什么是正确的macOS vscode intellisense C ++包含标准库的路径？

Question

我在macOS Sierra上使用Visual Studio Code 1.14.2并安装了Microsoft C / C ++ ms-vscode.cpptools扩展，但是在设置包含路径以使IntelliSense正确检查标准库头时没有产生错误，回到'Tag Parser'机制。

对于此vscode版本，缺省c_cpp_properties.json包含以下内容：

{
  "configurations": [
    {
      "name": "Mac",
      "includePath": [
        "/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/include/c++/v1",
        "/usr/local/include",
        "/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/lib/clang/8.1.0/include",
        "/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/include",
        "/usr/include",
        "${workspaceRoot}"
      ],
      "defines": [],
      "intelliSenseMode": "clang-x64",
      "browse": {
        "path": [
          "/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/include/c++/v1",
          "/usr/local/include",
          "/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/lib/clang/8.1.0/include",
          "/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/include",
          "/usr/include",
          "${workspaceRoot}"
        ],
        "limitSymbolsToIncludedHeaders": true,
        "databaseFilename": ""
      }
    },
...
}

例如，使用简单的C ++文件，例如：

#include <exception>

int main() {
    return 0;
}

#include <exception>带有下划线。 悬停在它上面说：

file：'file：///path/to/vscode.cc'严重性：'信息'消息：'＃include错误检测到。 请更新您的includePath。 Tag翻译器将提供此翻译单元的智能感知功能（/path/to/vscode.cc）。 at：'1,1'来源：''

和

file：'file：///path/to/vscode.cc'严重性：'Info'消息：'无法打开源文件“endian.h”（依赖于“exception”）'at：'1,1'source： “”

我搜索了我的文件系统endian.h 。 调整看起来与主机开发实际相关的可能性（即放弃iOS / WatchOS /等）：

/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/System/Library/Frameworks/Kernel.framework/Versions/A/Headers/i386/endian.h
/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/System/Library/Frameworks/Kernel.framework/Versions/A/Headers/machine/endian.h
/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/usr/include/i386/endian.h
/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/usr/include/machine/endian.h
/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/System/Library/Frameworks/Kernel.framework/Versions/A/Headers/i386/endian.h
/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/System/Library/Frameworks/Kernel.framework/Versions/A/Headers/machine/endian.h
/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/include/i386/endian.h
/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/include/machine/endian.h
/System/Library/Frameworks/Kernel.framework/Versions/A/Headers/i386/endian.h
/System/Library/Frameworks/Kernel.framework/Versions/A/Headers/machine/endian.h
/usr/include/i386/endian.h
/usr/include/machine/endian.h

有谁知道这个问题的正确解决方案是什么？

Answer 1

这竟然是IntelliSense引擎中的配置错误。 Mac标头需要定义符号__LITTLE_ENDIAN__ ，而不是。 我们已在最新的扩展更新中更正了此问题，因此无需再添加到endian.h的路径。
