I have decided it is time to have means to test U++ with ARM. In the end, Raspberry PI is perhaps too slow, so instead I have decided to get

http://www.bananapi.org/p/product.html

This thing has 2 CortexA7 cores at 1Ghz and 1GB RAM, plus 1G ethernet.

I have installed bananian (basically, Debian Wheezy) and after getting MATE desktop to work (it is quite usable), I simply downloaded U++ nightly, used its 'debian' script (worked without problem), then fired make. I had 2 issues: there was wrong __arm macro used in Core/Config.h (has to be __arm__ - already commited) and then I had some weird linker issue, which could be worked around. Then make gone through and create ./theide, which, to my surprise, immediately worked.

Overall, whole thing feels like slower version of my normal Linux desktop (while being absolutely silent and consuming about 2W of energy).

I plan to setup this 'station' for automated testing (to complement x86 tests).

Funny facts: It takes 30 minutes to compile TheIDE in debug mode and 138 for release mode... Smile

Hello Mirek,

I have already run Upp on a Gumstix Overo board with LCD touchscreen. It worked fine, I only had a few modifications to make.
The modifications are mainly aimed at good MT management : I had problems with it, I posted the info here : http://www.ultimatepp.org/forums/index.php?t=msg&th=7165 &goto=38443&#msg_38443

The files modified are the following (diff today's svn version : 7977 )
  • Core/Mt.cpp
  • Core/Mt.h
  • CtrlCore/CtrlCore.upp this modificaqtion works on my home Fedora linux as well, but was needed by the linux angstrom

I joined the modified files
  • Attachment: ArmModif.gz

Very nice tests. It would be curious to see in how many different devices U++ is working Smile

Best regards

There are little reasons why it should NOT work, as long as target is capable of running X11.

At this moment, the only untested feature is big-endian mode. But those platform are increasingly difficult to find...

Actually U++ supports framebuffer-based rasterization and it is certainly one of biggest advantages among competitors (like qt). That is why, in my opinion, we must have framebuffer infrastructure working well. U++ is lightweight and effective which is the second big advantage on ARM and MIPS CPUs.
So we really have an opportunity to make U++ one of widespread frameworks for embedded systems.
My experience with U++ on slow systems shows it's fully capable and robust. With its lightness, effective basic structures and standalone GUI, U++ is worth being leading embedded framework.

There is a quadcore raspberry pi now:
http://www.cnet.com/news/raspberry-pi-2-model-b-is-a-quad-co re-upgrade-on-sale-today/

And a compatible Chinese alternative that is 50% faster: (but also just $35)
http://www.hardkernel.com/main/products/prdt_info.php?g_code =G141578608433
(they also have an 8 core version with 2gb ram, but that one costs a lot more)
