Can't compile under Windows

[ghost]

I have installed all the dependencies and they are all accessible from the cmd.
I tried with different shells (cmd/Git-bash/Git-sh), cygwin, minGW, Visual Studio Tools, nothing seems to work.

Is it possible for someone to try and compile it under Windows 10 and if successful, please report what needs to be done?
Thank you!

I've never built Rebar projects on Windows so I unfortunately have no experience with it. The issue here is that mkdir that Rebar calls has no flag -p. You state that you've tried different shells with no effect, so I assume that Rebar sidesteps the local environment uses system shell (cmd?).

Unfortunately I'm just a beginner, so if someone with experience can take a look at this it would be great.

@onwarion Could you try to reproduce it on master now? I've changed scripts in rebar.config so that they should work on Windows; I'm not sure about other parts of the build, though. What kind of environment are you normally using for Erlang projects compilation under Windows?
