How to develop a Go plugin and compile it into a .so file using static linking.

[LegendaryGasai]

Fluent-bit provides the ability to develop plugins using Go(https://docs.fluentbit.io/manual/development/golang-output-plugins), and then compile them into a shared library with the command：

go build -buildmode=c-shared -o out_gstdout.so out_gstdout.go

to run custom plugins. However, due to differences in the base libraries, such as the version of glibc between the runtime and build environments, the out_gstdout.so file may not work properly on other hosts.

Are there any possible solutions? I have tried using musl static linking, but it doesn't seem to work.

#!/bin/bash

export CC=musl-gcc
export CGO_ENABLED=1

go build -buildmode=c-shared -o out_gstdout.so .
