Hi, I've been trying to compile and run the packetbeat source on the win2012 vm that is on the repository but I can't seem to get it right. It compiles ok with the _ **go build** _ command but when I try to run **packetbeat.exe -devices** I get the following exception.
`PS C:\dev\LogStack\beats\packetbeat> .\packetbeat.exe -devices Exception 0xc0000005 0x0 0x2781566 0x10f7c98 PC=0x10f7c98 signal arrived during external code execution github.com/elastic/beats/vendor/github.com/tsg/gopacket/pcap._Cfunc_pcap_findalldevs(0xc082028038,0x19b7160, 0x0) ??:0 +0x3c github.com/elastic/beats/vendor/github.com/tsg/gopacket/pcap.FindAllDevs(0x0, 0x0, 0x0, 0x0, 0x0) C:/Gopath/src/github.com/elastic/beats/vendor/github.com/tsg/gopacket/pcap/pcap.go:518 +0xf1 github.com/elastic/beats/packetbeat/sniffer.ListDeviceNames(0xc083233201, 0x0, 0x0, 0x0, 0x0, 0x0) C:/Gopath/src/github.com/elastic/beats/packetbeat/sniffer/sniffer.go:79 +0x7c github.com/elastic/beats/packetbeat/beater.init.1.func1(0xc08247c780, 0x0, 0x0) C:/Gopath/src/github.com/elastic/beats/packetbeat/beater/devices.go:21 +0x6c github.com/elastic/beats/libbeat/beat.FlagsHandlerCallback.HandleFlags(0xc082f0fc30, 0xc08247c780, 0x0, 0x0) C:/Gopath/src/github.com/elastic/beats/libbeat/beat/flags.go:35 +0x39 github.com/elastic/beats/libbeat/beat.handleFlags(0xc08247c780, 0x0, 0x0) C:/Gopath/src/github.com/elastic/beats/libbeat/beat/flags.go:26 +0xb5 github.com/elastic/beats/libbeat/beat.(*Beat).handleFlags(0xc08247c780, 0x0, 0x0) C:/Gopath/src/github.com/elastic/beats/libbeat/beat/beat.go:230 +0x4ca github.com/elastic/beats/libbeat/beat.(*Beat).launch(0xc08247c780, 0xe2fef8, 0x0, 0x0) C:/Gopath/src/github.com/elastic/beats/libbeat/beat/beat.go:150 +0x4c github.com/elastic/beats/libbeat/beat.Run(0xce4ca0, 0xa, 0x0, 0x0, 0xe2fef8, 0x0, 0x0) C:/Gopath/src/github.com/elastic/beats/libbeat/beat/beat.go:133 +0x6e main.main() C:/Gopath/src/github.com/elastic/beats/packetbeat/main.go:26 +0x4e`
I'm compiling and running inside the VM.

Which golang version did you use?

I'm using the one in the VM, I think is 1.5.3.

I think there is an issue with the winpcap developer pack. IIRC, it only contains a 32-bit lib. We had to perform some [workarounds](https://github.com/elastic/beats/issues/1259) to build it for 64-bit. So if you `set GOARCH=386` before running `go build` it might work. This will build a 32-bit binary.

Hi,
Thanks for the fast reply.
Will try later today and post back the results.

It is working now, following the work around.
Thanks
