Very nice, I'm trying to do  the same with kdevelop and a full openembedded
tree, and got some ideas: setup "debug run" scps the executable on a qemu
emulator and launch it, setup "project run" to do the same but on the real
device.

You may consider to try this on eclipse.

Hi,

I began a Howto based on the Wiki Article "Development with Eclipse" 
(http://wiki.openmoko.org/wiki/Development_with_Eclipse) how i got C++ and Qt4 
with Eclipse and Toolchain work on my ubuntu-system.

It's just my experience and i have only tried to compil some example 
programms, but they worked. So feel free to correct/fix it.

In qtopia snapshot sources there are device specification only for the
gta01, however in the sources you can find various fixes for gta02, so I
think this works for both devices.

Hi Erin,
I have to build qt as i use c++ for my applications, so I need staging file
in the oe tree.

Also, not sure what you are interested in qt4? i am trying webkit

I'm trying to complete and port yet another gps application for the

Re: [FSO] How to develop with Qt

Hi Nicola,

I've sent some patches to our distro team and OE can use bitbake to
build the latest qt4-x11-free to version 4.4.1. Since people from
community like to try qt4 new features, I will send an email to our
distro and they would help to put these packages to our feed. Then you
can install them from installer, no need to build it by yourself.

Also, not sure what you are interested in qt4? i am trying webkit
features by python-pyqt.

Next time try separating your text into shorter paragraphs, it's easier to 
read :)

I hadn't encountered any of these problems -- I got python-pyqt built against 
the org.openembedded.stable tree (that is, the 4.3.3 version), and installed 
qt4-x11-free-4.4.1 (from angstrom).  They are still binary compatible, and it 
just worked on my Neo, except for the fact that I have to make sure 
LD_LIBRARY_PATH doesn't point to /opt/Qtopia first before starting python (as 
their libraries have the same name, and most of the same functions, but are 
missing some symbols such as QX11EmbedWidget).

That's very nice, Kelvie.
I'm still trying to get a working and safe oetree with qt library inside :).
The first time i tried with the org.openembedded.dev branch and my typical
angstrom configured local.conf file, but it got a compilation error on
uicmoc4-native. After that i tried with the fso openmoko conf file, it
failed again but i noted that the preferred version of qt4 there was 4.3.3
instead of 4.4.1. I remembered that in org.openembedded.stable there was
4.3.3 version, so i tried again with the stable branch. It compiled fine but
did not create all the requested ipk (empty). I managed a bit on the
qt_packaging.inc recipie and finally i got a working qt-oe-tree, i was able
to compile a my application too. I bitbaked the last fso unstable image and
flashed the phone with it, setupped a fake feed server on my oe tree, added
it to feeds on the phone and did opkg update, opkg install qt4-x11-free,
opkg install my-application, and after that i was able to start it adding a
simple DISPLAY=:0.
But i'm not very happy of this as it's not simple and i do not like to mix
different branches.
Please share your experience on this...

In the meantime, I've managed to get PyQt4 working (hooked up against Qt-x11); 
this eliminates the need for a toolchain (or even building apps in general).  
There's another thread about that on this list.

FSO should be the future, while the qtopia phone x11 part of 2008.x will be
ported to FSO or will be substituted by some other apps (Zhone?) i asked on
the list for this but got no answer. It would be nice to know this, but it
seems to be a secret actually.
Due to information lacking, personally (take it with care!) I suppose qtopia
phone x11 will be dropped, for two reason:
1) developing is encouraged on FSO
2) openmoko does not provide an SDK toolchain and OE support for the qtopia
part of 2008.x, for example there are no staging for qtopiamake, qmake and
so on in the openmoko oe build tree... you may always bitbake qt4-x11-free
that provides staging files, but these are incompatible with qtopia-core
library deployed on 2008.x

So it's right to use FSO for your application.
For Michael: i asked that to have some clarification only, as official
Qtopia SDK are incompatible with qtopia-on-x11 and i think qtopia on x11 is
not developed at Trolltech, so qtopia.net will not support it... right?

Well, you may use OpenEmbedded, in the stable tree you have qt 4.3, in the
development tree you have qt 4.4.
FSO is based on the development tree of OE, so you may use the provided
makefile to build your images, qt4.4, and your application.
I was not yet able to do it yet as there are some issues, howewer was able
to build qt 4.3 on the stable branch of OE and some my applications, so it's
may be a little hard or confusing, but you can start developing.
In the meaning, if you want a stable and simple environment to start
developing, you may use the vmware based trolltech sdk, avoiding to use dbus
for the moment, and experimenting qt behavior on a small display while your
OE tree came up (it needs a lot of time!).
In your code you may use some conditional include to read sensors in other
ways than dbus on qtopia, and let the application be compatible with fso,
qtopia, and if openmoko provide support for 2008.x too.

Where may we start a wiki page on this argument (openmoko, openembedded,
fso?)

We would really prefer to use FSO and later SHR, 
we are going to develop a indoor navigation system and perhaps have to add 
some sensors via Bluetooth or I²C and as I understand dbus would be great for 
sensor fusion.
I tried to add the libs as mentioned in the wiki, but I wasn't successful. It 
would be very cool if someone could add the QT4 libs to the toolchain or 
could tell which packages are exactly needed, and I don't know how I can use 
qmake with the toolchain. Until now I have only developed QT with kdevelop.

Hi Michael, and what's about using qt without dbus in 2009.x?
In /opt/Qtopia i found qt4 and qtopia phone libraries, how to build
applications with them?

Good idea! Should be working great.

They should be. If not, we can add Qt/X11 4.x to the feeds.

Not yet. We need to update it to include Qt/X11.

I don't think I can do that soon, but I'll write on my todo list to
create some examples for Qt/X11 and FSO.

Good Speed!

Hi Michael,
Since FSO uses DBus as one of its core technologies, it is toolkit agnostic
as long as the toolkit has DBus bindings. As it turns out Qt has very good
DBus support. In case you haven't already taken a look,

[FSO] How to develop with Qt

[Michael Tansella]

Hi,

We are 2 Students and are doing a research project with the Freerunner. Now we 
need to develop a tool with C++ QT. Because of the nice possibilities with 
dbus we want to do this with FSO. But we dont't know how to do that.

Are there QT libs for OM available yet?
Does the Metatoolchain support it?
Are there any howtos?

We would be very happy if someone could give some hints for the right way.

All the best
Michael
