WINDOWS BUILD NOTES
|
|
====================
|
|
|
|
Below are some notes on how to build Dash Core for Windows.
|
|
|
|
The options known to work for building Dash Core on Windows are:
|
|
|
|
* On Linux, using the [Mingw-w64](https://mingw-w64.org/doku.php) cross compiler tool chain. Ubuntu Focal 20.04 is required
|
|
and is the platform used to build the Dash Core Windows release binaries.
|
|
* On Windows, using [Windows
|
|
Subsystem for Linux (WSL)](https://docs.microsoft.com/windows/wsl/about) and the Mingw-w64 cross compiler tool chain.
|
|
* On Windows, using a native compiler tool chain such as [Visual Studio](https://www.visualstudio.com).
|
|
|
|
Other options which may work, but which have not been extensively tested are (please contribute instructions):
|
|
|
|
* On Windows, using a POSIX compatibility layer application such as [cygwin](https://www.cygwin.com/) or [msys2](https://www.msys2.org/).
|
|
|
|
Installing Windows Subsystem for Linux
|
|
---------------------------------------
|
|
|
|
With Windows 10, Microsoft has released a new feature named the [Windows
|
|
Subsystem for Linux (WSL)](https://docs.microsoft.com/windows/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. Note that while WSL can be installed with
|
|
other Linux variants, such as OpenSUSE, the following instructions have only been
|
|
tested with Ubuntu.
|
|
|
|
This feature is not supported in versions of Windows prior to Windows 10 or on
|
|
Windows Server SKUs. In addition, it is available [only for 64-bit versions of
|
|
Windows](https://docs.microsoft.com/windows/wsl/install-win10).
|
|
|
|
Full instructions to install WSL are available on the above link.
|
|
To install WSL on Windows 10 with Fall Creators Update installed (version >= 16215.0) do the following:
|
|
|
|
1. Enable the Windows Subsystem for Linux feature
|
|
* Open the Windows Features dialog (`OptionalFeatures.exe`)
|
|
* Enable 'Windows Subsystem for Linux'
|
|
* Click 'OK' and restart if necessary
|
|
2. Install Ubuntu
|
|
* Open Microsoft Store and search for "Ubuntu 20.04" or use [this link](https://www.microsoft.com/store/productId/9MTTCL66CPXJ)
|
|
* Click Install
|
|
3. Complete Installation
|
|
* Open a cmd prompt and type "Ubuntu2004"
|
|
* Create a new UNIX user account (this is a separate account from your Windows account)
|
|
|
|
After the bash shell is active, you can follow the instructions below, starting
|
|
with the "Cross-compilation" section. Compiling the 64-bit version is
|
|
recommended, but it is possible to compile the 32-bit version.
|
|
|
|
Cross-compilation
|
|
-------------------
|
|
|
|
These steps can be performed on, for example, an Ubuntu VM. The depends system
|
|
will also work on other Linux distributions, however the commands for
|
|
installing the toolchain will be different.
|
|
|
|
First, install the general dependencies:
|
|
|
|
sudo apt-get install build-essential libtool autotools-dev automake pkg-config bsdmainutils bison curl
|
|
|
|
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.
|
|
|
|
## Building for 64-bit Windows
|
|
|
|
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
|
|
|
|
Then build using:
|
|
|
|
cd depends
|
|
make HOST=x86_64-w64-mingw32
|
|
cd ..
|
|
./autogen.sh # not required when building from tarball
|
|
CONFIG_SITE=$PWD/depends/x86_64-w64-mingw32/share/config.site ./configure --prefix=/
|
|
make
|
|
|
|
## Building for 32-bit Windows
|
|
|
|
To build executables for Windows 32-bit, install the following dependencies:
|
|
|
|
sudo apt-get install g++-mingw-w64-i686 mingw-w64-i686-dev
|
|
|
|
Additional WSL Note: WSL support for [launching Win32 applications](https://docs.microsoft.com/en-us/archive/blogs/wsl/windows-and-ubuntu-interoperability#launching-win32-applications-from-within-wsl)
|
|
results in `Autoconf` configure scripts being able to execute Windows Portable Executable files. This can cause
|
|
unexpected behaviour during the build, such as Win32 error dialogs for missing libraries. The recommended approach
|
|
is to temporarily disable WSL support for Win32 applications.
|
|
|
|
Then build using:
|
|
|
|
sudo bash -c "echo 0 > /proc/sys/fs/binfmt_misc/status" # Disable WSL support for Win32 applications.
|
|
cd depends
|
|
make HOST=i686-w64-mingw32
|
|
cd ..
|
|
./autogen.sh
|
|
CONFIG_SITE=$PWD/depends/i686-w64-mingw32/share/config.site ./configure --prefix=/
|
|
make
|
|
sudo bash -c "echo 1 > /proc/sys/fs/binfmt_misc/status" # Enable WSL support for Win32 applications.
|
|
|
|
## Depends system
|
|
|
|
For further documentation on the depends system see [README.md](../depends/README.md) in the depends directory.
|
|
|
|
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\dash`, for example:
|
|
|
|
make install DESTDIR=/mnt/c/workspace/dash
|
|
|
|
You can also create an installer using:
|
|
|
|
make deploy
|
