RE: FATAL ERROR: command exited with status 1

Hello

I got exactly the same error when trying to build, but I was able to figure out what's going on.

The coap_server_client_interface.h file is located at nrf/samples/openthread/coap_server/interface/

This file is included into the coap_client sample by this line in CMakeLists.txt:

target_include_directories(app PUBLIC ../coap_server/interface)

The problem is that this inclusion is done through a relative path from your application folder, which is correct in the sample folder structure, but when you make a copy of the sample into your application folder this inclusion path finds nothing.

Unless you compile the coap_server sample first, which will generate the same folder structure in your application folder, which will let you compile the coap_client sample successfully afterwards.

I suggest you use this workaround now, or you could alternatively copy the coap_server_client_interface.h file into your src directory and update CMakeLists.txt accordingly.

Either way I'll let the developers know of the issue.

Best regards,

Einar
