site_archiver@lists.apple.com Delivered-To: darwin-kernel@lists.apple.com Hi Alexey, (no need to require 10.4.1, so 8.0.0 will do) Unfortunately there seem to be no matches for sysctl__hw_children: So you'll probably have to work out how to avoid using it in your kext.

After upgrading to Tiger/Xcode 2.0 I receive this errors with loading my kext: kextload: sending 1 personality to the kernel kld(): Undefined symbols: _sysctl__hw_children _sysctl_register_oid _sysctl_unregister_oid kextload: kld_load_from_memory() failed for module What I need to make it work on Tiger? _______________________________________________ Do not post admin requests to the list.

First you need to find out what your kext's kernel dependencies are. There were a couple of threads about this back in April on this list. Essentially, to find your two "oid" symbols: % cd /System/Library/Extensions/System.kext/PlugIns % find . -type f -a ! -name "*.plist" | xargs nm -o | egrep 'sysctl_ (un)?register_oid' ./BSDKernel.kext/BSDKernel: U _sysctl_register_oid ./BSDKernel.kext/BSDKernel: U _sysctl_unregister_oid % cat BSDKernel.kext/Info.plist | grep -A1 CFBundleIdentifier <key>CFBundleIdentifier</key> <string>com.apple.kpi.bsd</string> % cat BSDKernel.kext/Info.plist | grep -A1 CFBundleShortVersionString <key>CFBundleShortVersionString</key> <string>8.1.0</string> So you need to make sure your kext's Info.plist contains the following dependency in its OSBundleLibraries dict: <key>com.apple.kpi.bsd</key> <string>8.0.0</string> % find . -type f -a ! -name "*.plist" | xargs nm -o | grep sysctl__hw_children Alexey This email sent to site_archiver@lists.apple.com
