels to channels in the audio processing callback. This feature works with USB only.
/// Let's say you set the channel count to 4, so RemoteIO provides 4 input channel buffers. Using this struct, you can map which USB input channel appears on the specific buffer positions.
