cross-compiling modules for a preemptive kernel(2.6.23)

Hi all,

I have linux-2.6.26 preemptive and busybox running on an ARM9

Im trying to run an hello world module but I get the error:
"helloworld: version magic '2.6.23 mod_unload ARMv5' should be '2.6.23 preempt mod_unload ARMv5'"

I have the same version of kernel source tree but i dont know how i compile for a preemptive kernel.

The kernel on the ARM is not made of this source tree, i assume that somewhere there must be a change in the source tree when you compile an preemptive kernel?

And why is there actually 'mod_unload' in the version number of the modules?


Thank you in advance

Hi u u have to make two changes in your kernel Makefile . first in the kernel makefile set ARCH=arm and CROSS_COMPILE= set_your_toolchain_path u use for ur cross_compiler.and then compile ur kernel by using "make defconfig".


and in the Makefile of ur module set ur kernel path to this one. and then compile ur module. it should work.
warm regards,
Ravi Kulkarni.
