How to enable RTTI on Windows?

C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\include\memory(883): warning C 4541: 'dynamic_cast' used on polymorphic type 'rocksdb::TableFactory' with /GR-; unpr edictable behavior may result (compiling source file ..\deps\rocksdb\tools\sst_dump_t ool.cc) [D:\home\js\modules_by_me\rocksdown\build\rocksdb.vcxproj]

I tried these, but it seems not work.

    'conditions': [
        ['OS=="win"', {
            'msvs_settings': {
                'VCCLCompilerTool': {
                    'RuntimeTypeInfo': 'true',
                    'EnableFunctionLevelLinking': 'true',
                    'ExceptionHandling': '2',
                    'DisableSpecificWarnings': [ '4355', '4530' ,'4267', '4244' ],
                }
            },
            'cflags!': [ '/GR-' ],
            'cflags+': [ '/GR+' ],

I’ve seen this issue and the fix appears to be set the value in both Debug and Release configurations. Otherwise it doesn’t properly override the default setting.

'conditions': [
  ['OS=="win"', {
    'configurations': {
      'Debug': {
        'msvs_settings': {
          'VCCLCompilerTool': {
            'RuntimeTypeInfo': 'true',
          },
        }
      }, # Debug
      'Release': {
          'VCCLCompilerTool': {
            'RuntimeTypeInfo': 'true',
          },
        },
      }, # Release
    }, # configurations
  } ], # OS=="win"
], # conditions

In my case, I don’t use node-gyp anymore, I compile the bindings directly with Visual Studio. But at the time I was using the following:

Electron: 5.0.6 node-gyp: 5.0.3 Visual Studio: VS2015 community node: 12.6.0
