multiple definition of `__module_kernel_version'

multiple definition of `__module_kernel_version'

[Timur Tabi]

I'm trying to port my driver from 2.4 to 2.2.  When I try to compile it, I get
several "multiple definition of `__module_kernel_version'" errors:

I've searched through the mailing list archives, but none of the "fixes"
suggested earlier seem to work.  Why does this happen?  And why doesn't it
happen with 2.4?

include/linux/module.h was changed in the 2.3 kernels to define
__module_kernel_version and __module_using_checksums as static.
Without that change you get multiple definitions of the variables when
you link multiple objects into a single module.  In 2.2 you have to
#define __NO_VERSION__ before including module.h in all of the module
objects except one.  Search 2.2 drivers for __NO_VERSION__ to see
examples of this.

If I do that, I get this error:

../support/schedule.h:16: parse error

and line 16 says:

#if LINUX_VERSION_CODE < KERNEL_VERSION(2,3,0)
