Hi,
It works for me. Do you have a kernel .config file?
Does it set/enable CONFIG_IIO and some/any/all drivers in drivers/iio/accel/ ?
If you don't have a kernel .config file, I don't expect it to work.

Hey Randy,
I do have a .config file but no it does not set "CONFIG_IIO".
The weird thing is when I built the kernel initially the object files
for drivers/iio/accel/ were generated.
That's strange right?
Thanks for helping!

Sounds like you now have a different .config file and that the earlier
.config file did enable CONFIG_IIO.

Hi Rohit,
The required config options need to the objects in that folder to be
build. Apparently there is no way to automatically set the required
configs. You can look at the Kconfig files inside drivers/iio/accel
and see what are the dependencies for building various drivers.

It looks like some of the drivers are individual files. So you can also
just compile them one at a time make staging/drivers.iio/accel/foo.o.

Hey julia,
I ran a `make clean` on that directory by mistake which I realised I
shouldn't have done. Hence no object files are there.
Giving me this:
`
make drivers/staging/iio/adis16240.o staging/git/remove-include
CALL scripts/checksyscalls.sh
CALL scripts/atomic/check-atomics.sh
DESCEND objtool
make[1]: *** No rule to make target 'drivers/staging/iio/adis16240.o'. Stop.
Makefile:1772: recipe for target 'drivers/staging/iio/adis16240.o' failed
make: *** [drivers/staging/iio/adis16240.o] Error 2
`
I guess I will have to enable `CONFIG_IIO` and rebuild?
Although what I don't understand is if `CONFIG_IIO` was not enabled how
were there object files in the first place?
Thanks,
Rohit

Perhaps the build system is just not very well designed here.
However, for me
make allyesconfig
make drivers/staging/iio/
works, and after that it is possible to do:
make drivers/staging/iio/accel/adis16203.o
I didn't do anything explicitly with CONFIG_IIO.

That 'allyesconfig' enables CONFIG_IIO.

Perhaps you have already compiled the .o files that are used to produce
these .a files? There seem to be some files that are simply not possible
to compile. Perhaps they can be compiled for some other architecture.
But you can also just work on the files that you are able to compile.

Hi,
Would you follow below steps to build kernel source?
1) Download latest linux kernel source tree:
git clone https://kernel.googlesource.com/pub/scm/linux/kernel/git/next/linux-next.git
2) Generate kernel config(allyesconfig):
cd linux-next
make arch=x86_64 allyesconfig
3) Build kernel Source as you mentioned:
