Bug 171788 – REGRESSION: ImageDiff not building with make

• Component: Tools / Tests
• Status: RESOLVED FIXED

[Alexey Proskuryakov]

I built WebKit with make, and tried to run tests:

ap$ run-webkit-tests --no-build
Using port 'mac-sierra-wk2'
Test configuration: <sierra, x86_64, debug>
...

ImageDiff was not found at /Users/ap/Safari/OpenSource/WebKitBuild/Debug/ImageDiff
Build check failed

[Alexey Proskuryakov]

I get this message even when not passing --no-build, which is a separate issue, but may be easiest to address at the same time.

ImageDiff was not found at /Users/ap/Safari/OpenSource/WebKitBuild/Debug/ImageDiff

Is this an iOS Simulator build?  Or Mac?

It's definitely looking in the correct spot, it's just failing to actually build ImageDiff.

attachment 309375 [details] should do the trick.

Actually, no Apple platforms were building the correct ImageDiff through Make.

Please explain that this is fixing a separate issue that you found while looking into this.

I'm not sure if this is even a bug. In the past, we explicitly disabled LayoutTestRelay building with DO_NOT_BUILD_LAYOUT_TEST_RELAY variable (it's actually still in place in trunk). The rationale was that we wanted to maintain symmetry with production builds.

But then I'm not sure about how testers would work. Really confused about the overall plan.

It's probably best to file a new bug about this, as it really seems like a separate issue.

Here is what we used to have in LayoutTestRelay/Makefile, added in <https://trac.webkit.org/r192106>:

OVERRIDE_ARCHS = default
OVERRIDE_SDKROOT = default

I think the difference with LayoutTestRelay and ImageDiff is that every platform needs an ImageDiff, it's just not always the one built with the target SDK.

I can file a separate bug about the iOS Simulator/Device case

<https://bugs.webkit.org/show_bug.cgi?id=171835> is tracking the iOS device and iOS simulator bits.

Talking about this more, Jonathan and I think that this should be conditional, to match production builds. It's not right that release/debug builds ImageDiff, but production does not.
