The latest version of Qt 5.4.1 opensource is not supporting virtual frame buffer ie qvfb.
I am getting the following error when I tried to configure using qvfb.

./configure -platform -qvfb -prefix /home/user/buildroot/qt-5.4.1/qt-embedded-qvfb/qtbase -opensource -nomake tests

The specified system/compiler is not supported:

/home/user/buildroot/qt-5.4.1/qt-embedded-qvfb/qtbase/mkspecs/-qvfb

Please see the README file for a complete list.

Could any one who tried with Qt 5.4.1 could you please provide the steps to configure for qvfb.
I was able to do with qt 4.6.1 as per the documentation given here
