Cross compiling Qt for the masses

Published Friday April 13th, 2012 | 13 Comments on Cross compiling Qt for the masses
Posted in Contributors, Embedded, Open Governance, Qt

Cross compiling Qt for particular devices/BSPs can be frustrating when operating from first principles and we are trying to improve the existing configure/qmake build infrastructure in Qt 5, as well as the associated documentation, in order to ease this burden. We are approaching the problem from 2 angles: General cross compilation support Direct target support […]

Raspberry PI: A case study in deploying Qt apps to generic Linux devices

Published Thursday January 19th, 2012 | 13 Comments on Raspberry PI: A case study in deploying Qt apps to generic Linux devices
Posted in Embedded, Qt, Qt SDK, QtCreator

Overview This is an awfully dry post; dry due to the sheer logistic nature of it. This functionality exists and is quite straight forwards to stumble upon. This blog exists in order to draw your attention to it and hopefully minimize the stumble time. You have a device: 1) Running an ssh server 2) With […]

QtQuick 2 promises superior performance, a new particle system and a host of new possibilities: http://doc.qt.nokia.com/qt5/qtquick2-whatsnew.html It is also quite ripe for testing if you are into that kind of thing. This is my personally recommended approach to testing QtQuick 2 on your n9(50) at this point in time and I have to stress that […]

Chasing the raspberry pi dragon: OpenGL ES2 accelerated Qt PI

Published Monday October 3rd, 2011 | 18 Comments on Chasing the raspberry pi dragon: OpenGL ES2 accelerated Qt PI
Posted in C++, Embedded, Kinetic, Lighthouse, OpenGL, Performance, Qt Quick

The raspberry pi initiative is very compelling and (forgive me for the hype) just got even more compelling now that we have Qt 5 running with full acceleration on the target. A tagline of “An ARM Linux box for $25. Take a byte!” sums it up rather nicely and should get many a geeks pulse racing. […]

Hitching Qt/Embedded to a framebuffer OpenGL ES (2) abstraction

Published Thursday August 5th, 2010 | 13 Comments on Hitching Qt/Embedded to a framebuffer OpenGL ES (2) abstraction
Posted in Embedded, Lighthouse, OpenGL

People (customers in my case) often find themselves in a situation where they have OpenGL ES 2 libraries for their hardware and want to use their hardware’s OpenGL capabilities in conjunction with Qt. If they are using Qt/X11 the complexity is drastically reduced, and all they basically need to do is establish what the required […]

Qt/X11 bring up on Tegra2 with full OpenGL ES 2 support

Published Friday February 5th, 2010 | 15 Comments on Qt/X11 bring up on Tegra2 with full OpenGL ES 2 support
Posted in Build system, Embedded, OpenGL

Requirements 1) Tegra 2 platform 2) The latest Nvidia Tegra2 SDK (11.0074_devlite_eula_Beta-RC.zip at this time) Board bring up Nvidia have done a pretty good job in documenting bring up and I will not paraphrase them. I personally used their dev environment exactly as intended (answering every question posed during installation with an affirmative), so my […]

Introduction Texas Instruments has a wiki which documents what is required to bring Qt up on the Beagle board with full OpenGL ES (1/2) support: http://www.tiexpressdsp.com/index.php/Building_Qt and I would like to thank one of their engineers, Varun, for his quick turn around times in addressing any questions I raised. This blog entry is intended to […]

Cross compiling Qt/X11

Published Thursday September 10th, 2009 | 14 Comments on Cross compiling Qt/X11
Posted in Build system, Embedded, Qt

Overview Cross compiling Qt Embedded is relatively trivial since it is so self contained, but as the number of external dependencies increases (DirectFB, D-Bus, GStreamer, OpenGL ES) adjusting your custom mkspec to individually account for the location of dependencies on the host machine becomes increasingly tedious/untidy. This complexity culminates in cross compiling Qt/X11 which adds […]
