fennel-static-readline

This repo is an example of how to create a statically linked binary that includes readline. It uses an alpine docker image which install static versions of readline and ncurses, build a static version of the lua-readline bindins, then uses those to build a static binary.

The following libraries are used from Alpine packages:

• /usr/lib/libreadline.a from readline-static
• /usr/lib/libhistory.a from readline-static
• /usr/lib/libncursesw.a from ncurses-static

Prerequisites

• git
• make
• docker

Building

To build the static binary, run make fennel-static-readline in the root of this repo. (This is also the default make target, so just running make on its own will have the same effect.)

To get a gzipped version of the binary, run make fennel-static-readline.gz.

How big is it?

All the following numbers are based on the results I got on my machine. These sizes will be output to the sizes directory each time the relevant make targets are built.

• Before running strip, the binary is 1.6M. (see sizes/initial.txt)
• After running strip, it shrinks to 720K. (see sizes/stripped.txt)
• After gzipping, it shrinks to 316K. (see sizes/gzipped.txt)
