Ubuntu 16.04 64-bit compatible with 32-bit programs in three steps

Step 1: Confirm the architecture of your system

dpkg --print-architecture
Output:
amd64
The result is amd64, which means the system is 64-bit.

Step 2: Confirm that multi-architecture support is enabled

dpkg --print-foreign-architectures
Output:
i386

If i386 is not output here, you need to enable multi-architecture support

sudo dpkg --add-architecture i386
sudo apt-get update

Step 3: Install the corresponding 32-bit library

sudo apt-get dist-upgrade (#This step is to update all software. If you don't need the new version of the software so urgently, you can skip it)
Or just install the related libraries sudo apt-get install lib32z1 lib32ncurses5 (some also require 32-bit stdc++ library lib32stdc++6-4.8-dbg)
Install gcc multilab
sudo apt-get install gcc-multilib g++-multilib
