## 1. What is midipix, and how is it different?
Lucio Andrés Illanes Albornoz 531158

Lucio Andrés Illanes Albornoz 531158
midipix is a development environment that lets you create programs
Lucio Andrés Illanes Albornoz 531158
for Windows using the standard C and POSIX APIs. No compromises made,
Lucio Andrés Illanes Albornoz 531158
no shortcuts taken.  
Lucio Andrés Illanes Albornoz 531158
  
Lucio Andrés Illanes Albornoz 531158
If you are interested in cross-platform programming that reclaims
Lucio Andrés Illanes Albornoz 531158
the notion of write once, compile everywhere; if you believe that the
Lucio Andrés Illanes Albornoz 531158
'standard' in the C Standard Library should not be a null signifier;
Lucio Andrés Illanes Albornoz 531158
and if you like cooking your code without #ifdef hell and low-level
Lucio Andrés Illanes Albornoz 531158
minutiae, then this page is for you.  
Lucio Andrés Illanes Albornoz 531158
  
Lucio Andrés Illanes Albornoz 531158
midipix makes cross-platform programming better, simpler and faster,
Lucio Andrés Illanes Albornoz 531158
specifically by bringing a modern, conforming C Runtime Library to the
Lucio Andrés Illanes Albornoz 531158
Windows platform. While the idea itself is not new, the approach taken
Lucio Andrés Illanes Albornoz 531158
in midipix to code portability is radically different from that found
Lucio Andrés Illanes Albornoz 531158
in other projects.

### 2.1. Building, installing and using a midipix distribution
Lucio Andrés Illanes Albornoz 531158

Lucio Andrés Illanes Albornoz 531158
A Midipix distribution consists of the following:
Lucio Andrés Illanes Albornoz 531158
* the native Midipix toolchain, consisting of perk, gcc, its dependencies,
Lucio Andrés Illanes Albornoz 531158
  and binutils,
Lucio Andrés Illanes Albornoz 531158
* musl, a lightweight, fast, simple, and free libc[[1](https://www.musl-libc.org/faq.html)] used by Midipix,
Lucio Andrés Illanes Albornoz 531158
* the Midipix runtime components that bridge the gap between the libc and the
Lucio Andrés Illanes Albornoz 531158
  executive subsystems of all Windows NT-derived Windows OS starting with and
Lucio Andrés Illanes Albornoz 531158
  including Windows XP, and
Lucio Andrés Illanes Albornoz 531158
* a steadily increasing number of 3rd party open source packages, as expected in
Lucio Andrés Illanes Albornoz 531158
  any modern POSIX-compliant \*nix environment, including GNU coreutils, shells,
Lucio Andrés Illanes Albornoz 531158
  libraries such as ncurses, libressl, as well as Perl and Python.
Lucio Andrés Illanes Albornoz 531158

Lucio Andrés Illanes Albornoz 531158
Install the build-time dependencies listed in section [2.1.1](#211-build-time-dependencies),
Lucio Andrés Illanes Albornoz 531158
clone this repository (e.g. ``git clone https://dev.midipix.org/build/midipix_build``)
Lucio Andrés Illanes Albornoz 531158
and run the following command line:
Lucio Andrés Illanes Albornoz 531158

Lucio Andrés Illanes Albornoz 531158
```shell
Lucio Andrés Illanes Albornoz 531158
./build.sh -a nt64 -b release -D zipdist -P -v
Lucio Andrés Illanes Albornoz 531158
```
Lucio Andrés Illanes Albornoz 531158

Lucio Andrés Illanes Albornoz 531158
By default, the build will take place within ``${HOME}/midipix/nt64/release``
Lucio Andrés Illanes Albornoz 531158
and package archive files and/or Git repositores will be downloaded into
Lucio Andrés Illanes Albornoz 531158
``${HOME}/midipix/dlcache``. Consult sections [4.2](#42-build-variables) and
Lucio Andrés Illanes Albornoz 531158
[4.5](#45-package-variables) for the list of available build/package variables
Lucio Andrés Illanes Albornoz 531158
and how to override them.  
Lucio Andrés Illanes Albornoz 531158
Parallelisation is enabled by the above command line for both packages that can
Lucio Andrés Illanes Albornoz 531158
be built independently of each other and ``make(1)`` via ``-j``, limited to the
Lucio Andrés Illanes Albornoz 531158
amount of logical processors on the build host divided by two (2).

