Re: kernel debug assert



_Assert is only exported via com.apple.kpi.libkern v8.0 (and later).

The "compatibility" libs refers to the com.apple.kernel.* identifiers (< v8.0) that represent our binary compatibility library for pre-Tiger kexts.

Unfortunately, _Assert is not provided in these libraries, so you'll either need to move to the KPI interfaces, or remove your dependence on _Assert.

Cheers,

Yes, I am using Tiger.
Sorry for being such a newbie, but what do you mean by compatibility libs?
What should I be using as libs?
Can I make my own assert that calls panic?  What do I need to make that work.
I am a little discouraged with myself, I can't even get a kext with assert(0) to work.  
Thanks,
Anthony

Are you running in Tiger?  I had a similar problem where I couldn't link to _Assert when running in Tiger.  It used to work fine in earlier systems.  I *think* that this may be defined in libkern for Tiger, but not if you're using the older compatibility libs like you are.  You might have to do Tiger and pre-Tiger specific builds.  In my case I just stopped using _Assert.

I have looked everywhere.  I still can't find who exports the _Assert?
Is no one using IOKit/assert.h?

Ok, I defined MACH_ASSERT in my project, but now my kext doesn't load.
undefined symbol _Assert
What library (and version) is this in?
I already have these in my info.plist:
com.apple.iokit.IOPCIFamily 1.4
com.apple.kernel.iokit 6.9.9
com.apple.kernel.libkern 6.9.9
com.apple.kernel.mach 6.9.9

Hello developers,
I am trying to find some info on helpful kernel debug macros.
I found "assert" in <IOKit/assert.h> , but it doesn't seem to do anything; probably because MACH_ASSERT in <kern/assert.h> is not defined.
What is the proper way of using this marco?  Do I just define MACH_ASSERT  in my project settings?
Is there a pre-defined DEBUG symbol? Or do I have to add this to my "development" profile in Xcode?
Thanks,
Anthony
