I'm trying to build program found on github.(https://github.com/ginuerzh/gimme-bitcoin-address)

I have been programming in golang for half a year, but I have never encountered a situation where the program lacks the "go.mod" file or the main function.

Build instruction looks like this, but you can't build without go.mod file, so I use go mod init ... , but it is not my question here.

$ git clone git://github.com/vsergeev/gimme-bitcoin-address.git
$ cd gimme-bitcoin-address
$ go get code.google.com/p/go.crypto/ripemd160
$ go build

go build isn't building anything ofcourse

Worth to notice is that go get ... is outdated, and you have to import "golang.org/x/crypto/ripemd160"

Project structure looks like this:

gimme-bitcoin-address/
 |-- LICENSE
 |-- README
 |-- gimme-bitcoin-address.go
 |-- gimme-bitcoin-address_test.go

And, as you see there's no main.go file, but as before this is not real problem.

Only one able-to-build file (except the xx_test.go) is gimme-bitcoin-address.go, let's look at the code.

Instead of package main, there's package btcaddr, what else the function that is closest to the main function is func _main

To sum this all up - my question is how can I run this program, after cloning repository, or how to fix it? I dont't really know but, maybe this is some old-fashioned syntax, but function _main is not called anywhere. It's probably quite newbie question, but I can't handle it. I hope maybe someone would help me.

  • The linked repo isn’t a main package, and the directions don’t make sense. This isn’t a problem with the version of go. – JimB Aug 26 '22 at 20:51

If you are just trying to build the project, the following should work:

$ cd /tmp
$ go version
go version go1.18.5 linux/amd64

$ git clone https://github.com/vsergeev/gimme-bitcoin-address.git

$ cd gimme-bitcoin-address/
$ ls

This is from an Ubuntu 20.04 Windows Subsystem for Linux environment using Go 1.18.5.