Lucio Andrés Illanes Albornoz 531158
  
Lucio Andrés Illanes Albornoz 531158
> N.B. The pathname of the target directory containing ``bash.bat`` and all other

### 2.4. Troubleshooting
Lucio Andrés Illanes Albornoz 531158

Lucio Andrés Illanes Albornoz 531158
Midipix presently provides, inter alia, strace-like functionality via
Lucio Andrés Illanes Albornoz 531158
ntctty's logging capabilities. This is available both through the regular
Lucio Andrés Illanes Albornoz 531158
``strace(1)`` command as distributed, which however **must** be provided
Lucio Andrés Illanes Albornoz 531158
with an absolute pathname without consideration for ``${PATH}``, as well
Lucio Andrés Illanes Albornoz 531158
as directly via ``ntctty.exe`` for a session by running ``ntctty.exe``
Lucio Andrés Illanes Albornoz 531158
with the ``--log-level 7`` option, e.g.:
Lucio Andrés Illanes Albornoz 531158

Lucio Andrés Illanes Albornoz 531158
```shell
Lucio Andrés Illanes Albornoz 531158
$ #strace ls -la /        # (incorrect, relative pathname)
Lucio Andrés Illanes Albornoz 531158
$ strace /bin/ls -la /    # (correct, absolute pathname)
Lucio Andrés Illanes Albornoz 531158
$ ntctty.exe --log-level 7 -e /bin/ls -la /
Lucio Andrés Illanes Albornoz 531158
$ ntctty.exe --log-level=7 -e /bin/ls -la /
Lucio Andrés Illanes Albornoz 531158
$ ntctty.exe --log-level 7 -e /bin/sh -c "ls -la /"
Lucio Andrés Illanes Albornoz 531158
$ ntctty.exe --log-level=7 -e /bin/sh -c "ls -la /"
Lucio Andrés Illanes Albornoz 531158
```
Lucio Andrés Illanes Albornoz 531158

Lucio Andrés Illanes Albornoz 531158
By default, ``ntctty.exe`` log files are written into the /var/log/ntctty
Lucio Andrés Illanes Albornoz 531158
directory; this may be adjusted with the ``--log-dir`` and/or
Lucio Andrés Illanes Albornoz 531158
``--log-file`` options. ``strace(1)`` logs to stderr by default.

## 3.2. Adding a package
Lucio Andrés Illanes Albornoz 531158

Lucio Andrés Illanes Albornoz 531158
Packages are grouped into *build groups* according to sets of common package
Lucio Andrés Illanes Albornoz 531158
variable defaults, such as ``${PKG_CFLAGS_CONFIGURE}, ${PKG_LDFLAGS_CONFIGURE}``
Lucio Andrés Illanes Albornoz 531158
and ``${PKG_CONFIGURE_ARGS}``, and semantic interrelatedness, such as the
Lucio Andrés Illanes Albornoz 531158
``native_runtime`` build group comprising the Midipix runtime components.
Lucio Andrés Illanes Albornoz 531158
Packages may belong to more than one build group such as when subsumed by a shorthand
Lucio Andrés Illanes Albornoz 531158
build group e.g. the ``dev_packages`` build group, as long as the default set of build
Lucio Andrés Illanes Albornoz 531158
groups or as overriden on the command line does not entail group membership conflicts.  
Lucio Andrés Illanes Albornoz 531158
  
Lucio Andrés Illanes Albornoz 531158
Build groups files beneath ``groups/`` named ``[0-9][0-9][0-9].<group name>.group``
Lucio Andrés Illanes Albornoz 531158
contain package variable defaults, the alphabetically sorted list of contained
Lucio Andrés Illanes Albornoz 531158
packages in ``<upper case group name>_PACKAGES``, and their package variables
Lucio Andrés Illanes Albornoz 531158
sorted alphabetically with the exception of ``${PKG_DEPENDS}`` (if present,)
Lucio Andrés Illanes Albornoz 531158
``${PKG_SHA256SUM}``, ``${PKG_URL}``, and ``${PKG_VERSION}``, and/or ``${PKG_URLS_GIT}``,
Lucio Andrés Illanes Albornoz 531158
which are specified in this order.  
Lucio Andrés Illanes Albornoz 531158
  
