Re: Kernel Module - Raid

All,

So I was able to get the Adaptec kernel module uncompiled (YES! :)). I
followed the instructions and now when I run 'make menuconfig' I see
that I can make the ADPAHCI a module of the kernel under Device Drivers
- -> SCSI (I belive) -> Low-level -> ADPAHCI. Everything to this point is
nice and happy.....However, when I start to compile the kernel I get the
following error once it gets to drivers/scsi/adphaci:

Sorry for the long output, but that is the entire error so I included
the whole thing.

I guess the thing I am looking for is to ask if anyone else on this list
has successfully compiled Adaptec modules into the kernel before. I am
also wondering why there are so many errors and undeclared functions. I
did follow the instructions that came with the module and have even
tried over and over again. Thanks.
