Solidity - Environment Setup
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.
Method 1 - npm / Node.js
This is the fastest way to install Solidity compiler on your CentoS Machine. We have following steps to install Solidity Compiler −
Install Node.js
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 −
3.10.10
Install solc
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 −
$solcjs-version
If everything goes fine, then this will print something as follows −
0.5.2+commit.1df8f40c.Emscripten.clang
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.
Method 2 - Docker Image
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++
Method 3: Binary Packages Installation
If you are willing to install full fledged compiler on your Linux machine, then please check official website Installing the Solidity Compiler.
