Building for Windows¶

We support only 64-bit builds and only for the following versions of Windows:

It may be possible to get the client working for Windows 32-bit, by disabling EVMJIT and maybe other features too. We might accept pull-requests to add such support, but we will not put any of our own development time into supporting Windows 32-bit builds.

Pre-requisites¶

You will need to install the following dependencies

Software	Notes
Git for Windows	Command-line tool for retrieving source from Github.
CMake	Cross-platform build file generator.
Visual Studio 2015	C++ compiler and dev environment.

Get the source¶

Clone the git repository containing all the source code by executing the following command:

git clone --recursive https://github.com/ethereum/webthree-umbrella.git

Get the external dependencies¶

Execute the CMake script that downloads and unpacks pre-built external libraries needed to build the project:

cmake -P webthree-helpers/deps/install_deps.cmake

Generate Visual Studio project files¶

Then execute the following commands, which will generate a Visual Studio solution file using CMake:

mkdir build
cd build
cmake -G "Visual Studio 14 2015 Win64" ..

Which should result in the creation of cpp-ethereum.sln in that build directory.

Double-clicking on that file should result in Visual Studio firing up. We suggest building RelWithDebugInfo configuration, but all others work.

Build on the command-line¶

Alternatively, you can build the project on the command-line, like so:

cmake --build . --config RelWithDebInfo
