Building a qt application

[sarahjohn]

Hi,

Myself trying to build an application in Qt5.It is a simple application creating some PushButtons.But when i tried to run the application I am getting warnings like
QXcbConnection: Failed to initialize XRandr
Qt at-spi: error getting the accessibility dbus address: "Not connected to D-Bus server"
Accessibility DBus not found. Falling back to session bus.
Could not connect to DBus.
Could not connect to dbus.

I have included some files in the INCLUDEPATH of the .pro file.What may be the reason behind this?Please help..

Do you have all dependencies installed? Like libXcb.

What is your operating system?

i am using ubuntu 12.04. while checking for libXcb through
"apt-get build-dep libXcb ",I am getting unable to find source package.

See "those instructions":http://qt-project.org/wiki/Qt5_dependencies.

If that does not work, proceed "here":http://qt-project.org/wiki/Building_Qt_5_from_Git.
