Error when Compiling WebView Example: Deprecated Function Warning and Runtime Panic

[RocketPLN]

I'm encountering a problem while trying to compile an example from the WebView GitHub repository. When using the following command:

go build -ldflags="-H windowsgui" basic.go

Go version: 1.21
Operating System: Mint 21.2

Error:

The deprecation warning can be ignored but the error is peculiar.

If I understand this correctly then the Go tooling itself is crashing while it's building the program. To me this looks like an issue with Go tooling so we can't help you with that.

Are you trying to cross-compile from Linux to Windows? If so then the command you provided is insufficient.
