After addressing previous build issues, webkit-gtk 2.11.3 succeeds in building the release configuration.  When building the debug configuration, it fails when linking libjavascriptcoregtk:

Undefined symbols for architecture x86_64:
  "JSC::JSCell::inherits(JSC::ClassInfo const*) const", referenced from:
      JSC::WriteBarrierBase<JSC::Structure>::set(JSC::VM&, JSC::JSCell const*, JSC::Structure*) in StructureStubInfo.cpp.o
  "JSC::JSCell::structure() const", referenced from:
      JSC::WriteBarrierBase<JSC::Structure>::set(JSC::VM&, JSC::JSCell const*, JSC::Structure*) in StructureStubInfo.cpp.o

webkit-gtk was configured as:

Looks like it's supposed to be from runtime/JSCellInlines.h

inline bool JSCell::inherits(const ClassInfo* info) const
{
    return classInfo()->isSubClassOf(info);
}
...
inline Structure* JSCell::structure() const
{
    return Heap::heap(this)->structureIDTable().get(m_structureID);
}

I suspect this is from one of the various ASSERT()s in some header.  I didn't track down where it was, but adding '#include "JSCellInlines.h"' to StructureStubInfo.cpp.o allows me to work around this issue.  That's obviously not the appropriate fix.  The include should be done in the appropriate header that is consuming those methods.

[Jeremy Huddleston Sequoia]

Ah, I think it is coming from this in WriteBarrier.h:

template<class T> inline void validateCell(T cell)
{
    ASSERT_GC_OBJECT_INHERITS(cell, std::remove_pointer<T>::type::info());
}

by way of WriteBarrierInlines.h:

inline void WriteBarrierBase<T>::set(VM& vm, const JSCell* owner, T* value)
{
    ASSERT(value);
    ASSERT(!Options::useConcurrentJIT() || !isCompilationThread());
    validateCell(value);
    setEarlyValue(vm, owner, value);
}

Testing a fix.

Dang.  Messy layering issues...

Including JSCellInlines.h in WriteBarrier.h results in:

This is no loner an issue in 2.15.1
