The docs do not mention this CGO dependency, are you sure?

- purpleidea 10mo agoI was surprised too, that I had to check the docs, so I assume the user was misinformed.
- bitbasher 10mo agoPerhaps I misremembered or things changed? For instance, the os/user results in a dynamicly linked executable: https://play.golang.com/p/7QsmcjJI4H5 https://play.golang.com/p/7QsmcjJI4H5 There are multiple standard library functions that do it.. I recall some in "net" and some in "os".
- telotortium 10mo agoos.UserHomeDir is specified to read the HOME environment variable, so it doesn’t require CGo. os/user does, but only to support NSS and LDAP, which are provided by libc. That’s also why net requires CGo- for getaddrinfo using resolv.conf
