the same error with @williamgdev @marva2013

[foolfrog]

the last param for function recvfrom/accept/getsockname not match, modify to (socklen_t*)socklen_t may fix the error.

You need to specify c++ compiler flag, -DSOCKLEN_T=socklen_t
Cause thats just a preprocessor variable

set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11 -fno-rtti -Wall -fexceptions -DXLOCALE_NOT_USED=1 -DNULL=0 -DNO_SSTREAM=1 -DSOCKLEN_T=socklen_t -UIP_ADD_SOURCE_MEMBERSHIP")
