With CMake and Visual Studio Express 12.0 (VS2013) CMake 3.0+ - The cross-platform, open-source make system. Visual Studio Community 2013 for Windows Desktop - VS2013 for Windows Desktop is a minimum as cpp-ethereum uses languages features not supported in 2012. The Professional edition also works. (tested 10/2014) Git for Windows 1.9.0+ - This for retrieving source from Github. 7-Zip - Ensure that 7z.exe has been added to the PATH. Execute the following step to download the latest source code C:\> git clone Execute the following commands within a command shell to download all dependencies: cd extdep C:\cpp-ethereum\extdep> getstuff.bat # you must run this script from extdep directory! Note: The 'Debug'-configuration is also supported. Execute the following commands within a command shell to build the project: First generate the ethereum solution and visual studio project files cd ..mkdir buildcd buildC:\cpp-ethereum\build> cmake -G "Visual Studio 12 Win64" .. # for cmake 2.8.12, or ...C:\cpp-ethereum\build> cmake .. # for cmake 3.x, or ...C:\cpp-ethereum\build> cmake -G "Visual Studio 12 2013 Win64" .. # for cmake 3.x x64 build Note: In-source build (running cmake in root directory) is not currently supported. double click on ethereum.sln, open open project and then click Build, or: C:\cpp-ethereum\build> msbuild ethereum.sln /p:Configuration=Release Note: The 'Debug'-configuration is also supported. After setting up the dependencies and running your first successful build, unless there are changes to any of the dependencies, you can make a fresh build from the latest code much faster by just fetching the new code and rebuilding.

How To Mine Ethereum On Windows With Your Computers Gpus

How To Mine Ethereum On Windows With Your Computers Gpus

The first step is to download the Visual Studio Express Community Edition 2013 . Next, depending on your GPU platform, you must then download the OpenCL SDK. For example, if you have AMD GPUs, the SDK to download is the AMD APP SDK v2.9.1. Similarly, for Nvidia GPUs, the SDK to download is here . Thirdly, install Git for Windows and it would be beneficial to become familiar with the commands in Git for the later steps. Fourthly, install CMake for Windows ; where you should use the installer package. Using Git, check out cpp-ethereum by opening a command prompt, finding a directory you like, typing the following command; git clone . Next, the develop branch of cpp-ethereum needs to be switched. To do this, in that same terminal, cd into the /cpp-ethereum directory (the one created by the previous Git command), and then type the following command; git checkout develop. Next, cd into /cpp-ethereum/extdep, and run the following command; getstuff.bat. After running this command, you should see numerous downloads in progress. Next, cd back into /cpp-ethereum, and run the following command; cmake -DETHASHCL=1 -G Visual Studio 12 2013 Win64 This will prepare the project for compiling. The next step is to open Visual Studio and locate the ethereum.sln solution file within the /cpp-ethereum directory. Once you have found it, open it up. Visual Studio might display complaints about some things being in the wrong format; just ignore this and let Visual Studio just do its thing. After it opens, it will scan some files and configurate to make Visual Studio happy. Following this, a list of projects should appear on your right-hand side. Locate ethminer, right click on it and select the Build option. This will build the project from source. Lots of warning boxes will appear but you sh Continue reading >>

Start Mining Ethereum: How To Download And Install Ethminer

Start Mining Ethereum: How To Download And Install Ethminer

Start Mining Ethereum: How to Download and Install Ethminer If youre like many other people who follow the cryptocurrency mining market then you have watched the meteoric rise in the value of Ethereum and Bitcoin mining. Many people are looking to cash in on this market trend through Bitcoin mining for themselves rather than buy the hot cryptocoin through online marketplaces. Ethminer is one of the recommended ways to mine Ethereum but installing it on Windows can be a little more complicated than simply hitting download then install. This step-by-step mining software instillation guide will help you through the process and get Ethminer up and running so you can dip your big toe into the mining pool. Ethminer requires you to build from source. If you have never done this before then the process may seem complicated. However, its really not too difficult to do as long as you follow the steps. A person who is relatively comfortable with working on their computer should be able to handle this. First of all, before you are able to download any cryptocurrency mining software and enter the mining pool, you will obviously need a computer. Visual Studio Express is a free compiler from Microsoft that will work just fine for what you need to do. Next, you need to download your GPU platforms OpenCL SDK. These can be found with a quick Google search. If you have AMD graphics cards then grab the AMD SDK and if you have NVidia cards then you would obviously opt for the NVidia SDK. Finding everything easy so far? Lets keep moving, then. If you dont already have Git you will need to install that as well. Also, you will have to install CMake for Windows as well. Once youve done all the above, use Git to look at cpp-ethereum. Open a command prompt, find a directory, and then type the co Continue reading >>

