"Qt requires C++11" error when building on macOS 10.13.5, Xcode 9.4.1, Qt 5.11.1

[ftab]

Here's my wd.gypi:

{
  'variables': {
    'QT5': '1',
    'WD_CONFIG_QWIDGET_BASE': '1',
# If Qt >= 5.6 set 'WD_CONFIG_WEBKIT' : '0'
    'WD_CONFIG_WEBKIT': '0',

    'QT_LIB_PATH': '/Users/fury/Qt/5.11.1/clang_64/lib'
  },
}

Made the following change to get it to kick off the build (I don't have the 10.8 SDK installed)

When I build, it runs into a problem with WebDriver_extension_qt_base:

I can see that there is -std=gnu++11 in wd_build_options.gypi but I don't see a gnu++11 or c++11 flag getting set anywhere in the resulting clang compiler command

How would I go about making sure this flag gets set? Or is that not the real problem?

@ftab I was able to fix this issue by adding:

'OTHER_CPLUSPLUSFLAGS' : ['-std=gnu++11'],

under osx xcode settings in the wd_build_options.gypi file.

Hope it helps.
