SNMP Generator - make build error

Trying to follow the instructions, but get an error:

That works fine for me in a fresh directory, this sounds like a problem on your end.

I still get an error on RHEL machine when trying to "go build", on a new server as well.

[root@server-t1 generator]# go build go: github.com/go-kit/kit@v0.10.0 requires github.com/casbin/casbin/v2@v2.1.2 requires github.com/Knetic/govaluate@v3.0.1-0.20171022003610-9aa49832a739+incompatible: invalid pseudo-version: git fetch --unshallow -f origin in /root/go/pkg/mod/cache/vcs/dac3237ce23c7a321475df4e3bb8c7115ea5c093fdf9bc1798a57a9ef75ede77: exit status 128: fatal: git fetch-pack: expected shallow list

I see similar error on node_exporter on CentOS: https://github.com/prometheus/node_exporter/issues/1863

I ran into the same error on CentOS 7 with golang-1.15.2-1.el7.x86_64 (from epel repo)

I was able to successfully build the generator when switching to the v0.19.0 tag. So I suspect this was recently introduced on master. Unfortionately, my golang skills are somewhat limited. Here is a diff between both Makefiles:

go doesn't use make, so I'd suspect it's an issue with either the git or go you're using.

hi, didn't dig that much on why git version trigger this issue, but updating to git 2.24 fix this error (on centos 7)

go 1.16.2 in centos 7.9 fix it problem. Now "go build " to finished not problem.

Thank you @remijouannet & @rverdugo01; closing the issue.

[bhushan-j]

upgrading to git version 2.34.1 resolved the issue.
