+#===============================================================
+# Filename : macsimum
+# Purpose : Builds Mac-to-Linux cross-compiler toolchains.
+# Authors : Zach van Rijn <me@zv.io>
+# License : MIT
+# Revision : 20200303
+#===============================================================
+
+#---------------------------------------------------------------
+# README
+#
+# overview
+# --------
+#
+# This script builds "musl-cross-make" cross-compiler toolchains
+# that are hosted on macOS and target Linux. For example, your
+# Macintosh machine can use up-to-date versions of GCC to build
+# code (C, C++, Fortran) for your MIPS router. The libc used is
+# called 'musl': https://www.musl-libc.org/faq.html
+#
+# Others have tried and failed to deliver what you're able to do
+# with this tiny script.
+#
+# What does this look like? Modern GCC that does:
+#
+# * macOS --> ARM, Motorola 68000, MIPS, OpenRISC, PowerPC,
+# RISC-V, S/390, SuperH, x86-based, more?
+#
+# The goal, of course, is to achieve parity with musl.cc's Linux
+# offerings. A link to pre-built macOS binaries is now public,
+# and this is the script to reproduce them. https://mac.musl.cc/
+#
+#
+# requirements
+# ------------
+#
+# Basically, you need XCode Command Line Tools. I don't know any
+# specific version requirements, but if you encounter problems I
+# would appreciate a heads up.
+#
+# This document may be useful: https://git.zv.io/snippets/34/raw
+#
+# You'll also need a working internet connection.
+#
+# A previous version of this script relied on Homebrew for some
+# of the utilities that we're using. This, contrary to intent,
+# created a Homebrew dependency. No longer! Build products are
+# now fully portable (across compatible macOS / OS X versions).

+# Build configuration
+
+##
+# It is possible to build all library and utility dependencies
+# for the building of musl-cross-make production toolchains on a
+# RAM disk. This may improve performance on systems with slow
+# disks, and requires approximately 3GB of space. 4GB is safe:
+#
+# $ diskutil erasevolume HFS+ "RAMDISK" \
+# `hdiutil attach -nomount ram://$((2048 * 1024 * 4))`
+#
+# The '4' in the above example represents gigabytes.
+
+rdsk=/Volumes/RAMDISK; # dependency build prefix
+
+##
+# When the production toolchains are built, a significant bit of
+# disk space is required. Do not attempt to build them in RAM if
+# you are not on a server server with several dozen gigabytes of
+# RAM and the assurance that your system won't crash :)
+
+bdsk=/tmp; # production build prefix
+
+##
+# This directory will contain dependency build trees. It can be
+# deleted after the toolchains are built.
+
+bdir=${rdsk}/tmp; # scratch directory location
+
+##
+# Within each dependency build tree, we want to perform an out-
+# of-tree build. This is the (arbitrary) name of that directory.
+
+tdir=x; # out-of-tree directory name
+
+##
+# This directory will contain the dependency libraries and tools
+# and can also be deleted after the toolchains are built, but it
+# may be useful to maintain this directory for future builds.

+#===============================================================
+# Filename : scripts/sinner
+# Purpose : Builds Linux-to-Windows cross-compiler toolchains.

+# Revision : 20190531

+# README
+#
+# overview
+# --------
+#
+# This script builds "musl-cross-make" cross-compiler toolchains
+# that are hosted on Linux and target Windows. For example, your
+# MIPS router can use up-to-date versions of GCC to build code
+# (C, C++, Fortran) for your Windows XP machine. The libc used
+# is called 'musl': https://www.musl-libc.org/faq.html
+#
+# Others have tried and failed to deliver what you're able to do
+# with this tiny script. Additions to this list are welcome:
+#
+# What does this look like? Modern GCC that does:
+#
+# * Linux on ARM, Motorola 68000, MIPS, OpenRISC, PowerPC,
+# RISC-V, S/390, SuperH, x86-based, more?
+#
+# --> Windows XP to 10, and possibly older.
+#
+# The goal, of course, is to achieve parity with musl.cc's Linux
+# offerings. This is the script to build the binaries located at
+# https://more.musl.cc/YOUR-HOST-ARCHITECTURE/*-w64-mingw32.zip
+#
+#
+# build platforms
+# ---------------
+#
+# You need Linux to build these, and an architecture that runs a
+# toolchain from musl.cc.
+#
+#
+# requirements
+# ------------
+#
+# Consider running this script inside of an isolated environment
+# such as a container or virtual machine. While not required, we
+# do not recommend running any foreign scripts or binaries in an
+# important environment. You'll need the following packages:
+#
+# * cmake
+# * curl
+# * git
+# * make
+# * patch (GNU)
+# * tar
+# * xz
+# * zip
+#
+# e.g., apk add cmake curl git make patch rsync tar xz zip
+#
+#
+# other notes
+# -----------
+#
+# * A prior version of this script ('prepare') relies on Linux
+# 'binfmt_misc' and QEMU to emulate certain build byproducts
+# and requires root privileges to install (but not use) that
+# setup. This version cross-compiles the toolchains purely.
+#
+# * This script uses the 'mingw-cross-make' flavor maintained
+# at https://git.zv.io/toolchains/mingw-cross-make to build
+# MinGW toolchains. Issues should be addressed there.

