Building from source an Ethereum node under Ubuntu 16 LTS

The program, which makes an Ethereum node in your computer, is called

geth

. “geth” is written using the GO language and the latest version depends on GO version 1.7+. Ubuntu 16 LTS has GO language package version 1.6 so to build it from source we need first to install a proper version of GO Language.

STEP 1) Install a proper version of GO Language 1.7+

In our tutorial you will install 1.9 using this howto: “Install GO language in Ubuntu 16 LTS from the official site package”

STEP 2) Update your system and install dependencies

sudo apt-get update -y
sudo apt-get install -y build-essential libgmp3-dev git

STEP 3) Get the “geth” code and compile it

git clone https://github.com/ethereum/go-ethereum
cd go-ethereum
make geth

STEP 4) Check is everything is OK, installed geth version 1.8.2-unstable

srv@local:~/go-ethereum$ cd ./build/bin
srv@local:~/go-ethereum/build/bin$ ./geth version
Geth
Version: 1.8.2-unstable
Git Commit: b574b5776695eb30e034fd8c7a468b3f03d4c6b9
Architecture: amd64
Protocol Versions: [63 62]
Network Id: 1
Go Version: go1.9.4
Operating System: linux
GOPATH=
GOROOT=/usr/local/go

* Next tutorial is getting the node up and running here!

* Troubleshooting

  • if you get
    ~/go-ethereum$ make geth
    build/env.sh go run build/ci.go install ./cmd/geth
    build/env.sh: 30: exec: go: not found
    Makefile:15: recipe for target 'geth' failed
    make: *** [geth] Error 127
    

    You did not install properly go, check our manual here: “Install GO language in Ubuntu 16 LTS from the official site package”. Check whether you source /etc/profile in your current ssh/console/login session, check if you exported the PATH, your PATH must include “your_goinstallation_path/bin”, it’s like “/usr/local/go”.

  • if you get
    ~/go-ethereum$ make geth
    build/env.sh go run build/ci.go install ./cmd/geth
    ci.go:190: You have Go version go1.6.2
    ci.go:191: go-ethereum requires at least Go version 1.7 and cannot
    ci.go:192: be compiled with an earlier version. Please upgrade your Go installation.
    exit status 1
    Makefile:15: recipe for target 'geth' failed
    make: *** [geth] Error 1
    

    The installation just uses the default installed GO language of your system, which is 1.6 and is not supported by the “geth” Ethereum program. There are two options:

When we talk for crypto currency the best source is always the GIT version (probably the best one is the stable tag, but it is safe to use the unstable, too), it is most secure source you could get. Do not download from 3rd party sites or unofficial repositories, you could lose your money.

* Here is the building output

srv@local:~/go-ethereum$ make geth
build/env.sh go run build/ci.go install ./cmd/geth
