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.

N.B. If in doubt, consult the fault-tolerant & highly optimised 3D laser show-equipped usage screen w/ ./build.sh -h or a hungry lion might eat you alive.

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] 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 below, clone this repository, and run the following command line within the latter:

./build.sh -a nt64 -b release -D minipix,zipdist -P -v

Build-time dependencies

  • Alpine Linux: binutils bzip2 cmake coreutils curl findutils g++ gawk gcc git grep gzip libc-dev linux-headers lzip make musl-dev net-tools patch perl perl-xml-parser procps sed tar util-linux wget xz zip
  • Debian/-derived Linux: binutils bzip2 clzip cmake coreutils curl findutils g++ gawk gcc git grep gzip hostname libc6-dev libxml-parser-perl lzma make patch perl procps sed tar util-linux wget xz-utils zip
  • OpenSUSE Linux: binutils bzip2 cmake coreutils curl findutils gawk gcc gcc-c++ git grep gzip hostname linux-glibc-devel lzip make patch perl perl-XML-Parser procps sed tar util-linux wget xz zip

N.B. Busybox is not supported.

N.B. 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.

Non-exhaustive list of build variables

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}.

Variable name Default value Description
ARCH nt64 Target 32-bit (nt32) or 64-bit (nt64) architecture
BUILD debug Build w/ debugging (debug) or release compiler flags
BUILD_DLCACHEDIR ${PREFIX_ROOT}/dlcache Absolute pathname to package downloads cache root directory
BUILD_WORKDIR ${PREFIX}/tmp Absolute pathname to temporary package build root directory
PREFIX ${PREFIX_ROOT}/${ARCH}/${BUILD} Absolute pathname to architecture- & build type-specific build root directory
PREFIX_CROSS ${PREFIX}/${DEFAULT_TARGET} Absolute pathname to toolchain root directory
PREFIX_MINGW32 ${PREFIX}/x86_64-w64-mingw32 Absolute pathname to MinGW toolchain root directory
PREFIX_MINIPIX ${PREFIX}/minipix Absolute pathname to minipix distribution root directory
PREFIX_NATIVE ${PREFIX}/native Absolute pathname to cross-compiled packages root directory
PREFIX_ROOT ${HOME}/midipix Absolute pathname to top-level directory
PREFIX_RPM ${PREFIX}/rpm Absolute pathname to package RPM archive root directory

Common tasks

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

Rebuild entire build group:

./build.sh [ ... ] -r ALL native_runtime
