Hi Arunprasad,

The last version of WebKitGTK to support Windows was 2.4, from 2014.

If you had 2.22 working, that's news to us. To my knowledge, nobody has 
ever done that before. You might well be the only one; certainly you're 
the only one to tell us about it. Anyway, that's cool.

We don't support Windows anymore because nobody seems to be interested 
in (a) making it work, and (b) maintaining the code upstream. So you're 
kinda on your own here. If you only needed a few downstream changes 
required to make it work, then we could consider accepting those 
upstream if you'd be willing to maintain the Windows-specific parts. 
We're not going to be willing to bring back real Windows support 
otherwise, since all current developers use Linux and are only 
interested in Linux.

Anyway, to answer your question: JavaScriptCore is used on Windows by 
the Apple Windows port and the WinCairo port, and there is very little 
GTK-specific code in JSC, so this should be the easiest part of 
WebKitGTK to get working on Windows. You might consider basing your 
Windows port on WinCairo rather than WebKitGTK, since that port is 
designed to run on Windows.

Good luck,
