Description of the problem

I used golangci-lint with tag=v1.62.2, and confirmed that the go.mod version used to generate the custom plugin is the same as tag=v1.62.2, and the go version is the same. Why is it reporting an error?

The package version corresponds to the link below
https://github.com/golangci/golangci-lint/blob/89476e7a1eaa0a8a06c17343af960a5fd9e7edb7/go.mod

Version of golangci-lint

Sorry, but I can see 0 error in the screenshot.

The text inside the go.mod is a comment coming from https://github.com/golangci/example-plugin-linter/blob/5b227aea582953badf9ebb040a5fbbc36f265b6f/go.mod#L3

Maybe your screenshot is incomplete, so copy-paste the text (please no screenshot).

From your logs:

Error: build linters: unable to load custom analyzer "example": example.so, plugin: not implemented
Failed executing command with error: build linters: unable to load custom analyzer "example": example.so, plugin: not implemented

Your problem is that your plugin doesn't implement the right elements.

You can read the documentation: https://golangci-lint.run/plugins/go-plugins/

You can also use the new plugin system https://golangci-lint.run/plugins/module-plugins/

[caiwenxuan]

golangci-lint is a binary file downloaded using https://github.com/golangci/golangci-lint/releases/tag/v1.62.2 curl
./golangci-lint is compiled.

git clone -b v1.62.2 https://github.com/golangci/golangci-lint.git
make build

From the error message, is it because the CGO_ENABLED=0 of the binary file downloaded by curl caused golangci-lint run to fail, while the binary file I generated myself succeeded with CGO_ENABLED=1

This is explained inside the documentation: https://golangci-lint.run/plugins/go-plugins/

Please read it.
