optimal command to compile from source

[danie-dejager]

What would be the preferred and optimal build command be?
I used:

GO111MODULE=on CGO_ENABLED=0 go build -v -trimpath -buildmode=pie -modcacherw -tags netgo -ldflags="-s -w"

I get a fairly decent binary at 5.1M but for instance I then cannot compress it with UPX.

[danie-dejager]

Used one of your precompiled binaries at 4.8M, it was also compressed down to 1.6M

This repos is relying on goreleaser and and github actions to generate the releases binaries. As far as I know there is no way to use UPX with the current version. I would be happy to be proven wrong :)

[danie-dejager]

I could compress your release with upx 4.02 but not my build.

[fabio42]

Oh ok, the release process is made by goreleaser. I'm not sure what parameters are used there exactly, but I will try to figure that out. Context always help, from you other question I understand you are trying to package this as an RPM, which is actually great :)

From the documentation and the config file I defined, it seems pretty basic, and should looks like this:

CGO_ENABLED=0 go build -ldflags="-s -w"

Another important parameter would be which version of go you use for the build step.
From the logs the version go version go1.20.4 linux/amd64 was used to produce the latest binaries.
