Quoting from the link I posted before <https://www.reddit.com/r/golang/comments/b6h8qq/is_anyone_actually_using_go_plugins/ejkxd2k/?utm_source=reddit&utm_medium=web2x&context=3> :
- The plugin compiler version must exactly match the program's compiler version. If the program was compiled with 1.11.4, it won't work to compile the plugin with 1.11.5. When distributing a program binary, you must communicate what the compiler version you used is. - Any packages outside of the standard library that are used by both the plugin and the program must have their versions match *exactly*. This means that when distributing a program binary, you must communicate the exact versions of all dependencies and: "It seems that the intended use-case for plugins is *in-tree* plugins; when you have code you don't want to always include in the main binary, but you have no problem with it living in the same git repo and getting compiled at the same time. It does *not* seem to be a good way to let users/customers add in their own code; there are headaches if you try to use them that way; they have to sufficiently emulate your environment when compiling the plugin" If you want a more generic way to do "plugin" type functionality, which is less tightly coupled, then I suggest you look at talking gRPC over a socket. There is a go-plugin library <https://github.com/hashicorp/go-plugin> for this from Hashicorp, which they use in Vault <https://www.vaultproject.io/docs/internals/plugins> etc. -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.
