So despite using julia for a while I’ve never built it from scatch, only used the binaries. I figure it’s about time.

I tried running following the windows instructions a few weeks ago, but I realized that I ran it make with `-j 4` when I only have two cores. The make process failed.

Right now if I try to run make on a julia clone I get this:

C:\Users\hp\julia2\julia\>make -j 2  
Makefile:2: /Make.inc: No such file or directory

Oh wait nevermind I forgot I had to do this in cygwin. Also had to replace all /r/n with /n. Ok well I’ve started the process we’ll see how this goes.

I’d recommend you follow the [windows instructions](https://github.com/JuliaLang/julia/blob/master/README.windows.md) precisely, to the letter, without deviation or re-ordering. Only way I’ve ever gotten it to build on Windows.
