These are WebGL 2.0-specific concepts and including their headers in the base class's header seems conceptually wrong. Can you find another solution?

Hmm, WebGLAny includes the WebGL 2.0-specific types. I don't know how it can do that.

Thanks for the fix!
The includes should go to webglany.h .. I can try to remember to fix it after implementing nonunified builds for Mac

That's my first attempt (attachment#423086 [details]), but it turned out it involves a XCode problem.
https://ews-build.webkit.org/#/builders/55/builds/4143
If you create a patch for Mac port, I'd be glad to test it for WinCairo port Non-Unified builds.

I think that means WebGLAny is a "private framework public header", and if it includes something, that something must also be "private framework public header".
E.g. you'd need to include with <WebGLSampler.h> and then mark WebGLSampler.h framework private, too. Which is tricky to say the least without Xcode.

Sure, I'll try.

I suggest using forward declarations in the WebGLRenderingContextBase header and only including the needed headers in .cpp files.

I think the error says that it already sees the forward declaration.

This is the case where WebGLAny uses things by value, but does not include the headers. Thus all clients of WebGLAny must include the headers -- which is impossible, as they should not be able to define how WebGLAny is implemented.

Same as:

class WebGLAny {
public:
 String value;
};

So in this case, the WebGLAny should #include <wtf/String.h>, as the other option does not make sense.

OK, thanks for the background - still, I'd suggest encapsulating the header inclusion as best as possible, for example by adding the #includes only to WebGLAny.h.
