Re: module compilation on 2.6

Rick,
Thanks for the reply. Should the module code be physically located inside the kernel source tree(/usr/src/linux-kernel-version??)?
I had a module built outside kernel tree on 2.4. Things compiled OK. I want to check itout (using the same make commands) on 2.6 and I get bunch of errors.
Is irq_vectors.h automatically picked by kernel using some variable?

If the module's source is designed correctly, it'll look for the kernel headers it needs by looking at /lib/modules/`uname -r`/build. Under 2.4, this is generally a symlink to the actual kernel source directory. In 2.6, it's typically a directory that contains all of the necessary source (headers and whatnot) to build your module.

The trick is that the module MUST be designed with 2.6 in mind.  A quick
search for the file you have problems with lists four "irq_vectors.h"
files based on the basic system architecture, "mach-default",
"mach-visws, "mach-voyager" and "mach-pc9800".  The module's Makefile
must understand this to grab the right file.

So providing the module is 2.6-aware, yes, you should be able to build
your module outside the kernel source tree.  I know it works as I've
built several drivers that way (for example, the atmel driver for
atmel-based wireles LAN cards).

    2.6 kernel building is a lot different. Your best bet is to do it
    from ground zero:

    # cd /usr/src/linux-whatever
    # make mrproper
    # make xconfig -or- make gconfig -or- make menuconfig
    (load an existing config file or set things up as you wish)
    (save this new config)
    # make
