Building a midipix distribution
Common tasks
Fault-tolerant & highly optimised 3D laser show-equipped usage screen
Non-exhaustive list of build variables
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
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.
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}.
| 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 |

The following variables are package-specific and receive their value from either
top-level defaults defined in midipix.env, build group-specific defaults from
the build group the package pertains to and defined in its corresponding file beneath
groups/, or package-specific overrides defined either in the 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 last argument, with each variable
prefixed w/ PKG_, e.g.: ./build.sh [ ... ] PKG_ZSH_CC="/bin/false".
The minimum set of package variables that must be provided is SHA256SUM, URL, VERSION
and URLS_GIT, respectively.
