protoc: command not found (Linux)

Question

I am trying to use Protobuf on Linux box. I downloaded the pre-compiled from github.

When I try to compile my .proto file or just check the protobuf version, it says

protoc: command not found.

I tried the same steps on Windows machine using pre-compiled protobuf version and it works fine there.

Answer 1

Install protoc for Linux and Mac

Linux

PROTOC_ZIP=protoc-3.15.8-linux-x86_64.zip
curl -OL https://github.com/google/protobuf/releases/download/v3.15.8/$PROTOC_ZIP
sudo unzip -o $PROTOC_ZIP -d /usr/local bin/protoc
sudo unzip -o $PROTOC_ZIP -d /usr/local include/*
rm -f $PROTOC_ZIP

Mac OS X

brew install protobuf

Alternately, if you don't have Homebrew.

PROTOC_ZIP=protoc-3.15.8-osx-x86_64.zip
curl -OL https://github.com/google/protobuf/releases/download/v3.15.8/$PROTOC_ZIP
sudo unzip -o $PROTOC_ZIP -d /usr/local bin/protoc
sudo unzip -o $PROTOC_ZIP -d /usr/local 'include/*'
rm -f $PROTOC_ZIP
