If you’ve tried to install OFSoftswitch13, maybe you have faced with the problem: “c++ compiler cannot create executables” at ./configure stage even though you have installed the OFSoftswitch13 dependencies:
$ sudo apt-get install cmake libpcap-dev libxerces-c2-dev libpcre3-dev flex bison pkg-config autoconf libtool libboost-dev
The problem is because you probably did not have installed build-essential package. So, all you have to do, is to install it.
$ sudo apt-get install build-essential
