                  Obtaining and installing a Midipix distribution
                   Last update: Sun, 24 Apr 2016 09:42:40 +0000

A Midipix distribution consists of the following:
a) the native Midipix toolchain, consisting of perk, gcc, its dependencies,
   and binutils,
b) musl, a lightweight, fast, simple, and free libc[1] used by Midipix,
c) 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
d) 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.

Compressed Midipix distribution tarballs and, separately, source tarballs are,
at present, produced every four (4) hours UTC after each successful build and
subsequently signed. This process is fully automated by a portable Bourne shell
script; all of the above mentioned components are cross-compiled.

Thus, the most hassle-free way to get started with Midipix is to simply download
the most recent distribution tarball and follow the instructions below. It is,
however, recommended to anyone intending to use Midipix as a development platform
to familiarise themselves with the build process. Other reasons to prefer building
a Midipix distribution yourself include integrating new 3rd party software or local
runtime component patches. At present, a full build from scratch takes about 30
(thirty) minutes to finish on an 8-core host with eight simultaneous make jobs,
minus the generation of the tarballs. The build script can be obtained from the
following GitHub repository: <https://github.com/lalbornoz/midipix_build>.

If you obtained a Midipix distribution tarball, extract it into a directory and
drive of your choice, henceforth referred to as target directory; the drive can
be a network drive. Do _not_ use anything but a true UNIX environment tar(1), as
e.g. WinRAR or WinZip handle extracting hard links incorrectly.
If you built Midipix yourself, the target directory is equivalent to the ${PREFIX}
configured in build.vars, which defaults to ${HOME}/midipix.

At present, providing an interactive Midipix environment still requires the Cygwin
terminal emulator Mintty and a shell; this does not include pseudoterminals, which
are entirely handled by Midipix. Both can be installed via the 64-bit Cygwin setup
program at <https://www.cygwin.com/setup-x86_64.exe>.

Once installed, launching a Midipix shell is accomplished by the `midipix.sh' shell
script provided in the target directory from within a Cygwin shell prompt in Mintty
and the target directory. This may either simply be done manually each time, or
automated by a shortcut. As shortcuts cannot be distributed, it can be created by
either:
a) Opening (executing) the VBScript script in the target directory from within the
   latter cscript.exe, providing the fully qualified pathname to Mintty, if it differs
   from the default value of C:\cygwin64\bin\mintty.exe or
b) manually creating a shortcut to Mintty with `Start in:' set to the target directory
   and the following command line:
   [ ... ]\mintty.exe -i /Cygwin-Terminal.ico -e sh midipix.sh, or

midipix alpha release: the final stretch
========================================

my.own.tasks@midipix.org
------------------------

* ofd tables: additional bucket allocation as needed.
* `ls -R //c`: check for the cause of individual failures.
  (might be related to the above ofd bucket allocation).
* integrate clone and the initial ldso implementation.
* integrate the signal queue, check signal implementation for
  semantic completion, especially in the context of multi-threaded
  applications.
* implement /dev/random and /dev/urandom, as well as other virtual
  folders needed by core applications.
* implement the scheduler functions.
* implement (possibly as stubs) missing system calls, fix existing
  system calls as needed by the core applications.
* toolchain: provided the few interfaces missing for C++ support.
* porting of mintty.


porting and other release-related tasks
---------------------------------------

* testing of ncurses.
* testing of bash and dash when built with ncurses.
* testing of all of the coreutils, seeing which ones fail due to
  a missing virtual file or folder, which ones fail due to a missing
  system call (crash), and which ones fail due to an incomplete or
  incorrect system call.
* porting of gdb.