Install The Command Line Tools

Install The Command Line Tools

Command line tools for the Ethereum Network These are tools for blockchain developers. The command line tools will allow you to connect your server to or run your application on the Ethereum blockchain or your own private blockchain. For security purposes , three independent implementations were created for Ethereum. The clients have almost identical functionality, so the one you pick is left to personal choice on platform, language and what your planned use is for the network. If you are building a business that needs to have maximum uptime guarantees to the Ethereum network, we recommend that you run at least one instance of both clients to ensure reliability. The Go implementation is called Geth. Geth has been audited for security and will be the future basis for the enduser-facing Mist Browser, so if you have experience with web development and are interested in building frontends for dapps, you should experiment with Geth. Install Homebrew and make sure it's up to date: Then use these commands to install ethereum: brew tap ethereum/ethereumbrew install ethereum For more, see the full documentation on Mac OSX Geth Download the latest stable binary , extract it, download the zip file, extract geth.exe from zip, open a command terminal and type: chdir open geth.exe For more, see the full documentation on Windows Geth sudo apt-get install software-properties-commonsudo add-apt-repository -y ppa:ethereum/ethereumsudo apt-get updatesudo apt-get install ethereum For other environments and more instruction, see the full documentation on Geth The C++ implementation is simply called Eth. If you want added security by running two different implementations in parallel or are serious about GPU mining, then the C++ "Eth" client is for you.

I think the ppa will only work properly on 16.04. Might have to build it from source. Its called cpp-ethereum. ethdocs.org/en/latest/ethereum-clients/cpp-ethereum/ bob Jun 2 at 6:17 No wonder knowing that you can't install ethminer directly from apt install command, when I try to find ethminer package on Etherum's launchpad page , return with no avail. So basically the ethminer package doesn't belong to the ppa, it's unknown either the instruction article is outdated or other reason. I suggest you to read this , there are tutorials available on how to install ethminer from source depending on OS, though I haven't tested this method.

Want to install CPP 1.2.7 on a Lubuntu 14.04 32-Bit system. It says to do that from terminal, but do I do that from the Geth console in terminal or just straight from the terminal. The guide I downloaded doesn't use "sudo" so I am wondering. This is our guide ... ... and these are commands to execute in a bash shell, or similar, not inside the geth Javascript console. @slothbag I'll just install myself right now, and see if I can replicate. Just to verify, you run this Windows installer, right? And you are sure that the solc you are running is in C:\Program Files\cpp-ethereum? yes, that is the guide I have, but lower down, it says to use "apt-get install cpp-ethereum" and I am wondering if I need to put "sudo" in front of that command or if it runs once I open Geth console. @bobsummerwill OK, will try from terminal, but if it doesn't run, will use "sudo" in front of command @agnewpickens sudo is just to do with whether you are running the package install using your own user account, or with elevated permissions globally. Looking again at , they all have sudo. Where is the line you are seeing WITHOUT that? Might just be a bug in the docs. From those instructions, I think we're going to want everything to be sudo'd. C:\Program Files\cpp-ethereum> solc --versionsolc, the solidity compiler commandline interfaceVersion: 0.3.4-dab8902/RelWithDebInfo-Windows/msvc/Interpreter had to use "sudo" and it says I have unmet dependencies after installing repository. And to be clear, @agnewpickens, was that an UPDATE, or a fresh install? Have you do the usual update/upgrade dance? just getting this machine up, it is running Geth 1.4.6 and Wallet 7.4 been having issues on sync around block 60-70K, errors and such OK ... please could you log a new Github issue for this against .

