Compiling 2.6.23: implicit declaration of function ‘scsi_device_cancel’
 

This is the end message that I get after 'make modules'

drivers/scsi/rr174x/os_linux.c: In function ‘os_sd_changed’:
drivers/scsi/rr174x/os_linux.c:315: error: implicit declaration of function ‘scsi_device_cancel’

If you do not need the RR174X module then set it to =n in your config and the error will go away plus why are you doing the compilation without the make-kpkg program it is an easy way to get a .deb file that you can install with dpkg -i linux-image-??????.deb.

I will look into the make-kpkg. Thank You. I however do need the RR174X module - this being the reason why I am working with the 2.6.23 kernel. My present kernel, 2.6.18, doesn't recognize the High Point RocketRaid Controller.

That sucks then its always the one you need that does not compile. BTW where are you getting that option for it from have you patched your kernel?? Because looking at my .config for a 64bit kernel it does not appear anywhere in it but looking at the section in menuconfig I see the CONFIG_SCSI_HPTIOP is for the Rocket Raid 3xxx series perhaps it may be worth looking at if you have similar. Other than this I would suggest email the author of the module his/her email should be in the comments of the module source file.

Edit: The proper name for the make-kpkg program for installation if you want it is the kernel-package package.

You’re not making any sense. No vanilla kernel has support for rr174x. In order to get that particular module, you have to download sources from here. With those patches, you can chose either to patch your kernel source, or compile an out-of-tree module. Regardless, there is nothing in the instructions about the using kernel 2.6.23 or greater.

Anyway, it seems you must use a kernel with a version less than 2.6.23 (unless you want to do more patching). The mentioned function has been removed from 2.6.22 to 2.6.23.

Solution:

1. Use the patch on a kernel with version 2.6.22 or less.
2. If you still want to use the 2.6.23, apply this patch in reverse to the kernel sources. Here is a copy-pastable (and forward) version:

   Note that this is only a quick-fix and won’t necessarily work with newer kernels. The appropriate fix would be from the vendor.
