Hi all, This list has helped me wrangle with some of the pitfalls with kernel extensions. Thanks to those who have provided input at various times. At present, I have a working kext for Jaguar. I'm now trying to create a version for 10.1.5. As far as I can tell, we should be able to support 10.1.5. At this point though, I'm encountering some "resistance". I found that the 2.9.5 GCC compiler used by PB, shipped with the 10.1.5 Dev tools, choked on the code. I think it should have been able to handle it, but it's not happy. For instance, I use a debugging macro with a variable arguments list, and it doesn't know how to handle it. It would be a nightmare for me to rewrite this code to suit that compiler. I was advised to obtain the April 2002 Dev tools, containing a pre-release version of PB that supports the GCC 3.1 compiler and that will run on 10.1.5. I obtained it and added the appropriate build setting to my project to compile with with GCC 3.1. The kext appears to build fine. Unfortunately, when I try to load it, I get a crop of undefined symbol errors like these: kmodload: __ZN11OSMetaClass21_RESERVEDOSMetaClass0Ev kmodload: __ZN11OSMetaClass21_RESERVEDOSMetaClass1Ev kmodload: __ZN12IOUserClient10getServiceEv kmodload: __ZN12IOUserClient12initWithTaskEP4taskPvmP12OSDictionary kmodload: __ZN12IOUserClient13connectClientEPS_ kmodload: __ZN12IOUserClient15mapClientMemoryEmP4taskmj kmodload: __ZN15IORegistryEntry26_RESERVEDIORegistryEntry18Ev kmodload: __ZN15IORegistryEntry26_RESERVEDIORegistryEntry19Ev kmodload: __ZN8OSObject19_RESERVEDOSObject19Ev kmodload: __ZN9IOService12didTerminateEPS_mPb kmodload: __ZN9IOService12getBusyStateEv This leaves me with two questions... a) Is it safe to use the version of the pre-release GCC 3.1 compiler shipped with the April 2002 Dev tools? b) All of the undefined symbols I see seem to be IOKit related. Anyone know what's up with this? How to get around the problem? Thanks in advance, Eric Long _____________________________________________________________________ In the movie, Jon Lovitz will play the Iraqi Information Minister. _______________________________________________ darwin-kernel mailing list | darwin-kernel@lists.apple.com Help/Unsubscribe/Archives: http://www.lists.apple.com/mailman/listinfo/darwin-kernel Do not post admin requests to the list.
