4 Below are some notes on how to build Bitcoin Core for Windows.
6 Most developers use cross-compilation from Ubuntu to build executables for
7 Windows. This is also used to build the release binaries.
9 Currently only building on Ubuntu Trusty 14.04 is supported.
10 Other versions are unsupported or known to be broken (e.g. Ubuntu Xenial 16.04).
12 While there are potentially a number of ways to build on Windows (for example using msys / mingw-w64),
13 using the Windows Subsystem For Linux is the most straightforward. If you are building with
14 another method, please contribute the instructions here for others who are running versions
15 of Windows that are not compatible with the Windows Subsystem for Linux.
17 Compiling with Windows Subsystem For Linux
18 -------------------------------------------
20 With Windows 10, Microsoft has released a new feature named the [Windows
21 Subsystem for Linux](https://msdn.microsoft.com/commandline/wsl/about). This
22 feature allows you to run a bash shell directly on Windows in an Ubuntu-based
23 environment. Within this environment you can cross compile for Windows without
24 the need for a separate Linux VM or server.
26 This feature is not supported in versions of Windows prior to Windows 10 or on
27 Windows Server SKUs. In addition, it is available [only for 64-bit versions of
28 Windows](https://msdn.microsoft.com/en-us/commandline/wsl/install_guide).
30 To get the bash shell, you must first activate the feature in Windows.
32 1. Turn on Developer Mode
33 * Open Settings -> Update and Security -> For developers
34 * Select the Developer Mode radio button
35 * Restart if necessary
36 2. Enable the Windows Subsystem for Linux feature
37 * From Start, search for "Turn Windows features on or off" (type 'turn')
38 * Select Windows Subsystem for Linux (beta)
40 * Restart if necessary
41 3. Complete Installation
42 * Open a cmd prompt and type "bash"
44 * Create a new UNIX user account (this is a separate account from your Windows account)
46 After the bash shell is active, you can follow the instructions below, starting
47 with the "Cross-compilation" section. Compiling the 64-bit version is
48 recommended but it is possible to compile the 32-bit version.
53 These steps can be performed on, for example, an Ubuntu VM. The depends system
54 will also work on other Linux distributions, however the commands for
55 installing the toolchain will be different.
57 First, install the general dependencies:
59 sudo apt-get install build-essential libtool autotools-dev automake pkg-config bsdmainutils curl
61 A host toolchain (`build-essential`) is necessary because some dependency
62 packages (such as `protobuf`) need to build host utilities that are used in the
65 See also: [dependencies.md](dependencies.md).
67 ## Building for 64-bit Windows
69 To build executables for Windows 64-bit, install the following dependencies:
71 sudo apt-get install g++-mingw-w64-x86-64 mingw-w64-x86-64-dev
75 PATH=$(echo "$PATH" | sed -e 's/:\/mnt.*//g') # strip out problematic Windows %PATH% imported var
77 make HOST=x86_64-w64-mingw32
79 ./autogen.sh # not required when building from tarball
80 CONFIG_SITE=$PWD/depends/x86_64-w64-mingw32/share/config.site ./configure --prefix=/
83 ## Building for 32-bit Windows
85 To build executables for Windows 32-bit, install the following dependencies:
87 sudo apt-get install g++-mingw-w64-i686 mingw-w64-i686-dev
91 PATH=$(echo "$PATH" | sed -e 's/:\/mnt.*//g') # strip out problematic Windows %PATH% imported var
93 make HOST=i686-w64-mingw32
95 ./autogen.sh # not required when building from tarball
96 CONFIG_SITE=$PWD/depends/i686-w64-mingw32/share/config.site ./configure --prefix=/
101 For further documentation on the depends system see [README.md](../depends/README.md) in the depends directory.
106 After building using the Windows subsystem it can be useful to copy the compiled
107 executables to a directory on the windows drive in the same directory structure
108 as they appear in the release `.zip` archive. This can be done in the following
109 way. This will install to `c:\workspace\bitcoin`, for example:
111 make install DESTDIR=/mnt/c/workspace/bitcoin
