midipix[\[3](#r3)] is a development environment that lets you create programs for
Windows using the standard C and POSIX APIs. No compromises made, no shortcuts
taken.
If you are interested in cross-platform programming that reclaims the notion of
write once, compile everywhere; if you believe that the 'standard' in the C
Standard Library should not be a null signifier; and if you like cooking your
code without #ifdef hell and low-level minutiae, then this page is for you.
midipix makes cross-platform programming better, simpler and faster,
specifically by bringing a modern, conforming C Runtime Library to the Windows
platform. While the idea itself is not new, the approach taken in midipix to
code portability is radically different from that found in other projects.

## 2. Building 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](#r1)] 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.
Install the build-time dependencies listed in [2.1](#2-1-build-time-dependencies),
clone this repository, and run the following command line:
```shell
./build.sh -a nt64 -b release -D minipix,zipdist -P -v
```
By default, the build will take place within ``${HOME}/midipix/nt64/release``
and package archive files and/or Git repositores will be downloaded into
``${HOME}/midipix/dlcache``. Consult [\[3.1](#3-1-fault-tolerant--highly-optimised-3d-laser-show-equipped-usage-screen)][\[5](#5-build-variables)][\[5.1](#5-1-package-variables)]
for the list of available build variables and how to override them.

On successful completion of the build, a ZIP archive containing the Midipix

``bash.bat``, and then ``/install.sh`` inside the resulting self-contained
Midipix installation shell window.

* Intel(R) Xeon(R) CPU W3520 @ 2.67GHz (8 cores)
* 7200 RPM SATA 3.1 HDD
* 6 GB RAM
