Add private linter to golangci-lint

[behzadsh]

Hi everyone.

I created a custom linter using go/analysis and followed the documentation. I built my plugin and build golangci-lint separately, added the custom linter config to .golangci.yml of my project. But when I run the linter I get the following error

ERRO Unable to load custom analyzer mylinter:mylinter.so, plugin.Open("/path/to/mylinter"): plugin was built with a different version of package golang.org/x/sys/execabs

There's also another discussion with no answer.
#2529

Hi,

plugins and golangci-lint must be compiled with the exact same stack, it's related to how Go plugins work.

It's a constraint that is not possible to overcome because it's a Go constraint.

what do you mean by "exact same stack"? I built both of them on the same machine.
Can you explain a little more?

From my memory:

• exact same Go version
• same OS/arch
• same version of shared dependencies

In your case, you are using a different version of golang.org/x/sys than golangci-lint.

Ok, thanks. based on what you said I think the problem is the third one.
I'll check it. thanks again.
