7 years ago The coap-server is only a component; it can't be built alone. But, you can disable most of the components if you don't want to work with them. The README file tells you how to do that.
Then, you must build the entire example project:
make clean all BOARD=launchpad/cc2650
I am completely new to contiki and embedded development (just a little experience with Arduino).
I cloned contiki on a Ubuntu 17.10 VM and can compile and run simple applications to make an LED blink. I cannot compile the coap-server example: /home/josh/contiki/examples/cc26xx/cc26xx-web-demo
Here is the command I am using to make:
sudo make clean TARGET=srf06-cc26xx BOARD=launchpad/cc2650 coap-serverHere is what I get near the end of the process when it fails the build:

Any idea's why? It is not obvious to me. Thanks!
