Hi,
This is my fifth mail i think and no one still responded me, i'm trying to
start developing apps, using Qt and add Qt support to Yocto.
I've built a image for my Intel Atom based target machine, and added
IMAGE_FEATURES
+= "qt4-pkgs" to local.conf file. It burned succesfuly the image
booted on my target machine and the i've pluged in a usb with a simple qt
app wich would displayed a window and tried to do this:

1. cd to a /usr/bin/qtopia/demos/mainwindow  (for example)
2. (qmake -project)
3. qmake -o Makefile mainwindow.pro
3. (uic ui files)
4. make


 But no succes.

Please can someone show me te correct path to do this?

Instead of just saying "it doesn't work", please say what errors you
get, what doesn't work, and so on.  It's impossible for people reading
this mail to know exactly what's happening.

The "qt4-pkgs" image feature only adds the libraries and demo
applications.  You'll want to add "tools-sdk" to get a compiler, make,
and so on; and also "dev-pkgs" should add all relevant headers.  Then
you'll want qmake, so add this to your local.conf to add the tools:

CORE_IMAGE_EXTRA_INSTALL += "qt4-tools"

When i try

(qmake -project)
says that "qmake: command not found"
the same thing with make
It's there any chance that the Qt isn't added corectly to my image?
Thank you

Hi...
I've tried adding this

CORE_IMAGE_EXTRA_INSTALL += "qt4-tools"

 in order to have the qt4 tools, and now, i made a simple qt4 form
aplication with a label ana a test box, nothing special, just for
test...i first tried to compile the program on my target machine

when i enterd qmake "project" i get this : "QMAKESPEC has not been se.
so configuration cannot be deduced.Error processint file..."

Then i tried to compile the program on my PC, i succeded doing that,
and then copied all the folder to a USB and tried to run the
executable on my target, and got this "./project: error thile loading
shared librarie: libQt5Widgets.so.5: cannot open shared object file:
No such file or directory.

What am I missing?

your PC's SDK seems to use Qt5, Yocto is using Qt4.

ok, so i've uninstalled all the programs ralated to qt4 and qt5, i wanted
to start a fresh install of qt4 SDK, i've found QtSDK v 1.2.1 wich i think
is Qt4 related, I downloaded it from nokia website, installed it, and
creted a simple hello world window...it build and ran succesfuly. But when
i go in the program directori and try to do qmake "project"...it said that
"qmake is not instaled use apt-get install qt4-qmake"...did that, installed
qmake, and tried again to run qmake "project" and nou says: "qmake:could
not find a Qt installation of ' ' "

i've managed to solve the qmake problem i did this:
sudo rm /usr/bin/qmake sudo ln -s /usr/bin/qmake-qt4 /usr/bin/qmake
 After that: qmake -o Makefile myproject.pro
                make
It made me an executable, then i've copied the whole project folder on a
USB stick, mount it on my target and then ran ./myproject...and voila...a
simple window appeared with the clasis "Hello Wolrd!" inside
Thanks a lot for support
