Qt program have no text and i haven't font error

sorry if my english isn't perfect but my first language is french.
My problem is I have a cross-compiler on my window for raspbian and i finally did it, but when i execute the program on my pi the widget on window has no text and i don't have a close button. Someone gave me a code that works perfectly on his raspberry pi and i have the same result. With both codes it's the same result: just the basic window with a push button "test" written over it. So I know that my issue isn't my cross compiler but is on my pi. I tried to uninstall qt5-default package,reinstall it and upgrade all packages, but isn't effective. i tried to run linuxfb plugin with this command -./myprogram -platform linuxfb but i have the graphical bug... take a look at this picture.
my program it's on the left corner
I have also posted on Qt forum, but the reply time is very slow. it'll have been three weeks that i tried to find the issue. if anyone can provide a solution or an idea for this problem i will take any suggestions.
Thanks for reading this message.
Kuba Ober gave me a solution to solved it take a another microsd reinstall a raspbian img with qt5 and it's work!!! but what is exactly the issue i don't know but this solution work.
I know that my issue isn't my cross compiler but is on my pi
That's unlikely - it's easy to check: download a fresh Raspbian image to an SD card, boot it up, and try your code out.
You forgot the more likely reason: you probably have built a non-fully-functional copy of Qt. I bet it won't work on anyone's Raspberry Pi, including your friend's.
Your issue is actually the --platform plugin you are using, linuxfb won't have any Windows borders because it's writing directly to the frame buffer, not to the X server. You need to use xcb.
And don't run it as root or you are likely to loose your DISPLAY environment.

I cannot find sched.c in ubuntu

I want to learn real-time scheduling, so our professor asked us to change sched.c. But I even find it. My OS is ubuntu LTS 12.04. I searched it online. Someone said there is no sched.c in ubuntu. Is he right? What file does ubuntu use to schedule? tick-sched.c? BTW: I am a linux rookie, could some tell me where I need to start? Thanks a lot.

Making Kinect and Processing work on Mac.

I am trying to run some of the examples with running Kinect and Processing together
http://www.shiffman.net/p5/kinect/
I have installed everything in the directions. However, when I run the processing code, it says "Kinect not found". I have done nothing except for:
1. install processing
2. install relevant libraries
3. connect kinect to computer
I have a feeling I am missing something obvious here. I am just confused because this particular library only works on Macs, but the Kinect generally works on Windows. Any guidance towards making my Mac recognize there is a kinect connected to it would be great. Thanks!
You can use a Kinect on OSX, Windows or Linux depending on the drivers/SDK (e.g. Kinect for Windows will only run on Windows 7 and up, but OpenKinect/libreenect or OpenNI will run on the above mentioned).
I'm not sure if you need to install the libusb-devel driver or not, but you should give that a go using MacPorts for example:
sudo port install git-core
sudo port install libtool
sudo port install libusb-devel
Also the Processing OpenKinect wrapper is a bit limited. You can't get accelerometer data for example. Other than the depth,RGB,IR streams with OpenNI also supplies, motor control is the only extra feature. On the other hand OpenNI also comes with hand tracking, gestures, skeleton and scene detection, etc. I recommend giving SimpleOpenNI a go.

Great difficulty setting up Ajax Push Engine(APE) in my Virtual Box

Is there any kind fellow windows user who had faced similar problems that can provide me some concrete ways in setting up the APE?
From their homepage: http://www.ape-project.org/wiki/index.php/Setup
Also from their google group: http://groups.google.com/group/ape-project/web/installing-ape-on-ubuntu-9-04
The second is specific to ubuntu 9.04 so fi you are using virtual box you could install ubuntu 9.04 and go through this guide.
