如何在Mac上针对Ubuntu交叉编译Go程序？

Question

vagrant@precise64:/vagrant$ sudo ./myprogram 
./myprogram: 1: ./myprogram: Syntax error: "(" unexpected

I found out this happens when I do not generate the binary file from the same OS. I do go build with Mac OS but I need to run this binary from Vagrant that uses Ubuntu Linux. What command should I use instead of go build from Mac so that I can run the binary program in Vagrant environment?

You need to set up a cross-compilation environment (by building the go compiler yourself). Dave Cheney's blog has good instructions: http://dave.cheney.net/2013/07/09/an-introduction-to-cross-compilation-with-go-1-1
