Building the source code

Minimum requirements

Components Version Description
Golang ≥ 1.17.3 Go programming language
Protoc ≥ 3.6.0 Protocol buffers, required only when you rebuild protobuf messages

Compile

Download the code to your desired local location (doesn't have to be under $GOPATH/src)

git clone git@github.com:iotexproject/iotex-core.git
cd iotex-core

If you put the project code under your $GOPATH\src, you will need to set up an environment variable

export GO111MODULE=on
set GO111MODULE=on (for windows)

Build the project for general purpose (server, ioctl) by

make

Build the project for broader purpose (server, ioctl, injector...) by

make all 

If the dependency needs to be updated, run

go get -u
go mod tidy

If you want learn more advanced usage about go mod, you can find out here.

Run unit tests only by

make test

Build the docker image by

make docker

Run iotex-core

Start (or resume) a standalone server to operate on an blockchain by

make run

Restart the server from a clean state by

make reboot

If "make run" fails due to corrupted or missing state database while block database is in normal condition, e.g., failing to get factory's height from underlying DB, please try to recover state database by

make recover

Then, "make run" again.

Use CLI

Users could interact with iotex blockchain by

ioctl [command]

Refer to CLI document for more details.
