Microsoft Windows SDK for Windows 7 and .NET Framework 4 - Web installer complains about .NET 4 RTM version and that it will skip installs so went with offline DVD https://www.microsoft.com/en-us/download/details.aspx?id=8442 -> GRMSDKX_EN_DVD.iso

> rm(list=ls())
> someFunction <- function(x) { return(x*someVariable) }
> invisible(compiler::cmpfun(someFunction))
Note: no visible binding for global variable 'someVariable'
# Scoping can be an issue:
> someVariable <- 1
> invisible(compiler::cmpfun(someFunction))
# No more error because of lexical scope, to solve:
> poorMansLibrary <- new.env()
> poorMansLibrary$someFunction <- someFunction
