Error installing htk-tool

When I try to compile and install HTK, it produces the following error:

HTK is now ready to be built.

Type "make all" to build the HTK libraries
and tools.

Then "make install" to install them.

The tools will be installed in /usr/local/bin

Build notes: Language Modelling tools will be
built. HDecode will not be built. You can build
it manually later by running 'make hdecode
install-hdecode'

Several pitfalls when building HTK with e.g. Ubuntu 16.04 - amd64. a) The new path´s. b) HTK is built with gcc -m32 : i386 build prerequisites are required. Much easier if CentOS 6.9 - i386 or CentOS 7 - x86_64.

The package htk-tools_3.4.1-ubuntu14_i386.deb was created on Ubuntu 14.04 - i386, the files are from a HTK-3.4.1 build with CentOS 7.

Ubuntu 16.04 - amd64 : Download, and install :

cd Downloads/
sudo gdebi htk-tools_3.4.1-ubuntu14_i386.deb
            // some 32bits dependencies will be installed too
