Hello, I need to develop for ARM CPU : - ARM CPU, with 250…512 MB Ram - Ethernet+USP+I2C communications - graphic display (LCD…) - linux as firmware Is it possible to use ruby + Gtk for this kind of target ? Should we recompile (ruby) + Gtk + ruby-gtk ? Thank you, ============ NOTA: At first watch, we found ISEE hardware : - IGEP COM on Paris or Berlin package - 500…1000 $ for complete package (cpu+display+ power convertissor…) - “IGEP Firmware Yocto: a lite X Window System with GNOME Mobile based applications” - Industrial range : -40 to 85ºC [https://www.isee.biz/products/igep-processor-boards/igep-com-module-dm3730](https://www.isee.biz/products/igep-processor-boards/igep-com-module-dm3730) Raspberry Pi seem to weak for our usage, perhaps arduino Tre could be ok. ---

I have done some tinkering on a so-called ‘Olinuxino.’ See here: > **[OLinuXino - Industrial Linux SBC - Open Source Hardware Boards](https://www.olimex.com/Products/OLinuXino/)** > > OLINUXINO is Open Source software and Open Source Hardware, low cost Linux Industrial grade single board computer with GPIOs capable to operate -25+85C. These are boads based on Allwinner CPU’s - A13, A10s, A10 and A20. I tinkered with the A13 model (1GHz single core) but double-core A20-based boards are available. They are made in Bulgaria (!) by a company with quite a long history. Boards are open-hardware - CAD files can be downloaded. A20 is a Cortex-A7 and A13 is a Cortex-A8. There is a bootable Debian MicroSD. Once you have Debian running, experience is not much different from what you generally get on your PC. I was personally interested in some low-level stuff, so I compiled my own kernel and used mruby rather than full-blown ruby. And I did not use Gtk (or X) (have a look at [GitHub - asfluido/olinuxino: A mruby gem to dabble with an olinuxino A13 · GitHub](https://github.com/asfluido/olinuxino) to read more about the little bit of work I did). But experience suggests to me that, if you install Ruby and Xfce from Debian, and are patient enough during compile, the default ruby-gnome distribution will build normally, directly onboard (I use Ruby-gtk on a day-to-day basis on PC). More information on Linux for Allwinner CPUs can be found on [http://linux-sunxi.org](http://linux-sunxi.org) HTH Carlo PS I am not connected with Olimex - just a client – - ``` Se la Strada e la sua Virtu' non fossero state messe da ``` parte, - K \* Carlo E.

Mruby is still young, but it was a pleasure to work on, and extend using C.

Most of the problems I see on this list are windows-related. When you have debian running, there is really no difference whether you run on a couple of Xeons, or a humble ARM - apart from having to wait a long time for compilation. After all, my fortran programs back in the eighties also took a long time to compile! I did not directly experiment with gtk on the Olinuxino because I only have a 4.3" screen, which makes using X a bit awkward. But from my experience, once I had Ruby and the Gnome dev libraries installed from Debian, I see no special problems in getting the ruby-gnome repo from github and recreating on a 45€ ARM board the same development environment that I am using for the boring data-entry programs that I have to be busy with in these gloomy days. Of course, whether this sort of solution cuts your cake depends on the cake itself. You may have to get your hands a litte bit dirty, but that’s the funny part.

Very interesting , mruby is it practicable ? there are very few witness on mruby+ARM usage ! > And I did not use Gtk (or X) This was my question… Watching issue log of ruby-gtk project, generation seem hard.
