dosn't compile without lcrypt

[ufehembach]

I'm running ubuntu on raspi: Ubuntu 16.04.5 LTS \n \

Linux MYhomebridge 4.4.38-v7+ #938 SMP Thu Dec 15 15:22:21 GMT 2016 armv7l armv7l armv7l GNU/Linux

all the libs need to be added to compile the codesend

"-lwiringPi -pthread -lwiringPiDev -lcrypt -lm -lrt"

otherwise it runs in the below error.

g++ -c -o RCSwitch.o RCSwitch.cpp
g++ -c -o codesend.o codesend.cpp
g++ RCSwitch.o codesend.o -o ../build/codesend -lwiringPi
