Go build error

[elisabethEmack]

Hi, I am new to go programming language. When I tried to build your code with "go build" inside 'rtp-over-quic' folder, the following error occured: ../go/pkg/mod/github.com/mengelbart/[email protected]/qlog/event.go:9:2: //go:build comment without // +build comment ../go/pkg/mod/github.com/mengelbart/[email protected]/internal/qerr/error_codes.go:6:2: //go:build comment without // +build comment udp/receiver.go:8:2: package net/netip is not in GOROOT (/usr/local/go/src/net/netip)

What should I change? Thanks in advance
