Node-gyp: Is there any way to use C++17 on MSBuild?

[Akarinnnnn]

• Node Version:10.15.0
• Platform:Windows 10 x64
• Compiler:MSBuild ,toolset v150
• Module:my SVLauncherDLL

Verbose output (from npm or node-gyp):

e:\visual studio项目\dsted\sourcecpp-addon\svlaunchdll_jswrap.cc(135): error C7525: 内联变量至少需要 "/std:c++17" (编译源文件 ..cpp-
addon\svlaunchdll_jswrap.cc) [E:\Visual Studio项目\DSTed\Source\build\SVLaunchDLL.vcxproj]

I need C++17, seriously.

Add the following to your binding.gyp:

  'msvs_settings': {
    'VCCLCompilerTool': {
      'AdditionalOptions': [ '-std:c++17', ],
    },
  },

i had changed binding.gyp as you said, but it does not work

[rvagg]

please try and use Refael's exact syntax:

            'msvs-settings':
            {
                'VCCLCompilerTool':
                {
                    'AdditionalOptions':
                        [
                        '-std:c++17',
                        ]
                }
            }

note the placement of {' and ['s

@rvagg still not working

This is a full working example for anyone who also has this problem:

{
  "targets": [
    {
      "target_name": "proj",
      "sources": [ "src/proj.cc" ],
      "include_dirs": [
        "<!@(node -p \"require('node-addon-api').include\")"
      ],
      'defines': [ 'NAPI_DISABLE_CPP_EXCEPTIONS' ],
      "cflags": [ "-fno-exceptions" ],
      "cflags_cc": [ "-fno-exceptions", "-std=c++17" ],
      "conditions": [
        ['OS=="mac"', {
            "xcode_settings": {
              'GCC_ENABLE_CPP_EXCEPTIONS': 'YES',
              "CLANG_CXX_LIBRARY": "libc++",
              "CLANG_CXX_LANGUAGE_STANDARD":"c++17",
              'MACOSX_DEPLOYMENT_TARGET': '10.14'
            }
        }],
        ['OS=="win"', {
          "msvs_settings": {
            "VCCLCompilerTool": {
              "AdditionalOptions": [ "-std:c++17", ],
            },
          },
        }]
      ]
    }
  ]
}

The solutions above didn't work for me - the only way I could get it to work was using

"msbuild_settings": {
    "ClCompile": {
        "LanguageStandard": "stdcpp17"
    }
}

It thows off some warnings, but it configures the project as it should and compiles

Yes. ClCompile MSBuild item controls how compiler treats source file

That's strange. None of the given solutions sets the standard in the sln file for the analysis. But it works for the build.

see .vcxproj file?

[AtiqGauri]

If anyone need solution irrespective of node-gyp use can use cmake... You can do this using cmake-js node package.
It easily handle these kind of things. Here is a example for you: https://www.github.com/AtiqGauri/Patternscape/tree/master/Patternscape_Native_Addon%2FCMakeLists.txt

Node-gyp should be able to do this automatically, but it does not. CMake easily does it by using.

set(CMAKE_CXX_STANDARD 17)

If anyone need solution irrespective of node-gyp use can use cmake... You can do this using cmake-js node package.
It easily handle these kind of things. Here is a example for you:

Thanks! I need to transfer to cmake-js. Too many problems with node-gyp. It does not solve anything for me as I have to manually maintain compiler flags for all the platforms.
