Building a mingw-w64 GCC cross-compiler with nixcrpkgs: instructions for Terry, October 2018

Install Nix, the functional package manager. You'll need Linux (but macOS might work too).
Make sure you have at least 4 GB of free space available for /tmp and a few GB of free space available for /nix.
To get my recipes, run: git clone https://github.com/DavidEGrayson/nixcrpkgs && cd nixcrpkgs && git checkout 4f7b11d That commit is the current tip of the dev/david/2019 branch.
To build a i686-w64-mingw32 C/C++ cross-compiling toolchain and a hello world program, run: nix-build -A win32.hello
To build Qt and its examples, run: nix-build -A win32.qt.examples
To just build the toolchain itself, run: nix-build -A win32.gcc

Attention: After following all the steps run gdk-pixbuf-query-loaders --update-cache as root, this prevents various gdk-related bugs that have been reported in the last few hours. Symptoms are varied, and for Cinnamon the DE fails to start entirely while for XFCE the icon theme seemingly can't be changed anymore etc.

Check the gist's comments for any further tips and instructions, especially if you are running into problems!
