scpi-server issues

[simone.mannori]

I have just finished my first FPGA complete design (lock-in amplifier) starting with http://antonpotocnik.com/?p=487360 tutorials. I would like to customize the scpi-server and scpi-parser code in order to support my new custom instruments and make it available to Matlab clients.
I have a fresh & clean Ubuntu 16.04 installation (Virtualbox). For start, I ha followed the instructions here:
http://redpitaya.readthedocs.io/en/late ... cpi-server.
"make api" works without errors BUT it does NOT produce any "scpi-server/scpi-server " executable.
Therefore, I have cloned the scpi-parser and compiled it successfully.
Then, I have tried to compile manually the scpi-server with "make clean all".
Unfortunately the compilation stops with several errors and warnings (please see below for the details).

Question:"What I need to do in order to recompile (cross-compile) the code from the source?"

Thanks in advance for your help ...
