How to Build

git clone https://github.com/dashhive/dashmsg
pushd ./dashmsg/

go build -mod=vendor -o dashmsg ./cmd/dashmsg/

GoReleaser

Because one of the dependencies requires CGO_ENABLED=1 and uses low-level syscalls (I have no idea why - probably completely unnecessary), it must be built on and released from the respective OSes.

goreleaser -f .goreleaser.yml --rm-dist --single-target --skip-validate

--single-target - build only for the current OS
--skip-validate - uploads the image even though it can update the checksums

Note: MacOS actually can build both the amd64 and arm64 versions on an M1.
