Cannot Navigate to functions / symbols from _windows.go on MacOS

[wayneforrest]

Type: Bug

On MacOS, create a windows specific file i.e. main_windows.go
and then navigate to functions/symbols that are not OS specific.

I observed the following in the console which might be related.

ERR getting file for InlayHint: no package metadata for file file:///Users/user_name/Documents/Projects/project_name/project_name-lib/main_windows.go: Error: getting file for InlayHint: no package metadata for file file:///Users/user_name/Documents/Projects/project_name/project_name-lib/main_windows.go

Hi, what is your gopls version? This should have been fixed in gopls@v0.15.x.

Please run gopls -v version and share the output.

Thanks. This doesn't reproduce for me. When I create a main_windows.go, gopls indeed works as expected -- for example I can jump to definition.

Can you share exact steps to reproduce? Are you just creating a main_windows.go file in an empty workspace folder?

[wayneforrest]

@findleyr thank you for assisting. I will only be able to try this later tonight. I will then experiment and see what is going on.

I also have a main_darwin.go file together with a main_windows.go file, and both then reach out to normal go files.
I can navigate from the darwin file, but not from my windows file. (Also this is done from MacOS). Perhaps some environment vars are at play here?

But I will try again tonight, and get back with more details (it might just be this project).

[wayneforrest]

Hi @findleyr, I have managed to reproduce the problem. (well I think so).

1: create two files. main_windows.go and main_darwin.go, both having func main() defined in them.
2: create a package called callme, and in it a func CallMe() { fmt.Println("called me") }
3: in both files add a import "C" line
4: call the function callme.CallMe() from within the main function.

As soon as I add the import "C", I am unable to navigate, from the main_windows.go file, to the function definition of CallMe(), by using the command key and the mouse:CMD+Mouse+Click.

@wayneforrest Thanks for the repro, I was able to reproduce the issue locally when using cgo as well.

@findleyr this comment from the zero-config issue seems to refer to this same problem.

[findleyr]

This is indeed a known issue. Setting GOOS or GOARCH do a cross-platform value implies CGO_ENABLED=0 (because we have no C compiler).

We could do better here, but that is covered under #35721 among other issues. Closing as a dupe.

(Since this was just raised again, I'm going to experiment with using go/types.Config.FakeImportC to work around this issue).

[findleyr]

This is actually a better dupe of golang/go#65758.
