doc: Improve windows build instructions using Linux subsystem
I did a build on a windows 10 laptop and took notes, and tried to improve the document: - It's the Linux subsystem for Windows, not the other way around. - Split out dependencies: general ones, 64-bit, 32-bit. Remove the reference to `build-unix.md`, easy enough to be self-contained. - Place 64-bit instructions first. 99% will want these. - Installation instructions: recommend using `/` for prefix, same as we do on gitian builds. This will allow copying the files to a usable (from Windows) place using just `make DESTDIR=...`. - Remove double spaces / consistent width reformatting.

With Windows 10, Microsoft has released a new feature named the

[Windows Subsystem for Linux](https://msdn.microsoft.com/commandline/wsl/about). This feature allows you to run a bash shell directly on Windows in an Ubuntu based

environment. Within this environment you can cross compile for Windows without the need for a separate Linux VM or Server.

installing the toolchain will be different.
|

|

Make sure you install the build requirements mentioned in
|

[build-unix.md](/doc/build-unix.md).
|
||||
Then, install the toolchains and curl:
|
||||
First, install the general dependencies:
|
||||
|
||||
sudo apt-get install g++-mingw-w64-i686 mingw-w64-i686-dev g++-mingw-w64-x86-64 mingw-w64-x86-64-dev curl

To build executables for Windows 32-bit:
|
||||
A host toolchain (`build-essential`) is necessary because some dependency
|
||||
packages (such as `protobuf`) need to build host utilities that are used in the
|

build process.
|

cd depends

|
||||
To build executables for Windows 64-bit, install the following dependencies:

||||
|
||||
sudo apt-get install g++-mingw-w64-x86-64 mingw-w64-x86-64-dev
|
||||

Installation
|
||||
-------------
|
||||
|
||||
After building using the Windows subsystem it can be useful to copy the compiled
|
||||
executables to a directory on the windows drive in the same directory structure
|
||||
as they appear in the release `.zip` archive. This can be done in the following
|
||||
way. This will install to `c:\workspace\bitcoin`, for example:
|
||||
|
||||
make install DESTDIR=/mnt/c/workspace/bitcoin
