In the old days you just installed ia32-libs.

Nowadays you do something like this:

    $ sudo apt-get install lib32z1 lib32ncurses5
    $ sudo apt-get install gcc-multilib gcc-7-multilib
    $ sudo apt-get install g++-multilib g++-7-multilib

You should check the version of GCC that comes with the platform and
use the specific version when installing. My -m32 test system happens
to use GCC 7 by default, hence gcc-7-multilib and g++-7-multilib.

If you have dependencies, then you use the <package>:i386 syntax, like:

    $ sudo apt-get install libfoo:i386
