Error when compiling generator

[DenHayes]

I'm getting the following error when trying to compile generator and wonder if anyone has run into this before.

dennis@dev:~/snmp_exporter/generator$ make generator
go build
../config/config.go:24:2: //go:build comment without // +build comment
make: *** [Makefile:87: generator] Error 1

This is being done on Ubuntu 22.04.4 LTS

Any suggestions on how to get this to build?

That line does not exist in the source code. Are you sure you haven't made local modifications?

[DenHayes]

Nope, no modifications. I even deleted everything and started from scratch; re-cloning snmp-exporter from github.

I tried on a different server and it worked perfectly. Both are Ubuntu 22.04 LTS; there must be a missing module on the one server.
