1.I tried to compile QT application Imageprinttest by passing qmake2 using below steps

tamilarasi@ubuntu12:~/Imageprinttest$ /home/tamilarasi/beagle/poky/build-74xx/tmp/sysroots/x86_64-linux/usr/bin/qmake2
QMAKESPEC has not been set, so configuration cannot be deduced.
Error processing project file: /home/tamilarasi/Imageprinttest/Imageprinttest.pro

2.I trying to set QMAKESPEC path using export variable
tamilarasi@ubuntu12:~/Imageprinttest$ export QMAKESPEC=/home/tamilarasi/beagle/poky/build-74xx/tmp/sysroots/x86_64-linux/usr/share/qt4/mkspecs/linux-g++/qmake.conf

3. checking QMAKESPEC location

tamilarasi@ubuntu12:~/Imageprinttest$ export |grep QMAKE
declare -x QMAKESPEC="/home/tamilarasi/beagle/poky/build-74xx/tmp/sysroots/x86_64-linux/usr/share/qt4/mkspecs/linux-g++/qmake.conf"


4.Trying to compile QT Application and getting below error

tamilarasi@ubuntu12:~/Imageprinttest$ /home/tamilarasi/beagle/poky/build-74xx/tmp/sysroots/x86_64-linux/usr/bin/qmake2
