Hi,

I suggest to do 'make clean' again and start from scratch.
Run 'make menuconfig' and make sure the settings look like this= :
{*} Industrial I/O support ---> (instead of module, make this built-= in,
use 'y' instead of 'm')
<Descend this option where you'll configure configfs, dummy, etc= >
{*} Enable IIO configuration via configfs (use 'y' instead of &= #39;m')
<M> Enable software IIO device support
<M> Enable software triggers support

Under IIO dummy driver:
<M> An example driver with no hardware requirements
[*] Event generation support
[*] Buffered capture support

Compile and install, then boot to that kernel and test if it works.

Hi,

I am able to insert module iio_dummy_e= vgen.ko but when I run
$ sudo insmod iio_dummy.ko

I got the follo= wing error:
insmod: ERROR: could not insert module iio_dummy.ko: Unknown= symbol in module

And in dmesg I am getting following error:
iio_= dummy: Unknown symbol iio_register_sw_device_type (err 0)

Any Idea?=
