How to solve LT_INIT command not found on Linux

Problem:

You are running a configure script on Linux. It exits with a message like this:

./configure: line 3638: LT_INIT: command not found

Solution

You’re missing GNU libtool. Install it using your distribution’s package manager, for example on Ubuntu use

sudo apt-get install libtool

LT_INIT in the error message means libtool init, but unfortunately autoconf & automake don’t seem to recognize a missing libtool in all cases.