How To Build A Private Ethereum Blockchain

How To Build A Private Ethereum Blockchain

Step 5: Create an account to use as the coinbase for your blockchain node An Ethereum account is the public key that stores ether that will be used in your private blockchain to pay for gas fees. Before we start the blockchain, we need to create an account that the mining rewards will be deposited too. You will be prompted to set a password for the account, DONT FORGET YOUR PASSWORD, you will not be able to recover it later and wont be able to spend the ether you mine or unlock that account. After entering the password twice, you should expect to get a response back like this: Address: {941f1f0b08757457be0b52d83a1e3e566473ed61} This is the public key of the Ethereum account. Ethereum convention is to prefix accounts with 0x so the account is sometimes seen as 0x941f1fobo8757457be0b52d83a1e3e566473ed61. Step 6: Create JSON File for Genesis Block to Bootstrap Private Blockchain Using a text editor, create a file CustomGenesis.json with the following contents: Step 7: Initialize the blockchain from your CustomGenesis.json file go-ethereum/build/bin/geth init ./CustomGenesis.json You should expect to see output similar to this: INFO[0223|20:20:03] Allotted 128MB cache and 1024 file handles to /home/ubuntu/.ethereum/geth/chaindata INFO[0223|20:20:04] closed db:/home/ubuntu/.ethereum/geth/chaindata INFO[0223|20:20:04] Allotted 128MB cache and 1024 file handles to /home/ubuntu/.ethereum/geth/chaindata INFO[0223|20:20:04] successfully wrote genesis block and/or chain rule set: 5dd3be94dcbf5216aaa3e82700fb51a831257df5d45d984941a0a32ee0f960d8 Congratulations! You have initialized a private Ethereum blockchain!! Before we move on, lets take a break for some optional exploration of the files we have generated.

Automation Setup For Cpp-ethereum

Automation Setup For Cpp-ethereum

At the time of writing all of the automation for cpp-ethereum is driven usinga Jenkins instance hosted at . There is a pretty alias to the setup at , but that isowned by Bob Summerwill personally, not by the Ethereum Foundation , and might end up pointing to something else at a later date. It runs in parallel with the Ethereum buildbot instance which is used for Go and Python builds. The fact that we have two different automation systems is not ideal, and is forhistorical reasons. It would make sense for us to consolidate all Ethereum Foundation projects into a single, consistentautomation setup, but that is a non-trivial amount of work. Were talking aboutthat. It will be much easier to assess that when we have completed the repo reorg for the C++ codebase. The current Jenkins setup is missing a canonical continuous integration target ,which is a major weakness. There is no single URL which you can visit to findout whether the C++ builds are working or broken at HEAD. There is not evena URL which you can visit per repository, to find if the individual repositoriesare working or broken. We are also missing automation for webthree-umbrella as a whole, to knowwhether the set of repositories which we are publishing is working or broken. What we do have is automation of our pull-requests. Those are built againstthe develop branches of the repositories which they depend on. There is amechanism for specifying alternative branches for those dependencies, when testingchanges which span multiple repositories. But it is broken . Here are the Jenkins projects for the PR automation. These are triggeredautomatically via Github webhooks whenever new PRs are created, or when the contentof the branches for existing PRs is updated: libethereum-prs - PR testing for libethereum libweb3cor Continue reading >>

How To Connect To An Ethereum Mining Pool?

How To Connect To An Ethereum Mining Pool?

How to connect to an Ethereum mining pool? Ethereum mining is best done by joining a mining pool so that there is a steady stream of Ether's into your wallet and in this guide we will show you a step by step process to do just this. In our "How to Mine Ethereum on a Windows PC" we showed you how to install all the software to get your computer mining with its graphics card and failing that, with its CPU. However this isn't the whole process, as when you mine on your own the chance of finding a block is incredibly small considering the total amount of hashing power in the network - so the best option is to join a mining pool to smooth the volatility of returns - you can read about the benefits of joining a bitcoin or ethereum mining pool here . Step 1: If you have gone through our guide here on how to set up your computer to mine ethereum you are most of the way there - in fact all you need is an address which you can get from the EthDev wallet - which is basically a nice interface to doing exactly the same process. The reason you need a wallet or address is to tell the pool where to pay your money! You don't need to sync the blockchain - the mining pool provider will do this for you! Step 2: Once you have an address you need to start ethminer - and if you haven't installed this you can do so by following the section. 2.1Now you need to download Ethminer which makes your GPU or CPU run the hashing algorithm that is integral to securing the Ethereum network through proof of work. You can download this here and be sure to scroll down to the bottom of the page to get the right version - the latest and most up to date one is right at the end. 2.2 Click on the download and click install. Your firewall can cause issues but just click allow if it does so - the same is true of Continue reading >>

