Using the new method for building a standalone kernel module (although seems to happen with the traditional way as well) I get "mach_mpspec.h: No such file or directory"

Same result if I try to do a kernel 'make'.

Subsequently I get MAX_MP_BUSSES and MAX_IRQ_SOURCES undeclared.

This should surely work 'out of the box' with Centos ?

Any ideas about what's missing ?

You don't like the kernels I build ?

I have been out of driver development since late 2.4 and was unfamiliar with the 'new' kernel module build procedure, which uses the kernel build makefile ("make -C $(KERNELDIR) M=$(PWD) modules") rather than just doing a gcc on the module with a few extra flags.

Hence did not know why I was getting an error in an apparently 'vanilla' build, which I thought should work with just the kernel dir being specified.

I could see the file in question existed in another dir, but thought it was not a true 'fix' to just add that path to the include paths.

I imagine I am missing something like an ARCH setting or something, but have not seen anything documented about setting this.

I also note from Googling that others have had the same error, (not necessarily with Centos, so it's not a distro problem) but suggestions for them usually involved "install kernel source", obviously not required in my case - in any case the headers should suffice.

Thanks, MikeW
