A software vendor distributing a 32-bit Linux application needs to compile it on their 64-bit development server. To link against ncurses for a text-based setup wizard, they need the 32-bit headers and libraries. lib32ncurses5-dev provides exactly that.

Use the modern equivalent: sudo apt-get install libncurses5-dev:i386 .

In newer distributions, ncurses version 5 is being phased out in favor of ncurses6 . Additionally, many systems now use a more flexible multi-arch approach where you install the standard development package with a specific architecture suffix (e.g., libncurses5-dev:i386 ) rather than a dedicated lib32 package.
