Undefined reference error while trying to use out-of-tree driver

[Quard]

I have create small project with a sensor driver that does not exist in main source tree. But when I trying to compile it I have an error undefined reference to `__device_dts_ord_84'.

Based on a error message it seems like driver is not a part of final linkage command and I could not find how to add it. I have checked a few different repositories that implements out-of-tree drivers and they are looks similar for me.

Code available github.com/.../si1145-drv-demo.

Thanks ahead.

Hi  Vadym

Which version of NCS are you using?

I downloaded your application and compiled it with NCS 2.3 without any problems. Try to delete your build folder and do a prestine build.

I have exactly the same version of NCS but I it was updated few times, I believe that initially was installed something like 1.9. Also I noticed that 2.4 was released and try it but result the same.

Update was done by such set of commands

git fetch origin
git checkout v2.3.0
west update

I will try to reinstall environment from scratch and will notify if I have any success.

I would perhaps recommend using the toolchain manager if you need multiple versions of NCS, but that is more of an personal preference. 

Try to delete the build folder and do a prestine build before you remove everything. 

You could also try with an west update inside your 2.3 folder

Yes, each time before the build I deleted the build folder. And I do not use a few versions of NCS on a machine, just one which I update to the latest version.
