Bug 197668 – Add option to build-webkit to control whether or not XCBuild is used

• Status: RESOLVED
• Resolution: FIXED
• Component: Tools / Tests

[Keith Rollin]

Add --[no-]xcbuild to build-webkit to force the use of XCBuild or not. Also update build-webkit and the makefiles with the foundation for automatically using XCBuild when the conditions allow it. This latter facility is currently turned off until Xcode fully supports building WebKit with XCBuild.

undef is also an option

😲

Thanks. My perl is a bit rusty and I'd forgotten this. I actually did a web search for the idiomatic approach to tri-state variables, but didn't turn that one up.

I don't understand what you mean by that.

Nothing actionable, just pretend that's what my face looked like while reading.

This is the most duct tape line of code I've ever seen.
