Hi, i was working with this project where i'm trying to make the thingy53 a thread node.

when i build i find this error and i don't know why:

Hi,

Thank you for contacting DevZone at NordicSemi.

As per the information you have provided, I started with:

1) VS Code and selected nCS v2.1.1 as the SDK version and 2.1.1 as the toolchain version

2) Then I created the new project and selected "coap_server" sample

3) I built if for thingy53. Build was successful without any issue/problem.

What I see is that your project is not very similar to this sample. For example, the sample has "coap_server.c" in the "src" folder while your project has "main.c", and their contents are also not similar.

Moreover, another thing, which could be causing error in your case, is that the #include are different in your project.

For example, the sample has:

#include <zephyr/net/openthread.h>

while your project has:

#include <net/openthread.h>

And, it is very this header file that contains the inclusion of instance.h

So I suggest you to look into the code and structure of the sample project and then after successful compilation integrate your changes to the sample code.

Let me know if this helps or there is something I am missing.

Regards,
Naeem

i modified the #include path as you said to me but the same error persists.

as well i can build a project like server_coap for thingy53 and it works fine.

i don't know how to solve this

[simon8]

i think the problem it's something related to this path #include <zephyr/net/openthread.h>

bacause when i build this porject without that line ends up well. when i write that line on the code, returns the same error on 

#include <openthread/instance.h>

Hello,

But if that is the problem then how can we build "coap_server" for thingy53?

I tried with your sample as well. Somehow this error disappears, and then new different errors occur.

Can you start integrating your changes into the working sample (coap_server) and then see what changes makes or break the compilation.
