Re: Compatibility of IOKit drivers

I'm updating an IOKit driver that was written a couple of years ago to support some new hardware. It loads OK on a G5 machine running OS X 10.4.10 but not on a G4 machine running 10.4.6. The driver itself was originally built on a 10.4.3 G5. However I built the new version on a 10.4.10 Intel machine as a universal binary.

I am a little bit confused as to why this is the case. I thought building as a universal binary might be the issue, but the reported errors don't seem to suggest that.

Any suggestions?

Building a universal I/O Kit driver is a bit tricky. Have you followed the advice from TN2163?
