Building Ethereum

Building the official Go implementation of the Ethereum protocol for Callisto Network

The requirements for building the Callisto Network's **geth **executable binary are that Golang 1.9 or higher and a C/C++ compiler be installed.

Installing Golang version 1.9

1. Verify that operating system is up to date

   sudo apt-get update

   sudo apt-get -y upgrade

2. Download Golang

   sudo curl -O https://storage.googleapis.com/golang/go1.9.linux-amd64.tar.gz

3. Unpack Golang

   sudo tar -xvf go1.9.linux-amd64.tar.gz

4. Move created "Go" folder to /usr/local/ directory

   sudo mv go /usr/local/

5. Open user profile for editing

   sudo nano ~/.profile

6. Append Go folder path to opened profile by adding the following line:

   export PATH=$PATH:/usr/local/go/bin

7. Save and close profile

   Ctrl-x

   y

8. Reload profile

   source ~/.profile

9. Verify Go installation

   go version

If the return reads go version go1.9 linux/amd64 or similar, proceed.

Installing GNU C compiler

1. Install build-essential tools

   sudo apt-get install build-essential

2. Verify installation of the gcc and make commands

   gcc -v

   make -v

If both commands display a version message without errors, proceed.

Clone the go-callisto repository

 `git clone -b CLO/1.0 https://github.com/EthereumCommonwealth/go-callisto.git`

Build geth command (or alternatively, all executables)

 `cd go-callisto`

 `make geth` or `make all`

Move the newly built binary files to /usr/local/bin directory

 `sudo mv /build/bin/* /usr/local/bin/`
