[Solved] autoscan: not found

If you are in process of compiling something on Ubuntu and you get error similar to these

./bootstrap.sh: 24: autoscan: not found

You have to install autoscan program but you can not find autoscan with

sudo aptitude search autoscan

The package name you have to install is autoconf. I don't know why because I'm not an expert on C/Linux but after below command, the compilation works.

sudo apt-get install autoconf
