Thanks for the reply. I was really hoping to avoid hacking Xcode, but
might resort to that if necessary. The two-system build setup is a
fairly big pain, so I'd like to get this working. Were you having
build (compile/link) or runtime issues with the kext that caused you
to move to this?
I actually thought I had a breakthrough. Analyzing my kext with
kextlibs gave me the following:
jass-macbook-pro:~ jas$ kextlibs -all-symbols
/System/Library/Extensions/mykext.kext/
com.apple.kpi.mach = 9.8.0
com.apple.kpi.libkern = 9.8.0
com.apple.kpi.iokit = 9.8.0
com.apple.driver.AppleSM56KUSBAudio = 1.9.15
com.apple.driver.DspFuncLib = 1.7.1a2
com.apple.iokit.IOUSBFamily = 3.4.9
com.apple.iokit.IOFireWireFamily = 3.4.9
com.apple.iokit.IOFireWireAVC = 2.2.3
com.apple.iokit.IOAudioFamily = 1.6.9fc5
com.apple.driver.AppleUSBAudio = 2.6.4b17
com.apple.driver.AppleFWAudio = 2.4.6fc8
com.apple.driver.Apple16X50Serial = 1.9
2 symbols found in more than one library kext:
__ZdaPv: in SM56KUSBAudioFamily.kext/Contents/PlugIns/AppleSM56KUSBAudio.kext
(1.9.15), AppleHDA.kext/Contents/PlugIns/DspFuncLib.kext (1.7.1a2),
IOFireWireFamily.kext (3.4.9), AppleUSBAudio.kext (2.6.4b17),
AppleFWAudio.kext (2.4.6fc8), Apple16X50Serial.kext (1.9)
kextlibs(257) malloc: *** error for object 0x4f3aa0: double free
*** set a breakpoint in malloc_error_break to debug
__Znam: in SM56KUSBAudioFamily.kext/Contents/PlugIns/AppleSM56KUSBAudio.kext
(1.9.15), AppleHDA.kext/Contents/PlugIns/DspFuncLib.kext (1.7.1a2),
IOFireWireFamily.kext (3.4.9), IOFireWireAVC.kext (2.2.3),
AppleUSBAudio.kext (2.6.4b17), AppleFWAudio.kext (2.4.6fc8),
Apple16X50Serial.kext (1.9)
kextlibs(257) malloc: *** error for object 0x4f3aa0: double free
*** set a breakpoint in malloc_error_break to debug
seeming to indicated that if I just included one of those libs where
the undefined symbols were defined, it'd fix my problem. So, I tried
adding one, then added them all, but *still* get the same undefined
symbols, which is a bit baffling...
