I am facing issue for compilation of the code. please find the steps which I have executed below.

Steps:

1. Installed the arm tool chain with the below command
   -> sudo apt install gdb-arm-none-eabi
2. Downloaded the code from git and unziped it.
3. Inside the folder
   -> cd burba
   -> git clone https://github.com/RIOT-OS/RIOT.git
   -> cd apps/hello-world
   -> make

   Output

I could not find the file "sockloop.h" in the source code. Please let me know if I need to install any other components on my Ubuntu?
It does not find the definition for "sockloop_run()" function too.

My another observation
The makefile "NAIS-master/burba/apps/hello-world/Makefile" is included the below line
-I$(BURBA)/sys/protobuf-c
but from the git it does not present this folder/file at all in the specified path.
