use of undeclared identifier '_window'

[NoonePauseferg]

when I try to make pangolin, I get this error: pangolin/src/display/device/PangolinNSGLView.mm:75:54: error: use of undeclared identifier '_window'

this part of code: -(void)reshape 1 { 74 #if MAC_OS_X_VERSION_MAX_ALLOWED >= MAC_OS_X_VERSION_10_7 1 if ( [self wantsBestResolutionOpenGLSurface] && [_window respondsToSelector:@selector(backingScaleFactor) ] ) 2 backing_scale = [_window backingScaleFactor]; 3 else 4 #endif 5 backing_scale = 1.0; 6 7 pangolin::process::Resize(self.bounds.size.width backing_scale, self.bounds.size.height backing_scale); 8 9 [[self openGLContext] update]; 10 }

I try to just comment this stuff and all was cool, but when I run HellowPangolin.py, I get only red window

help plz, mb I need to rename this variable?
