Please help!

Hello guys,

Brand new to Transfercoin and I'm really struggling to get the software up and running.  So far I've tried and failed on a RPi3, Odroid C2 and in Linux Mint.  I'm fairly new to Linux but usually find a guide online to get around problems like this but this time I'm completely lost and would really appreciate some help.

Whilst compiling from Github, after the command, 'sudo make -f makefile.unix # Headless transfer'

I get;

 'g++ -c -O2  -pthread -Wall -Wextra -Wno-ignored-qualifiers -Wformat -Wformat-security -Wno-unused-parameter -Wunused-function -Wunused-variable -fpermissive -Wconversion-null -g -DBOOST_SPIRIT_THREADSAFE -I/home/***/Desktop/transfercoin/src -I/home/***/Desktop/transfercoin/src/obj -DUSE_UPNP=0 -DUSE_IPV6=1 -DENABLE_WALLET -I/home/***/Desktop/transfercoin/src/secp256k1/include -I/home/***/Desktop/transfercoin/src/leveldb/include -I/home/***/Desktop/transfercoin/src/leveldb/helpers -DHAVE_BUILD_INFO -fno-stack-protector -fstack-protector-all -Wstack-protector -D_FORTIFY_SOURCE=2  -MMD -MF obj/alert.d -o obj/alert.o alert.cpp
make: g++: Command not found
makefile.unix:217: recipe for target 'obj/alert.o' failed
make: *** [obj/alert.o] Error 127

( ive replaced a folder name with *** )

I get this error on all of the different systems and hardware that I'v tried.  From Github  I can see that, " Transfer uses libsecp256k1, libgmp, Boost1.55, OR Boost1.57, Openssl1.01p, Berkeley DB 4.8, QT5 to compile."

Is this where I'm going wrong?  I have tried to install them but cannot and I guess they're not available in the repositories I have installed.  Please can somebody offer some advice or where to easily locate all of these packages if this is indeed the problem?

Thanks in advance.
