DOMHTMLInputElement is no longer implemented in WebCore; you may need Xcode 8.3 beta to use trunk WebKit with system applications.
So, how do I fix the build script and the simulator safari launch script so that it does not crash? Why is it still referencing this object if it is no longer part of webcore?
This depends on what you are trying to achieve. Let's continue the discussion internally. From WebKit point of view, this is expected behavior. It is unfortunate that it is no longer possible to run shipping MobileSafari with ToT WebKit, but this is not going to be fixed from WebKit side.
Hmm, I didn't know about WK_IOS_BINCOMPAT_LDFLAGS. Maybe this could be fixed from WebKit side, Dan would know better.
Yes, adding a definition of WK_IOS_BINCOMPAT_LDFLAGS_V10_2 (or whatever matches the iOS SDK being used) may work. This is just not something anyone working on WebKit has tried to accomplish.
I'm trying to compile webkit & run in the iOS simulator, but I'm seeing the same crash as described. Is this going to be fixed at some point, or could someone take on making some kind of host app that could run in the simulator?
