Qt on embedded Linux

February 2, 2009 · Posted in Gentoo

Embedded Linux has become a great part of my life lately. I have to develop some applications using RTAI and RTNET . Since I am a Qt junkie I decided to bring the power of Qt on my embedded systems :) ( Note that all of them run Gentoo since I need to change the kernel configuration all the time , and because I love Gentoo anyway :P ). So , I brought qt-embedded-4.4.3 package on qting-edge overlay. I am aware that there is qt-embedded-3.3.8 on portage but who uses Qt3 anyway? :P

Of course it’s hard to cover every embedded linux configuration, so I would advise you ( as the ewarn message states ) to modify the configure options inside the ebuild to fit your system configuration.

Enjoy :)

Nice, this may be interesting to have on gentoo for openmoko :p

This is great news – Qt/Extended support was exactly the issue I’ve been wrestling with!

Ultimately (for my particular use) I will need to overlay the ebuild for it anyway, because I am using a commercial license for a project I’m working on – but it should nearly be a copy/paste operation at that point.

I try avoid modifying upstream ebuilds, so as not to interfere with updates; if I do have to, I maintain my own overlay for those cases. I suspect that many configuration cases could be controlled via USE flags, and I would think most (admittedly not all) of the rest could be handled by variables set in /etc/portage/env.

Thanks much for this work, I will go get this overlay in a bit!

Having so many use flags to cover every embedded board configuration wouldnt be handy. So this ebuild is for generic purpose and should fit most embedded configuration.
If you can come up with a better implementation I would be glad to adopt it since I dont have much time to maintain this package and run as many tests as I’d like :(
