I want to compile Protoc for object detection api of Tensorflow will it work for that too, i am using ubuntu 18.04

you might need to install a dep too:

sudo apt-get install libatomic1

I was able to get what I needed with sudo apt-get install libprotobuf-dev protobuf-compiler

@cboulay apt install gets 3.0

I'm using Ubuntu 18.04, install protoc using this, and when I tried to compile my .proto file it said

protoc-gen-go: program not found or is not executable
--go_out: protoc-gen-go: Plugin failed with status code 1.

while run protoc-gen-go tell me

zsh: command not found: protoc-gen-go

Any idea how to make it works? Thanks

same problem

Install protoc-gen-go using:

sudo apt install libprotobuf-dev protobuf-compiler golang-goprotobuf-dev -y
