[Openmcl-devel] ffigen4 failing on Mac OS 10.10 (with either SDK)

[Christopher Wicklein]

I’ve resolved these problems as follows:

(1) Grab the 10.8 SDK from an earlier Xcode release and install it along side the 10.9 and 10.10 SDKs (earlier Xcode releases are still available for download from Apple.)

(2) Specify the 10.8 SDK in populate.sh.

(3) The resulting ffigen pukes on its math.h, so I defined “__header_always_inline” as nothing, ifdef’d out a bunch of (mostly) legacy BSD inline function declarations, and I was finally able to process OmniFocus.h (after removing a duplicate declaration of the property “container” in one of its classes.)  Every SDK (10.8, 10.9, and 10.10) resulted in some kind of problem for ffigen, but the problems associated with 10.8 were the easiest to address.  Ugly, but it worked.

For the benefit of anyone who is reading this after a Google search, it turns out that the bundle name for OmniFocus2 (from the App Store) is "com.omnigroup.OmniFocus2.MacAppStore” — not simply “”com.omnigroup.OmniFocus2” as most sources suggest.

? (objc:load-framework "ScriptingBridge" :omnifocus)
NIL
? (defvar *omnifocus-app* (make-instance 'ns:s-b-application :with-bundle-identifier #@"com.omnigroup.OmniFocus2.MacAppStore"))
*OMNIFOCUS-APP*
? *omnifocus-app*
#<OMNI-FOCUS-APPLICATION <OmniFocusApplication @0x608000a46cf0: application "OmniFocus" (17071)> (#x608000A46CF0)>
? (#/buildNumber *omnifocus-app*)
#<NS-MUTABLE-STRING "87.15" (#x608000624340)>

I’m working around what I remember as multiple definitions of the “inline” functions when building ffigen4 with the standard clang-600.0.54.  I’ve omitted the Makefile patch which is used to add my patch to the list of existing patches.  Here’s the patch to toplev.h:

The 10.9 case involves ffigen segfaulting.  The 10.10 case involves a recent change adding the type “instancetype" to Objective-C where I think the previous type was simply “id” confusing the compiler.
