Question

Find the OS X kext library that contains a symbol

Answer 1

A:

Have you tried running kextlibs on your kext? it may give you the correct dependency. Otherwise, it is likely one of the following:

com.apple.kpi.mach
com.apple.kpi.unsupported

see this apple Q&A for more information about the unsupported KPI

Thank you, in addition to com.apple.kpi.mach and com.apple.kpi.unsupported I have added most of the kexts.

I also used both methods that you propose and these methods share the same luck:$ sudo kextlibs rpc_server.kextFor all architectures: com.apple.kpi.libkern = 10.4For i386: 2 symbols not found in any library kext.$ /Developer/usr/bin/FindKPI.py _mig_buckets_mig_buckets not found

There is something strange here because it seems that the symbol is actually exported in the kernel.$ nm -arch i386 /mach_kernel |grep _mig_buckets00844b00 S _mig_buckets

I think mig_buckets is no longer exported, probably part of this ( http://developer.apple.com/mac/library/releasenotes/Darwin/RN-KernelExtensions/index.html#//apple_ref/doc/uid/TP40001023-CH1-DontLinkElementID_11 )
