Is there any way to use C++17 on MSBuild? #1662

Akarinnnnn · 2019-02-07T16:05:11Z

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\source\cpp-addon\svlaunchdll_jswrap.cc(135): error C7525: 内联变量至少需要 "/std:c++17" (编译源文件 ..\cpp-

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 · 2019-06-20T06:07:28Z

please try and use Refael's exact syntax:

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

note the placement of {' and ['s

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 · 2021-01-06T02:36:50Z

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)

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.

ToadKing · 2021-01-12T15:59:33Z

Ran into this issue myself. Setting it through "msbuild_settings" worked but I think doing it that way messes up the node.exe hooking stuff since the compiled module would not load in electron. It also changes some other flags as well since the module no longer built as a static binary.

@refack's original suggestion worked for me. That said, the "VCCLCompilerTool" option should probably be updated to allow setting "LanguageStandard" directly instead of adding it through an additional command line option.

julianmesa-gitkraken · 2022-10-06T15:08:12Z

         "msvs_settings": {
            "VCCLCompilerTool": {
              "AdditionalOptions": [
                "/std:c++17"

Add the following to your binding.gyp:

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

nice, it works!!

For those coming here trying to get C++ 20 working with node addons relying on either Node directly or a derivative (e.g. Electron), don't forget that on Windows you will need to specify /Zc:__cplusplus. It took a while for me to discover this sharp windows specific edge...

Psychlist1972 · 2024-09-06T19:04:44Z

In my case, the -std:c++17 didn't work with VS 2022 and MS Build. I had to use the CLCompile version mentioned above.

I was banging my head up against the wall trying to find out how to override the C++20 that node-gyp was putting into the vcxprj but never could locate the source.

This is all because NodeRT uses C++ CX to create the projections, and that is not compatible with C++ 20.

    "msbuild_settings":{
        "ClCompile":{
            "LanguageStandard": "stdcpp17",
            "AdditionalOptions": "/ZW",
            "AdditionalUsingDirectories": [
              "%ProgramFiles(x86)%/Microsoft Visual Studio 14.0/VC/lib/store/references",
              "%ProgramFiles%/Microsoft Visual Studio 14.0/VC/lib/store/references",
              "%ProgramFiles(x86)%/Windows Kits/10/UnionMetadata/10.0.20348.0",
              "$(VCToolsInstallDir)/lib/x86/store/references",
              "../../",
            ]

        }
    }

I still have this in the binding.gyp, but it is overridden by the msbuild settings above

    "msvs_settings": {
      "VCCLCompilerTool": {
        "AdditionalOptions": ["/ZW", "-std:c++17"],
        "DisableSpecificWarnings": [4609],
      }
    },

In my case, node-gyp was adding both that and the /std:c++20 to the project file by default, with no obvious way to override.
