# modinfo iio_dummy_evgen.ko filename: /home/simran/git/kernels/staging/drivers/iio/dummy/iio_dummy_evgen.ko license: GPL v2 description: IIO dummy driver author: Jonathan Cameron <jic23@xxxxxxxxxx> srcversion: A8AC238EC07833E018CAF7B depends: industrialio intree: Y vermagic: 4.11.0-rc1+ SMP mod_unload modversions $ uname -r 4.10.0-rc3+ So, this shows that I need to compile module iio_dummy_evgen.ko for kernel version 4.11.0-rc1, so for this I need to build system and source tree for this version. So, I am trying this:- make -C /lib/modules/4.11.0-rc1+/build M=drivers/iio/dummy/ iio_dummy_evgen.ko But I don't know why I am getting this error:- make: Entering directory '/home/simran/git/kernels/staging' make[1]: *** No rule to make target 'iio_dummy_evgen.o'. Stop. Makefile:1664: recipe for target 'iio_dummy_evgen.ko' failed make: *** [iio_dummy_evgen.ko] Error 2 make: Leaving directory '/home/simran/git/kernels/staging' On Tue, Mar 14, 2017 at 12:19 AM, <valdis.kletnieks@xxxxxx> wrote: > On Mon, 13 Mar 2017 15:38:07 +0530, SIMRAN SINGHAL said: > >> >> # modinfo iio_dummy_evgen.ko >> >> filename: > >> >> vermagic: 4.11.0-rc1+ SMP mod_unload modversions >> >> >> >> >> >> $ uname -r >> >> 4.10.0-rc3+ > >> Greg, I got that I have to build the module against the kernel I am using. >> But, How can I do this? > > You can do this in two different ways: > > 1) You're running a 4.10.0-rc3+ kernel.
