如何使用gccgo构建完整的go程序二进制文件？

Question

I have noticed that when using go build the binary result can be in excess of 2MB; but using gccgo the binary is less than 35k.

The other issue that I noticed when using gccgo is that the produced binary isn't runnable on another linux box (missing libgo.so I believe) but the go build binary runs just fine (so I imagine its because the binary includes all that is necessary to run?); is there a way to do this with gccgo?

You have to use the -static flag:

Use the -static option to do a fully static link (the default for the gc compiler).
