The first one-hands-on teach you how to clean up the various development environment of EOS __eos

At present, any study of EOS related technology from Https://github.com/EOSIO/eos, may be in the process of building the EOS development environment, will be very confused, online data are very messy, they can not understand the clue, do not know how to start. Here, Brother Chun will be a step by step for you to uncover layers of veil. 1. Hardware Software Environment

Because there are too many versions of EOS, you need to know how to view the relevant data for the EOS version first.

Open the EOS GitHub official website Https://github.com/EOSIO/eos, as shown in the following figure, click Master, and then click on tag, and you will see different versions and their corresponding documents.

I have installed various versions of my computer, stepped on a variety of inexplicable pits, this article I will be the following configuration for you to share. Operating system

EOS version

2. Compile Settings development environment 2.1 get EOS Source and all its sub modules

$ git clone Https://github.com/eosio/eos--recursive

If the code is cloned without the--recursive parameter, you can switch to the project path to perform the following command to update the child module.

$ git submodule update--init--recursive

2.2 Compiling the source code to generate the executable file

Switch to the above project root directory, and execute the following command.
