This chapter explains how we can setup Solidity compiler on CentOS machine. If you do not have a Linux machine then you can use our Online Compiler for small contracts and for quickly learning Solidity.
This is the fastest way to install Solidity compiler on your CentoS Machine. We have following steps to install Solidity Compiler −
First make sure you have node.js available on your CentOS machine. If it is not available then install it using the following commands −
# First install epel-release $sudo yum install epel-release # Now install nodejs $sudo yum install nodejs # Next install npm (Nodejs Package Manager ) $sudo yum install npm # Finally verify installation $npm --version
If everything has been installed then you will see an output something like this −
Once you have Node.js package manager installed then you can proceed to install Solidity compiler as below −
$sudonpm install -g solc
The above command will install solcjs program and will make it available globally through out the system. Now you can test your Solidity compiler by issuing following command −
If everything goes fine, then this will print something as follows −
Now you are ready to use solcjs which has fewer features than the standard Solidity compiler but it will give you a good starting point.
You can pull a Docker image and start using it to start with Solidity programming. Following are the simple steps. Following is the command to pull a Solidity Docker Image.
$docker pull ethereum/solc:stable
Once a docker image is downloaded we can verify it using the following command.
$docker run ethereum/solc:stable-version
This will print something as follows −
$ docker run ethereum/solc:stable -version solc, the solidity compiler commandlineinterfaceVersion: 0.5.2+commit.1df8f40c.Linux.g++
If you are willing to install full fledged compiler on your Linux machine, then please check official website Installing the Solidity Compiler.
