I think ninja is failing because there's no explicit output for WatchApp.app

[dmpatierno, 2014/12/03 23:09:48]

I can get the test to pass with ninja now, but I've been unable to find a
configuration that both ninja and xcode are happy with. If I force
SDKROOT=iphonesimulator8.2, xcode succeeds and ninja fails. If I remove the
simulator-specific lines, ninja succeeds and xcode fails. It looks like the
"extension" test just does the latter and fails for xcode runs. For now, I've
updated the watch test to do the same.

Any ideas?

[justincohen, 2014/12/04 17:21:36]

It works fine for me if I run from within Xcode, and not from the command line
gyptest.  sdefresne pointed out that gyptest messes with $HOME which breaks
security's ability to load the provisoining profiles.  He suggested you need to
create ${TEST_BASE}/Library/Keychains and copy recursively the content of
~/Library/Keychains there.   probably the same thing for "$HOME}/ 

Or just make sure it works in Xcode natively....

The extension.gyp is missing 'CODE_SIGN_IDENTITY[sdk=iphoneos*]': 'iPhone
Developer' for both targets.  If I add them there, extension also passes when
run natively in Xcode.  I don't think sdefrense@ would object if you add those
two lines, e.g.

Doesn't this need Foundation.framework too?

[dmpatierno, 2014/12/03 23:09:48]

The simple reference app I made does not include the Foundation or UIKit
frameworks anywhere in the project file. I think Xcode 6 will parse the source
and add them automatically, so it doesn't actually need them here, but I agree
being explicit is better. Added.

Any idea why this shows up as a red (file not found) when opening in Xcode?  
Everything seems to link correctly, so I can't tell if it's a real problem.

[dmpatierno, 2014/12/03 23:09:48]

I noticed this too. Everything compiles, runs, and works though. No idea why
Xcode colors it red.
