This is a Red/System Termbox wrapper. I've only tested it on Linux (elementary OS). Red is currently 32-bit only so you need to build a 32-bit shared Termbox library.

tb-blit and tb-cell-buffer functions are currently disabled.

Installation

On Debian based Linux distros the 32-bit shared Termbox library can be built with something like this:

sudo apt install gcc-5-multilib
CFLAGS=-m32 LDFLAGS=-m32 ./waf configure --prefix=/usr
./waf

Copy the termbox.reds file into your project folder and use it that way. Install the shared library via waf or simply copy it next to your source files.

Example: In this repository I've just copied the .so into the examples folder as I had issues installing the 32-bit version next to the existing 64-bit one.
