To expand on this:
$ cat foo.go
package main
import (
"fmt"
)
func main() {
fmt.Println("Hello")
}
$ go build foo.go
$ file foo
foo: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), statically linked, not stripped
compared to:
$ cat bar.go
package main
import (
"os/user"
"fmt"
)
func main() {
u, err := user.Current()
fmt.Println(u, err)
}
$ go build bar.go
$ file bar
bar: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked, interpreter /lib64/ld-linux-x86-64.so.2, not stripped
- ptman 9y agoYou can usually build fully static by doing CGO_ENABLED=0 go build even when using os/user or net/
- sebcat 9y agoAt a computer with go1.4.2 freebsd/amd64 ATM (earlier was go1.8.1 linux/amd64 IIRC) and the above os/user example results in a dynamically linked ELF when built with CGO_ENABLED set to 0.
