failed build

Output of the info page (if this is a bug)

--- Setting rtloader paths to lib:/root/datadog-agent/dev/lib | header:/root/datadog-agent/dev/include | common headers:
# github.com/DataDog/datadog-agent/pkg/secrets
pkg/secrets/check_rights_nix.go:68:32: undefined: syscall.S_IWGRP
pkg/secrets/check_rights_nix.go:86:17: undefined: syscall.S_IXGRP

Describe what happened:
cannot build an agent as it checks for the value that is defined inside a UNIX system as default:
Freebsd/stat.h (https://github.com/freebsd/freebsd-src/blob/master/sys/sys/stat.h#L261)
Looks like a problem is in GO syscall https://github.com/DataDog/datadog-agent/blob/main/pkg/secrets/check_rights_nix.go#L68

Describe what you expected:
agent is built

Steps to reproduce the issue:
follow build process from readme: invoke agent.build --build-exclude=systemd

Additional environment details (Operating System, Cloud provider, etc):
FreeBSD13.0, go 1.17

Hi @spagu, while we currently don't provide official support for FreeBSD or other BSDs, we are happy to accept PRs to make it buildable and/or fix any issues.

In this case, I would try first to build without secrets support, as in

invoke agent.build --build-exclude=secrets,systemd

since the offending file has the secrets build tag. If that doesn't work (e.g. you find more issues), feel free to comment again so that we can continue helping you.

Running into this in 2024, @mx-psi what is the official stance of the DD agent on FreeBSD? I can take a look at fixing the build issues for FreeBSD as it's a blocker for using this in OTel on FreeBSD (since the datadog exporter/receiver call into this library).

@polyrain I think #11340 (comment) still stands (we will accept PRs that make it buildable, with no guarantees that we will actively test this), but I am not on the team that would officially approve this, so I think the best we can do is that if you open a PR (start small!) I can sort it out internally to get the right people to look into it.

About this, I assume you are talking about the Collector. If so, if you want to collaborate on this I am happy to help guide you through the process (I am a Collector maintainer and have experience with this specifically with s390x and Plan 9 support). We could also make some sort of guide/blog post on opentelemetry.io about what adding support for this entailed :) Feel free to contact me on the CNCF Slack or via email.
