and this is common , because there is no config.h header file in 2.6.22 ( but there is one in 2.6.10 ) .
after removing config.h from scull's source , you get lots of new errors ... .
so , compiled scull with 2.6.10 headrs like this :got no error but , at the runtime insertion (insmod) get this error :
>( modified Makefile's scull ) :
>KERNELDIR ?= /lib/modules/2.6.10/build<3>scull: version magic '2.6.10 SMP preempt 686 gcc-4.1' should be '2.6.22.9 SMP preempt mod_unload CORE2 'and this error is reasonable too . api and interfaces has been changed since 2.6.10 ( am i right? )
anyway , as i'm new to drivers ... , so first compiled gcc-3.4.3 and binutils-2.15 and now i can compile 2.6.10 to run scull . maybe try to port scull to new kernel versions (as a case study ) next time ...
