How to install IQmol in Linux?

The IQmol is widely used to analyze the ouptut files form Q-Chem electronic structure theory code. In Windows, it is straight forward to install IQmol.exe package and it works fine.

However, in Linux distribution (Ubuntu 16.04), the .deb package can be installed just by downloading and opening in package installer. However, some functionalities are missing in installation.

Installation from the source.

I cloned the source code from GitHub.com/Iqmol and tried ./configure. I got following error.

./configure