+# not necessarily correspond to what is built here (yet, TODO).

+
+## Directories
+#
+# By default, all toolchains that can be built, are built. This
+# requires a significant amount of disk space. Please ensure you
+# have at least 50GB of free disk space in these directories:
+#
+base="${HOME}/sinner_src" # base source directory
+huge="${HOME}/sinner_bld" # base build directory
+logs="${HOME}/sinner_log" # suite build log directory
+zips="${HOME}/sinner_bin" # completed toolchains go here
+
+## Toolchain Mirror
+#
+# If you have access to an x86_64 Linux machine, or one that has
+# an x86_64 QEMU user-mode emulator registered in 'binfmt_misc',
+# you will always be using the latest available software.
+#
+musl=https://more.musl.cc # more.musl.cc or mirror
+
+## Toolchain Naming Conventions
+#
+# The musl.cc toolchains follow a simple naming convention: all
+# cross compilers are suffixed with '-cross', native '-native'.
+# If you're using a different mirror or convention, set it here.
+#
+csuf=-cross # cross suffix
+nsuf=-native # native suffix
+
+## Toolchain Tuples
+#
+# Values can be found at 'https://more.musl.cc/' where the $user
+# variable corresponds to your build platform, and $host to your
+# intended Linux development environment. Note that unless the
+# website says otherwise, only the 'x86_64-linux-musl' toolchain
+# directory is up-to-date. If you can't find what you're looking
+# for you must build a MinGW-w64 suitable toolchain from source.
+#

+## Build Environment
+#
+# This variable is extended during the toolchain download step.

+## Repositories
+#
+# The build infrastructure used is called "musl-cross-make" and
+# is upstream https://github.com/richfelker/musl-cross-make, but
+# this version is incompatible with the current script. It's out
+# of date, too, so please leave the default unless you fork it.

+# README
+#
+# overview
+# --------
+#
+# This script builds "musl-cross-make" cross-compiler toolchains
+# that are hosted on Windows and target Linux. For example, your
+# Windows XP machine can use up-to-date versions of GCC to build
+# code (C, C++, Fortran) for your MIPS router. The libc used is

+# Others have tried and failed to deliver what you're able to do

+#
+# * https://gnutoolchains.com/download/
+# * (um?)
+#
+# What does this look like? Modern GCC that does:
+#
+# * Win32 --> ARM, Motorola 68000, MIPS, OpenRISC, PowerPC,
+# RISC-V, S/390, SuperH, x86-based, more?
+#
+# The goal, of course, is to achieve parity with musl.cc's Linux
+# offerings. A link to pre-built Windows binaries is now public,
+# and this is the script to reproduce them. https://win.musl.cc/
+#
+#
+# build platforms
+# ---------------
+#
+# In absolute theory, one can build this toolchain suite using a
+# "native" toolchain from 'musl.cc' suitable for your platform,
+# to build a MinGW-w64 cross-compiler (hosted on your platform,
+# targeting i686- or x86_64- Windows), then use that toolchain
+# to build the suite. Some may exist here: https://more.musl.cc/
+#
+# In practice, you just need 'i686-w64-mingw32-cross' for 32-bit
+# or 'x86_64-w64-mingw32-cross' for 64-bit that runs on your own
+# Linux (or Windows, with Cygwin or MSYS2) system.
+#
+#
+# requirements
+# ------------
+#
+# Consider running this script inside of an isolated environment
+# such as a container or virtual machine. While not required, we
+# do not recommend running any foreign scripts or binaries in an
+# important environment. You'll need the following packages:
+#
+# * cmake
+# * curl
+# * git
+# * make
+# * patch (GNU)
+# * rsync
+# * tar
+# * xz
+# * zip
+#
+# e.g., apk add cmake curl git make patch rsync tar xz zip
+#
+# You'll also need an internet connection (or manually do so) to
+# obtain corresponding "donor" toolchains from musl.cc; what we
+# are doing is pulling musl and the Linux kernel headers from an
+# existing toolchain, rather than fuss with getting them to play
+# nicely with the "Canadian" cross infrastructure.
+#
+#
+# other notes
+# -----------
+#
+# * Toolchains cannot be built with kernel headers; these are
+# copied into the output directory after the initial build.
+# Kernel version is that of donor toolchain.
+#
+# * Toolchains cannot be built with the musl library; this is
+# copied into the output directory after the initial build.
+# musl version is that of donor toolchain, but may be flaky.
+#
+# * If you do not uncomment the 'nano' line, you will build a
+# large number of toolchains. This requires an exceptional
+# amount of disk space and time. This is what I use it for.
+#
+#
+# to-do
+# -----
+#
+# * Fix underlying issue causing kernel headers and musl to be
+# not built or installed correctly.
+#
+# * Generate Cygwin (and/or MSYS2) packages for distribution.