Lucio Andrés Illanes Albornoz 531158
Pick a build group according to the criteria mentioned, add the package to the
Lucio Andrés Illanes Albornoz 531158
build group's list of contained packages in its corresponding file, and add the
Lucio Andrés Illanes Albornoz 531158
set of package variables required (see above and section [4.5](#45-package-variables).)  
Lucio Andrés Illanes Albornoz 531158
Consult section [3.7](#37-patches-and-vars-files) if the package to be added
Lucio Andrés Illanes Albornoz 531158
requires patches or additional code amending or replacing package build steps
Lucio Andrés Illanes Albornoz 531158
or the entire package build. Consult section [4.1](#41-build-steps) for a list
Lucio Andrés Illanes Albornoz 531158
of package build steps and how they are overriden.

## 3.3. Addressing build failure
Lucio Andrés Illanes Albornoz 531158

Lucio Andrés Illanes Albornoz 531158
During package build, standard error and output are redirected into a log file beneath
Lucio Andrés Illanes Albornoz 531158
``${BUILD_WORKDIR}`` named ``${PKG_NAME}_stderrout.log``, following a package variable
Lucio Andrés Illanes Albornoz 531158
dump. If ``-vv`` was specified, package logs will additionally be printed to standard
Lucio Andrés Illanes Albornoz 531158
output. If ``-vvv`` was specified, ``xtrace`` will be set during package builds for
Lucio Andrés Illanes Albornoz 531158
rudimentary debugging purposes. Additionally, packages using GNU autotools will, if
Lucio Andrés Illanes Albornoz 531158
package configuration failed or appears relevant, log the configuration process in detail
Lucio Andrés Illanes Albornoz 531158
in, most usually, ``${PKG_BUILD_DIR}/config.log``.  
Lucio Andrés Illanes Albornoz 531158

Lucio Andrés Illanes Albornoz 531158
If ``--dump-on-abort`` was specified, a subset of the variables set and environment
Lucio Andrés Illanes Albornoz 531158
variables exported will be written to ``${BUILD_WORKDIR}/${PKG_NAME}.dump``, which may
Lucio Andrés Illanes Albornoz 531158

### 3.6. Package-package and {package,group}-group relationships
Lucio Andrés Illanes Albornoz 531158

Lucio Andrés Illanes Albornoz 531158
Packages, as well as groups, are interrelated through implicit as well as explicit parametrised,

typed relationships and form namespaces correspondingly.  
Lucio Andrés Illanes Albornoz 531158
  
Lucio Andrés Illanes Albornoz 531158
These primarily, by expressing modalities of constraining, derivation, and/or subdividision, govern
Lucio Andrés Illanes Albornoz 531158
the build and mirroring, etc. processes with regard to ordering constraints (e.g. ``depends``)
Lucio Andrés Illanes Albornoz 531158
and derivation or sharing of sets of variables and/or patches and/or ``vars/`` files (e.g.
Lucio Andrés Illanes Albornoz 531158
``group``, ``flavour``, ``inherit``) or build and/or source directories (e.g. ``module``,) etc.  
Lucio Andrés Illanes Albornoz 531158
They may, however, also be subject to enquiry for descriptive, diagnostic, or visualising purposes,
Lucio Andrés Illanes Albornoz 531158
particularly as concerns the namespaces they form.

top-level defaults defined in ``midipix.env``, build group-specific defaults from the
Lucio Andrés Illanes Albornoz 531158
build group the package pertains to and defined in its corresponding file beneath
Lucio Andrés Illanes Albornoz 531158
``groups/``, or package-specific overrides defined either in the latter and/or in its
Lucio Andrés Illanes Albornoz 531158
corresponding file beneath ``vars/``, with one of the following prefixes:
Lucio Andrés Illanes Albornoz 531158