IMPORTANT - If you have ever contributed code to cpp-ethereum, please look through #530 - Get to clarity on licensing and copyright and add an e-mail address for yourself to the pirate pad . Remove the Frontier canaries which we forgot to remove. This is the "Theymos fix" . Fixed security issue which meant that accounts stayed unlocked once their password has been entered until cpp-ethereum was closed. Reported by WhySoS3rious Switched to using the evmjit repo as a sub-module. Pawe Bylica is actively working on the JIT again. Enabled warnings-as-errors on all platforms. Merged most of the GCC and Clang compiler settings, for ease of maintenance Defaulted build configuration to RelWithDebInfo Support for Visual Studio 2015. We will be dropping VS2013 next release. Support for statically linked builds on Arch Linux and for partially-statically linked builds on OS X, from rainbeam . Support for building against musl C standard library. We previously implicitly assumed GLIBC, from rainbeam More work on Intel compiler support, courtesy of Robert Pancoast Fixed GCC 6 warnings for Arch Linux, by Robert Edstrm , Robert Pancoast , Christian Reitwiener , Bob Summerwill , mWo , rainbeam , WhySoS3rious The DMGs in the last few releases contained stale .app files for Mix. That has been resolved in this release. Other than that, the only change was a minor fix from RJ Catalano to match solidity changes. Many, many people are having issues with Mix crashing-at-boot on OS X. We are aware, but short of people to troubleshoot. If you can help, please do come to the mix gitter channel and we can coordinate. This release mainly makes libraries more flexible in that it allows internal functions to be called. In this release we mainly focused on the build system and changes not visible to t Continue reading >>

Mining Ethereum On Windows Tim Coulter Medium

Mining Ethereum On Windows Tim Coulter Medium

Everyday I'm travelin'. Do do do do doo do do. This is going to be a quick guide. Ive got things to do, people to see, food to digest. You get the point. Still, mining on Windows involved enough technical steps and a few random guesses along the way that its likely Ive forgotten something. Comment, and Ill attempt to fill in the spots I missed. Before I get started, most of what Ive learned comes from Geniols post on the GPU mining forum . Alot can be found there. If you have questions, its worth a read. In order to mine correctly, were going to need to run two programs. The first is ethminer, which talks to your GPUs and does all the hashing work. The second is geth, which talks to the network and keeps up-to-date with the blockchain. Ethminer is written in C++ and comes from the project cpp-ethereum , whereas geth is written in Go and comes from the project go-ethereum . Well talk about installing both, and then follow up with how youll run each together. Ethminer comes with a few mostly simple steps, but you are building from source. If you havent built anything from source before this could be daunting. Ill try to make it as easy as possible, but again, Ive got things to do and all that jazz. This should download a bunch of stuff. You just gotta wait for it to finish. Next, cd back into /cpp-ethereum, and run: cmake -DETHASHCL=1 -G Visual Studio 12 2013 Win64 This will prepare the project for compiling. Great, youre most of the way there. Next, open up Visual Studio, and then find the ethereum.sln solution file within the /cpp-ethereum directory. Open that up. Visual Studio might complain about some things being the wrong format if it does, say okay and just let it do its thing. After it opens, its gonna scan some files and do some projecty-type organizational thin Continue reading >>

Getting Started With Ethereum Using Cpp-ethereum

Getting Started With Ethereum Using Cpp-ethereum

Getting Started with Ethereum Using cpp-ethereum Our previous guides regarding mining and using Ethereums Ether (ETH) coins were based on the Go Ethereum implementation ( source ) as we find it easier to be used than the C++ implementation of the Ethereum client ( source ) even though we are actually using ethminer for the actual mining which is a part of cpp-ethereum and not go-ethereum package. The Go Ethereum implementation (geth) only comes with built in support for CPU mining, while the C++ implementation (eth) contains support for OpenCL GPU mining both as a part of the client as well as a separate miner (ethminer) and there is also a fork of ethminer with CUDA support available ( source ). So now it is time to get started with using the cpp-ethereum (eth) client for creatng a local wallet and for mining both solo on a local system or on an Ethereum mining pool using eth and ethminer. Our guide is for using eth and ethminer on Windows with binaries provided only for that OS (version 0.9.40 64-bit), though the usage should be the same or very similar on other operating systems, but you will need to compile or get binaries for the respective OS. We have tried to make the guide easy and simple to follow, so that you can begin using Ethereum and mining Ether in just a couple of minutes. First we need to create a local wallet and this is the first thing you will do when you run the eth client software. But before that a word of warning, if you have a working geth installation you should know that both Ethereum clients will use the same folder for the blockchain data by default, though the contents of the folder will not be compatible. The key files that are needed for you Ethereum wallet however will be stored in different places and each client will use ts own wallet Continue reading >>
