How to setup environment for building middleware

MacOS

• Open a terminal.

• Remove all other golang installations (which go should report that nothing found)

• Make a dir for golang mkdir -p $HOME/golang

• Update brew by brew update

• Install from brew only a golang version mentioned here: here For example: brew install go@1.xx

• Remember a golang install path (/<path-to-golang>/go@1.xx/) reported by brew

• If you have ~/.zprofile file then add these lines here, else add these lines to ~/.zshrc

export GOPATH=$HOME/golang
export GOROOT=/<path-to-go>/go@1.xx/libexec 
export PATH=$PATH:$GOPATH/bin
export PATH=$PATH:$GOROOT/bin

• After restart of the terminal you will achieve all the variables set, or you can simply load them in the current terminal window by source ~/.zprofile or source ~/.zshrc
• Make sure you have set ANDROID_HOME variable in the same file
• Install NDK 23.2.8568313 via an Android SDK Package Manager
