Problem in building go software for windows

[BaseMax]

Hi everyone
Why cannot compile program for windows, while this works as well for Linux?

This library have neutralized the language cross platform supporting? Or i miss something?

[max@base test-program]$ env GOOS=windows GOARCH=amd64 go build

Have you tried with CGO_ENABLED=1?
E.g.:

env GOOS=linux GOARCH=amd64 CGO_ENABLED=1 go build ....

@abelhoula I haven't written in Go for some years.
Will try to find a Windows machine and check this. Thanks for your report.

wondering if this issue was fixed or not ?
