The g++ and gcc are installed.

Answer 1

If you are using Ubuntu linux (derivative) Install:

sudo apt-get install gfortan-7 libblas-dev liblapack-dev

I might suggest also checking:

gcc --version
g++ --version

To make sure you have these installed as well.

One rant: The error messages for installing igraph are horrid.
