On a Raspberry Pi 1 model B I installed FreeBSD 10.3 using the SD Card Images RPI-B.
I can boot, get network, ssh into it, etc, all seems to be ok and functional. This is part of the dmesg output:
FreeBSD 10.3-RELEASE #0 r297264: Fri Mar 25 08:01:14 UTC 2016

On a mac os X (10.11.6) with go 1.7.1:
go version go1.7.1 darwin/amd64
I am cross compile this code:
package main
import (
"fmt"
"time"
)
func main() {
t := time.Now().UTC()
fmt.Println("Location:", t.Location(), ":Time:", t.Format(time.RFC3339Nano))
}
With:
env GOOS=freebsd GOARCH=arm go build
Running the generated binary on the raspberry-pi generates a coredump:
freebsd@rpi-b:~ % ./time
Illegal instruction (core dumped)
On the time.core after typing:
$ strings time.core
besides many characters I see this:
fatal error: cgo callback before cgo call
Any idea how what flags to use or how to properly cross-compile for FreeBSD within a Raspberry pi ?
