I am trying to recompile Superhai's GenericCPUPM to Snow. For 32 bit it works but the message
QUOTE
Warning - kext com.superhai.driver.GenericCPUPowerManagement has immediate dependencies on both com.apple.kernel* and com.apple.kpi.* components; use only one style.

In 64 bit it is error.

If I exclude such dependencies then

Is there anybody knows what to do if a kext has kernel dependencies?

Yes, you add the dependencies to the Info.plist or remove the dependency from the source. Here you need to find an alternative to IOCPU::metaClass as only apple signed kext are allowed to use com.apple.kpi.private in which IOCPU::metaClass is. If I will guess it is because of the IOKit "rtti" OSDynamicCast that causes the problem.

The next question however is why are you compiling this old source?

With those sources I have working GenericCPUPMControl.app which is fine. You mean that VoodooPower is better? I have no full functional sources of it. Is it possible to rewrite VoodooPower for Snow64 and use the app with it?

I think I can replace a class IOCPU with my own class including full implementation. Or may be it is better exclude the class at all. I didn't decide yet.

Hi Slice

I also tried to compile SMBIOSResolver from SuperHai's source, ang 32bit is working in Snow. But not in x64.
I think it has the same issue like this.
Can you help me.
Thanks

Yes I know it's none of my business...but why would you want to use SMBIOSResolver when you can use vanilla AppleSMBIOS.kext and set all that stuff in /Extra/smbios.plist.

Hi Gringo

Im using HP 110 Netbook, Have to use SMBIOSResolver to get rid of "Error getting reference to IODeviceTree:/Options".
Other thing is, Using UUID fix in smbios.plist or com.apple.boot.plist doesnt do anything. Still have to use PlatformUUID kext.

But using SMBIOSRResolver, it solved the 2 issues i mentioned above. I hope i explained it well smile.gif

I know the 32Bit of SMBIOSResolver will do just fine on my Netbook, since its only32bit. But my point here is, i just would like to have a Universal kext of it.

Please help

I think you use bad bootloader.
Good one create /Options and correct UUID.
No future for SMBIOSresolver.

Hi Slice

I agree. But i think it would be an easier fix for me if i do it in SMBIOSResolver, rather than in chameleon.

Can you help me out by fixing the kernel dependencies in the source?

Thanks smile.gif

While waiting for someone to help, try Asere's variant of Chameleon 2.0 RC4:

If you're already running Chameleon 2.0 RC4 you can just drop in the boot file.

Thanks for the effort Gringo. I really appreciate it. smile.gif
