N.B. If you're interested in building Midipix using this script, please join the project's IRC channel #midipix on Freenode and ask for the address of the internal repositories required in order to build Midipix.
midipix[3] 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.
(reproduced from [3])
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.
Install the build-time dependencies listed in 2.1,
clone this repository, and run the following command line:
./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][5][5.1]
for the list of available build variables and how to override them.
N.B. Busybox is not supported.
Some packages (coreutils, grep, and tar, among others) override Alpine's BusyBox utilities of the same name, as the latter are either non-conformant or defective.
On successful completion of the build, a ZIP archive containing the Midipix
distribution will be created. Extract its contents on the target machine, run
bash.bat
, and then /install.sh
inside the resulting self-contained
Midipix installation shell window.
The following system requirements are assessed on build hosts equipped with the following hardware at minimum: * Intel(R) Xeon(R) CPU W3520 @ 2.67GHz (8 cores) * 7200 RPM SATA 3.1 HDD * 6 GB RAM
Target architecture | Build type | Distribution kinds selected | Average build time | Disk space required |
---|---|---|---|---|
nt64 | debug | minipix,rpm,zipdist | 2 hours | 57.60 GB |
nt64 | release | minipix,rpm,zipdist | 1 hours 45 minutes | 35.16 GB |
Package archive files and/or Git repositories additionally consume at least 1.70 GB.

Rebuild set of packages in isolation, along w/ their dependencies, if any, as needed, or forcibly, respectively:
./build.sh [ ... ] -r mc,zsh
./build.sh [ ... ] -r \*mc,zsh
./build.sh [ ... ] -r \*\*mc,zsh
Restart the configure
, build
, and install
steps of the coreutils
package.
./build.sh -r coreutils:configure,build,install
Rebuild entire build group:
./build.sh [ ... ] -r ALL native_runtime
usage: ./build.sh [-a nt32|nt64] [-b debug|release] [-C dir[,..]] [-D kind[,..]] [-F ipv4|ipv6|offline]
[-h] [-p jobs] [-P] [-r [*[*]]ALL|LAST|name[,..][:step,..]] [-R] [-v[v[v[v]]]]
[--as-needed] [--debug-minipix] [<group>[ ..]]
-a nt32|nt64 Selects 32-bit or 64-bit architecture; defaults to nt64.
-b debug|release Selects debug or release build; defaults to debug.
-C dir[,..] Clean build directory (build,) ${PREFIX} before processing build
scripts (prefix,) source directory (src,) and/or destination directory
(dest) after successful package builds.
-D kind[,..] Produce minimal midipix distribution directory (minipix,) RPM binary
packages (rpm,) and/or deployable distribution ZIP archive (zipdist.)
zipdist implies minipix.
-F ipv4|ipv6|offline
Force IPv4 (ipv4) or IPv6 (ipv6) when downloading package archives
and/or Git repositories or don't download either at all (offline.)
-h Show this screen.
-p jobs Enables parallelisation at group-level, whenever applicable.
-P The maximum count of jobs defaults to the number of logical
processors on the host system divided by two (2.)
If -R is not specified and at least one (1) package fails to build,
all remaining package builds will be forcibly aborted for convenience.
-r [*[*]]ALL[:step,..]|LAST|name[,..][:step,..]
Restart all packages/the specified comma-separated package(s)
completely or at optionally specified comma-separated step(s)
or restart the last failed package and resume build.
Prepend w/ `*' to automatically include dependencies and `**' to
forcibly rebuild all dependencies.
Currently defined steps are:
fetch_wget, fetch_git, fetch_extract,
configure_patch_pre, configure_autotools, configure_patch, configure,
build,
install_subdirs, install_make, install_files, install_libs, install, and install_rpm.
-R Ignore build failures, skip printing package logs, and continue
building (relaxed mode.)
-v[v[v[v]]] Be verbose; -vv: always print package logs; -vvv: set xtrace during package builds; -vvvv: logs fileops.
--as-needed Don't build unless the midipix_build repository has received new commits.
--debug-minipix Don't strip(1) minipix binaries to facilitate debugging minipix.
<group>[ ..] One of: host_deps, host_deps_rpm, host_toolchain, host_tools, minipix,
native_packages, native_runtime, native_toolchain, and/or native_tools.
The following variables are primarily defined in midipix.env
and may be
overriden on a per-build basis on the command-line after the last argument,
if any, e.g.:
./build.sh -a nt64 -b release -D minipix,zipdist -P -v PREFIX_ROOT="${HOME}/midipix_tmp"
Furthermore, ${HOME}/midipix_build.vars
, ${HOME}/.midipix_build.vars
,
and/or ../midipix_build.vars
are sourced during build initialisation and
may contain additional overrides, particularly ${DEFAULT_GITROOT_HEAD}
.

latter and/or in its corresponding file beneath vars/
. Additionally,
overrides may be specified on a per-build basis on the command-line after the
