Compiling on the Windows 2012 VM

Elastic Stack Beats

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.

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 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
