[Webkit-unassigned] [Bug 161864] Building on Win 64 (Windows 10 64 bit)

--- Comment #3 from Tom Sisson <thomas.sisson.1 at gmail.com> ---
What are the right flags? I deleted the source tree, started from scratch, and ran vcvarsall.bat. What about "features.h not found?" Is that an unimportant error?

I ran vcvarsall.bat amd64, reran perl update-webkit, and got the same error. At worst, it should build the wrong architecture. I opted to download all SDKs when I install Visual Studio. I should theoretically be able to build for iOS if I want, but I'm starting to think that the perl script needs to be smart enough to know what architecture it is running on. Even if it's can't be sure of the exact architecture, it should know it's on Windows and default to Win32.

I also note when I search for MSVC_CXX_ARCHITECTURE_ID I find many issues mentioned about CMake having problems. I see no clear explanation or solution. Is STREQUAL a defined function or built into Perl?
I'm not trying to be a smarta**, but does anyone actually try to build on Windows anything not specifically built for Windows. I suppose I could just boot up Linux, install mingw and crossbuild (whatever the tool is created by Gimp developers). However, I would prefer to do it on Windows.
