I see that there are ports of go compiler on ev3dev (ARM, debian based) for controlling the EV3 lego mindstorm robot. (http://www.ev3dev.org/docs/libraries/)

Is there a port of a D compiler for ARM? How about libraries? I need a basic file IO and console IO for controlling the robot.

Thanks in advance

GDC may work, but you will need to handle all the interfacing code to the platform. Also don't expect e.g. threading to work I suspect.

The reference compiler DMD doesn't support ARM, but LDC does and since recently it's quite up-to-date with the latest D-frontend release.
Have a look at the LDC wiki entry and the linked entries:

https://wiki.dlang.org/LDC#ARM

There's also official armv7hf release https://github.com/ldc-developers/ldc/releases

Thanks all for your replies.

I tried to use GDC first, I couldn't find windows binary targeting windows (for initial testing) which I thought was weird. https://gdcproject.org/downloads

So I tried to build it in Cygwin env, using these instructions:
http://wiki.dlang.org/GDC/Installation/Generic
(I used gcc-5.2 sources for this).

Unfortunately, it failed with the following error. Any ideas?

I am tempting towards go, looks like their windows binary supports compiling to both windows and arm. Unfortunately I don't want to use go as it lacks templates (or generics) and operator overloading, as I tend to use lot of vector/matrix math in my programs.

I've seen that error before, specifically not finding errno. If I remember right its not using the right c++ language version. That is what you should try and Google. I would do it myself but I can't right this minute.
