To build TiDB from source code, you need to install Go in your development environment first. If Go is not installed yet, you can follow the instructions in this document for installation.
If you are using Linux or MacOS, you can manage Go versions with Go Version Manager (gvm) easily.
To install gvm, run the following command:
curl -s -S -L https://raw.githubusercontent.com/moovweb/gvm/master/binscripts/gvm-installer | sh
Once you have gvm installed, you can use it to manage multiple different Go compilers with different versions. Let's install Go 1.18 and set it as default:
gvm install go1.18 gvm use go1.18 --default
Now, you can type
go version in the shell to verify the installation:
go version # OUTPUT: # go version go1.18 linux/amd64
In the next chapter, you will learn how to obtain the TiDB source code and how to build it.
If you encounter any problems during your journey, do not hesitate to reach out on the TiDB Internals forum.
