Dingoo A320 forum

Hi,

I'm trying to get the Qt Embedded framework running on Dingoo Linux. Qt is a very good multi-platform framework (user interface, graphics, sound....). I compiled the Qt Embedded sourcecode using the Ingenic toolchain, but currently I do not yet succeed in running the example applications. I get the following messages in the console:
QWSServerSocket::init: Function not implemented
QWSServerSocket: unable to create socket.
QWSServerPrivate::initServer: server socket not listening: Illegal seek
Failed to bind to /tmp/qtembedded-0/QtEmbedded-0
Aborted

Did anybody else already tried to get Qt running on the Dingoo?

It looks like you'll have to enable unix sockets and recompile the kernel. They're disabled in the build booboo put up as there is obviously no network device and it saves some memory, but a few other people have had similar problems with programs that use sockets locally.

Thanks for the quick answer. I'll look into that.

I've made a simple test program with Qt4 before but didn't used it since then. Is it possible to use Qt to make programs that output graphics in Dingoo? I thought that the X server have to be running to use Qt Sorry if I sound stupid - I am missing something important here..

There's a version of Qt that is aimed at mobile/embedded devices: Qt Embedded.

Some videos of user interfaces made with Qt Embedded:

It runs without an X server and draws directly into the Linux framebuffer. A lot of mobile devices already use it and since a few months it's completely free, even for commercial applications. Qt would be ideal to make a fancy menu system for the Dingoo and to be a platform for all kinds of applications. Using a higher level toolkit such as Qt would really speed up development.

Hi,
I know that qtopia (aka qtembedded) has alreadi been ported on JZ4740, here the link with details:

hope you can find help!

Great, MasterTutu!
Qt was fun back then when I've tried it and it's very advanced so I am going to learn a thing or two about the embedded version.
Thank you!

Sweet those vids look pretty cool... Think I'm going to look into qt now lol

rhings are get better n better everyday...

I can run the Qt example applications, but they don't seem to get any input from the Dingoo buttons. I launched the applications using Teraterm on Windows. Does anybody what might need to be done to get Qt to receive key events? By default, Qt listens to TTY for input.
