Compile for Arm processor

[jimseng]

Hi. I am just wondering if it would be hard to compile for Arm processors. I am really interested in seeing if this could run on the Raspberry Pi. It could make a really interesting cheap, low power chart plotter. I see it is heading for Android devices so available on a Raspi would be interesting.

I've tried to do it on ARM9 board running embedded Linux. Didn't succeed - one of the reasons I didn't have enough RAM (64M). Next project Alix 3D3 x86 based board also running Linux with 256M of RAM.

Interesting. The raspi is either Fedora or Debian and has 256 Mb. I might give it a go!

Good point. You really have to rethink your whole memory architecture when looking at the RaspberryPi contra a standard x86 compile - better to think more 'mobile' with your data handling too. It'd be a great project though! There are many things the RPi can be used for when it comes to developing a low cost "X"...

It should be easy, how well it works in the end is an other story.

With Cmake you can make a nice toolchain file to define the cross compilers and then configure the build with.

cmake -DCMAKE_TOOLCHAIN_FILE=../Toolchain-RasPI.cmake ..

The toochaoin file should contain defines for the compiler and paths. There are are few examples on CMakes wiki pages. I have no idea how RasPie cross compile chain look, what linux it uses and so on. I know they have a small weak Arm core thou, and good gfx. I'm not sure OpenCPN will run smooth on that hardware.

The Beagle board have a much more powerful arm core that the rasberypie if i got the specs right. I have not in detail looked at the Rasbery Pi yet thou. Beagle board we used a year or two back at work.
