Bug 91079 – REGRESSION (r120361) It broke the build within Xcode.

• Component: WebCore Misc.
• Status: RESOLVED FIXED

[Alexis Menard (darktears)]

When launching the build of WebKit within Xcode (after opening the WebKit workspace) it fails to generate properly the files from the IDL.

I have this error :

"Shell Script Invocation error : SupplementalDependencies.dep : No such file or directory" when generating the Derived Sources.

make emits this error, then continues to make the file and includes it. My version of Xcode reports the message, then after make finishes shows this message
    Command /bin/sh emitted errors but did not return a nonzero exit code to indicate failure
then continues building.

Which version of Xcode are you using?
Which scheme are you building in Xcode?
If you change this line in WebCore/DerivedSource.make
    include $(SUPPLEMENTAL_MAKEFILE_DEPS)
to say
    -include $(SUPPLEMENTAL_MAKEFILE_DEPS)
(prepending a hyphen), are you able to build successfully?

Xcode 4.3.2 from the Mac App store.

All Source in Release for example.

Once you hit the error, if you build again, do you hit it again, or is the file still missing?

This unrelated and seemingly incorrect.

Still missing.

True it is unrelated. I'm not familiar with the code/format there. What is incorrect?

In that case, the proposed patch is merely papering over the problem.  Can you attach your full build log up to the error so that maybe someone can identify the issue?

The scheme literal syntax is a single ' prefix. I think the trailing ' would become part of the literal, thus referring to a different object.

Sorry I take back what I said. It doesn't display the error anymore.

So it's only the first time that it happens.
