Arago install help for a newbie

GoogleGroups
1

I just got my BB-xm and I would like to install Arago, but I can't
seem to find instructions anywhere. There seems to be quite a few
places that have builds for it; but where are the official builds?

Have you tried angstrom? That's like arago, but faster since it will use VFP instructions in libm and friends.

regards,

Koen

From what I understand, the binaries for arago aren't kept up-to-
date. If you want to use arago you will need set up the build
environment and build it yourself.

The main wiki page is here:

and the detailed instructions for building are here:

Well maybe I should be using angstrom. Basically my project is QT
program which writes a GUI to the framebuffer and accesses the
Internet via Ethernet. I had thought that Arago was a "refined"
version of angstrom for the Logicpd Zoom, Beagleboard and Beagleboard-
xM.

So should I be using angstrom?

And when I see a angstom build for a Beagleboard does that include a
Beagleboard-xM?

Thanks!

"Refined" isn't the word I would use. Not using the VFP is a bit well, unrefined.

Yes

Yes

I don’t understand why you should use any of distributions for QT project? I usually do the following things for QT applications:

  1. build small filesystem with busybox
  2. use QT application in framebuffer mode, specifically with “-qws” option

thats all! You don’t have to wait for X11 or other huge stuff to start while QT applications are usually self-sufficient.

correct me if I’m wrong.

Well, althought such a workflow might be OK for the development or some
hobbyist project, can you tell me how would you update say more then a few
devices, say for example on the remote sites?

Please note, that I'm not the OE/Angstrom advocate, but with OE/Angstrom[1]
you get easily package system(s) and package repositories, automatic package
build/run dependecies, NFS/UBIFS/JFSS2/YOUNAMEIT filesystem images, build
reproducibility, native SDKs and much more, for free, without much hassle.

Simply said, if you're going to solve real life problems on a few embedded
platforms, be it MIPS/ARM920T/AVR32/OMAP/PPC, it's nearly impossible or pain
without OE/Angstrom :slight_smile: Not mentioning the great and skilled community around
it. I or anybody else can give you for sure milion of other examples, but it
would be quite offtopic and useless here.

1. I hate to mention both, I preffer to just write OE, but Koen would probably
   slap me with some large and stinky trout :slight_smile:

Good to know. I am not using X11 and I am using the framebuffer, but
I am using many other Linux features,
like remote logging, ftp, telnet and such.

I would of thought that QT would of at least needed a POSTIX compliant
OS.

Just to clarify, you will need a running OS (such as Linux), you just
don't have to run X11. If you want a stand-alone Qt application you
can use the -qws option.

…and you will have all necessary services like ftp, telnet etc. if you set them. No need for Armstrong as QT work perfect with FB.

P.S. Linux is 100% POSIX compliant!
