Thank you for filing a gopls issue! Please take a look at the Troubleshooting guide, and make sure that you have provided all of the relevant information here.

The problem seems to be caused by the build constraint // +build linux . Removing the build constraint makes the problem go away.

However I would expect gopls to work on files with a build constraint

gopls doesn't yet work automatically with build tags (#29202 is the tracking issue), but you can explicitly specify your build tags in your settings as a work-around. For example:

"gopls": {
    "buildFlags": ["-tags=linux"]
}
