How to enable RTTI on Windows?

[strrchr]

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+' ],

'RuntimeTypeInfo': 'true' is the right switch. Not sure why it isn't working for you.

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

Looks like this is resolved. I'll close.

], # conditions

This has been the solution in my case. Thanks!

I still fail on Release build...
Excuse me, may I know your version?
Mine:
Electron: 5.0.13
gode-gyp: 7.1.1
Visual Studio: VS2017 community
node: 10.16.0
bindings: 1.5.0

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
