After creating a new Ubuntu virtual machine to start fresh, I am still experiencing the issue below.
I re-installed the Connect SDK manually on the new virtual machine as instructed here (using v1.9.1). When I try to build the attached basic application ("west build -b nrf9160dk_nrf9160_ns"), I receive the error output below.
Just last week, I was including "CONFIG_CJSON_LIB=y" in my prj.conf and "#include <cJSON.c> #include <cJSON_os.h>" in my main.c and building without issue. Could you please help me resolve this duplicate functions issue?
Thanks.
