Use GOPATH in golang makefile or init go mod first?

Question

I'm learning to write Golang makefile and got some confused me because some examples they config GO env such as GOOS, GOPATH, GOBASE before building. But normally I can use go mod init to create go module and in Makefile use go build to build my project. So what's is the best approach ?

Answer 1

Modern go code with go mod. Makefile should not include GOPATH. Just use go build is enough.
