# Aleth – Ethereum C++ client, tools and libraries
> The collection of C++ libraries and tools for Ethereum,
> formerly known as _cpp-ethereum_ project.
> This includes the full Ethereum client **aleth**.
## ⚠️ **This project has been discontinued and is no longer maintained.**
## Contact
[](https://gitter.im/ethereum/aleth)
[](https://github.com/ethereum/aleth/issues)
- Chat in [aleth channel on Gitter](https://gitter.im/ethereum/aleth).
- Report bugs, issues or feature requests using [GitHub issues](https://github.com/ethereum/aleth/issues/new).
## Usage
The Ethereum Documentation site hosts the **[aleth homepage](http://cpp-ethereum.org)**, which
has a Quick Start section.
Operating system | Status
---------------- | ----------
Ubuntu and macOS | [](https://travis-ci.org/ethereum/aleth)
Windows | [](https://ci.appveyor.com/project/ethereum/cpp-ethereum)
## Install
### Download release binaries
https://github.com/ethereum/aleth/releases
### Using docker images
Aleth:
```bash
docker run ethereum/aleth --help
```
Testeth:
```bash
docker run ethereum/testeth --help
```
### Building from source
#### Get the source code
Git and GitHub are used to maintain the source code. Clone the repository by:
```shell
git clone --recursive https://github.com/ethereum/aleth.git
cd aleth
```
The `--recursive` option is important. It orders git to clone additional
submodules to build the project.
If you missed `--recursive` option, you are able to correct your mistake with command
`git submodule update --init`.
#### Install CMake
CMake is used to control the build configuration of the project. Latest version of CMake is required
(at the time of writing [3.9.3 is the minimum](CMakeLists.txt#L5)).
We strongly recommend you to install CMake by downloading and unpacking the binary
distribution of the latest version available on the
[**CMake download page**](https://cmake.org/download/).
The CMake package available in your operating system can also be installed
and used if it meets the minimum version requirement.
> **Alternative method**
>
> The repository contains the
[scripts/install_cmake.sh](scripts/install_cmake.sh) script that downloads
> a fixed version of CMake and unpacks it to the given directory prefix.
> Example usage: `scripts/install_cmake.sh --prefix /usr/local`.
#### Build
Configure the project build with the following command to create the
`build` directory with the configuration.
```shell
mkdir build; cd build # Create a build directory.
cmake .. # Configure the project.
cmake --build . # Build all default targets.
```
On **Windows** we support Visual Studio 2017, and 2019. You should generate a Visual Studio solution file (`.sln`) for the 64-bit architecture via the following command:
* **Visual Studio 2017**: `cmake .. -G "Visual Studio 15 2017 Win64"`
* **Visual Studio 2019**: `cmake .. -G "Visual Studio 16 2019" -A x64`
After the necessary dependencies have been downloaded and built and the solution has been generated, `aleth.sln` can be found in the
`build` directory.
#### Common Issues Building on Windows
##### LINK : fatal error LNK1158: cannot run 'rc.exe'
Rc.exe is the [Microsoft Resource Compiler](https://docs.microsoft.com/en-us/windows/desktop/menurc/resource-compiler). It's distributed with the [Windows SDK](https://developer.microsoft.com/en-US/windows/downloads/windows-10-sdk) and is required for generating the Visual Studio solution file. It can be found in the following directory: ```%ProgramFiles(x86)%\Windows Kits\\bin\\\```
If you hit this error, adding the directory to your path (and launching a new command prompt) should fix the issue.

The current codebase is the work of many, many hands, with over 100
[individual contributors](https://github.com/ethereum/aleth/graphs/contributors) over the course of its development.
Our day-to-day development chat happens on the
[aleth](https://gitter.im/ethereum/aleth) Gitter channel.
All contributions are welcome! We try to keep a list of tasks that are suitable
for newcomers under the tag
[help wanted](https://github.com/ethereum/aleth/labels/help%20wanted).
If you have any questions, please do not hesitate to ask us about more information.
Please read [CONTRIBUTING](CONTRIBUTING.md) and [CODING_STYLE](CODING_STYLE.md)
thoroughly before making alterations to the code base.
All development goes in develop branch.

## Tools
The Aleth project includes the following tools in addition to the Aleth client:
* **[aleth-bootnode](aleth-bootnode/)**: A C++ Ethereum discovery bootnode implementation
* **[aleth-key](aleth-key/)**: A rudimentary wallet
* **[aleth-vm](aleth-vm/)**: An EVM bytecode runner tool
* **[rlp](rlp/)**: A RLP encoder/decoder tool
* **[testeth](test/)**: A consensus test generator/runner tool
## Mining
This project is **not suitable for Ethereum mining** because the support for GPU mining
has been dropped some time ago including the ethminer tool. Use the ethminer tool from https://github.com/ethereum-mining/ethminer.
## Testing
Details on how to run and debug the tests can be found [here](doc/usingtesteth.rst)
