it seems mpd should be cross compiled

 

You don't say which ARM architecture you want, but in my Chromium OS/Crouton Ubuntu 16.04 LTS environment on my Asus Chromebook Fiip I just need to do this:

 

localhost rdale 693% uname -a

Linux localhost 3.14.0 #1 SMP PREEMPT Wed Dec 7 23:25:35 PST 2016 armv7l armv7l armv7l GNU/Linux

localhost rdale 694% sudo apt-get install mpd

You don't say which ARM architecture you want,

 

My apologies, you do say 'ARM Processor Cortex-R8', but I found that is ARMv7-R architeture when I searched for it. Is that different to armv7, what does the difference between ARMv7-R and ARMv7 mean in term of binary compatibiltiy?

Yes, I agree it is fun to learn about Linux! I would recommend MPD as a bit perfect music server as per your original question. If you can install Ubuntu on your target device, I'm pretty sure you will be able to add MPD with apt.

I suspect it's an Allwinner R8 chip, which has a Cortex-A8 CPU. ARMv7-R CPUs are not intended to run a full OS like Linux.

some guys think ARM processors are not very powerfull with linux and they think ARM processors are better for microcontrollers.

There is a wide range of ARM processors for various different applications. Cortex-R processors can't run Ubuntu because they don't have an MMU. An ARMv7-A CPU is required for that. You'd get much better advice if you told us exactly what system you're using.

Amir, "some guys" think a lot of things. :) When people discuss things in general terms, you get many opinions that may or may not be helpful in your own situation. mansr is right, the more you tell people here about your specific equipment, the better advice they may be able to give.
