This modules has been tested in Strech with kernel 4.9.59-v7+

To revert the kernel version sudo apt-get install --reinstall raspberrypi-kernel sudo reboot

you should sure you have the headers for compiling modules sudo apt-get install raspberrypi-kernel-headers raspberrypi-kernel

I have the same problem with Strech kernel 4.14.26-v7+:

make -C /lib/modules/4.14.26-v7+/build M=/home/pi/matrixio-kernel-modules modules
make[1]: *** /lib/modules/4.14.26-v7+/build: No such file or directory.  Stop.
Makefile:17: recipe for target 'all' failed
make: *** [all] Error 2

I think it's after

rpi-update

because I have the directory build in /lib/modules/4.9.80+ and 4.9.80-v7+ but not in /lib/modules/4.14.26+ and 4.14.26-v7+ And i don't have linux-image with kernel 4.14.26

I find a solution i downgrade kernel with rpi-update and the commit ID of kernel 4.9 ( Find all commit here page )

sudo rpi-update 5c80565c5c0c7f820258c792a98b56f22db2dd03

And this compile and install :)

Hello @Ultchad

Thank You for your feedback! I will add kernel information in the README, in order to be more clear about the proper environment.

Regards,

Even after downgrading to kernel 4.9.57-v7+, I still get Error 2:

dtc -W no-unit_address_vs_reg -@ -I dts -O dtb -o matrixio.dtbo matrixio-overlay.dts make -C /lib/modules/4.9.57-v7+/build M=/home/pi/matrixio-kernel-modules modules make[1]: /lib/modules/4.9.57-v7+/build: No such file or directory. Stop. Makefile:18: recipe for target 'all' failed make: [all] Error 2

What can I do to fix this?
