You need the g++ compiler, not gcc, so install the
g++ package, and maybe
build-essential for any needed headers:
sudo apt-get install g++
And if necessary (probably not for this package):
sudo apt-get install build-essential
You should read the README file(s), then the INSTALL file and follow the instructions. They usually boil down to running configure:
Then running make:
Then, if you want to install the programs in a system area, run:
sudo make install
The configure step should search out the necessary parts (g++) and complain and stop if necessary parts are not found. It builds the Makefile from the information about your system.
I had no issues with the downloaded package, but then again, I do have the
build-essential package installed for what I do.
g++ gets installed into
/usr/bin, which should be a normal part of your
