使用get get获取展示框架时出错

Question

I want to install Revel framework with

go get github.com/revel/revel

I run it and I got error:

C:/Users/User/go>go get github.com/revel/revel

github.com revel/revel

src\github.comevelevel\server_adapter_go.go:135:79: undefined: syscall.SIGUSR2

My GOPATH var is C:/Users/User/go

The bin folder was created inside my GOPATH folder. But when I tried to run sample app, it produced similar error

The Go code src\github.comevelevel\server_adapter_go.go does not compile: undefined: syscall.SIGUSR2

Please help. Thanks
