Hi ALL,
I got unexpected issue: my kernel extension doesn't get loaded on Mac OS X 10.4.11 PPC. kextload utility outputs the following:
sudo kextload -t -v 6 /System/Library/Extensions/MyDriver.kext > kextload.log
Password:
kld(): /System/Library/Extensions/MyDriver.kext/Contents/MacOS/MyDriver load command 2 unknown cmd field
kextload: kld_load_from_memory() failed for module /System/Library/Extensions/MyDriver.kext/Contents/MacOS/MyDriver
kextload: a link/load error occured for kernel extension /System/Library/Extensions/MyDriver.kext
load failed for extension /System/Library/Extensions/MyDriver.kext
(run kextload with -t for diagnostic output)
This is the error message (I don't include kextload.log file content because it doesn't shed light on the problem).
MyDriver.kext contains executables for 3 architectures: ppc, i386 and x86_64, however the issue occurs with PPC arch only.
It's built with Xcode 3.2.4 (or so) on SL 10.6.7 using SDK 10.4u (SDK 10.6 is for x86_64 arch only).
This is because the Mach-o file has the UUID field in and the PPC kernel on 10.4.x doesn't understand it. This is a result of using the linker included with the newer Xcodes. You have to add the following build setting to the project for the ppc build: OTHER_LDFLAGS = -Xlinker -no_uuid That one stumped me for a while when I ran into it. Best regards, B.J.
