Obtaining and installing a Midipix distribution

A Midipix distribution consists of the following: * the native Midipix toolchain, consisting of perk, gcc, its dependencies, and binutils, * musl, a lightweight, fast, simple, and free libc[1] used by Midipix, * the Midipix runtime components that bridge the gap between the libc and the executive subsystems of all Windows NT-derived Windows OS starting with and including Windows XP, and * a steadily increasing number of 3rd party open source packages, as expected in any modern POSIX-compliant *nix environment, including GNU coreutils, shells, libraries such as ncurses, libressl, as well as Perl and Python.

Compressed Midipix distribution tarballs and, separately, source tarballs are, at present, produced every four (4) hours UTC after each successful build and subsequently signed. This process is fully automated by a portable Bourne shell script; all of the above mentioned components are cross-compiled.

Thus, the most hassle-free way to get started with Midipix is to simply download the most recent distribution tarball and follow the instructions below. It is, however, recommended to anyone intending to use Midipix as a development platform to familiarise themselves with the build process. Other reasons to prefer building a Midipix distribution yourself include integrating new 3rd party software or local runtime component patches. At present, a full build from scratch takes about 30 (thirty) minutes to finish on an 8-core host with eight simultaneous make jobs, minus the generation of the tarballs. The build script can be obtained from the following GitHub repository: https://github.com/lalbornoz/midipix_build.

If you obtained a Midipix distribution tarball, extract it into a directory and drive of your choice, henceforth referred to as target directory; the drive can be a network drive. If you built Midipix yourself, the target directory is equivalent to the ${PREFIX} configured in build.vars, which defaults to ${HOME}/midipix.

Previously, this repository contained a shell script for usage within Cygwin and a VBS script in order to obtain a Midipix shell environment. These have been replaced with https://git.midipix.org/cgit.cgi/mpackage/plain/distro/bash.cmd from the Midipix distro skeleton[2]. In that respect, and as a general rule, midipix_build provides all the bits needed for (cross-)building the framework along with the entire collection of third-party software packages, whereas mpackage's task is to create a live execution environment (midipix-on-the-fly, or mxfly), optionally including with it a set of tarballs for the installation of a custom, midipix-based distribution.

Linux distribution-related errata

Busybox based distributions need the gawk, gsed, and coreutils packages to build perl.
