Solved by including "wtf/spi/cocoa/objcSPI.h" in deps/jscshim/webkit/Source/WTF/wtf/CMakeList.txt

cd /Users/lolo/Documents/node/iOS/bb/node-jsc/deps/jscshim/webkit/WebKitBuild/DerivedSources/WTF && mig -sheader MachExceptionsServer.h MachExceptions.defs
MachExceptions.defs:26:10: fatal error: 'mach/mach_exc.defs' file not found
#include <mach/mach_exc.defs>
^~~~~~~~~~~~~~~~~~~~
1 error generated.
mig: fatal: "MachExceptions.defs", line 2: no SubSystem declaration

this build error still remains.

Hey, sorry for the late reply, been away for a couple of weeks.
I've noticed the wtf/spi/cocoa/objcSPI.h issue on the v10 branch, but if this is happening on the master branch too, this is a bug. So just to be sure, are you working with the master branch?

Hey I'm experiencing this error, how was this resolved on your end?

Huh, it seems like building WTF for compiling JSC with the --only-jsc breaks the build. Omitting that flag resolves the issue I was experiencing.
