What can i do to correct it i am installing on ubuntu 12.04. please!!!!!!!!!!!!

it seems you don't have gcc compiler installed

Install g++, gcc and make, or simply execute the following command:

sudo apt-get install build-essential

Actually the "cclfox-0.7.1" code is c++ !

And : gcc will automatically be usable when you install g++ .
