@Asha Please take a look at https://doc.qt.io/qt-5/embedded-linux.html
"we are using linux backend" - which one? -

@jsulm Hi ,Thank you for you guide...
I found which plugin is running on my board,
That is eglfs only,with this link https://doc.qt.io/qt-5/embedded-linux.html
for beagleboneboard my build directory is Qt5,
I got the information in the folder below
cd /home/beagle/Qt5/mkspecs/devices/linux-beagleboard-g++/qmake.conf
in qmake.conf file
QT_QPA_DEFAULT_PLATFORM = eglfs
so now,how to proceed next?
can i change the QT_QPA_DEFAULT_PLATFORM in that file ?
or need to configure with eglfs only?

@Asha said in could not find qtplatfom plugin eglfs:
in the mentioned the path i got it(dont no its currect or not just guessed)
Sorry, I don't get it. What was the output of configure? Did it say eglfs was activated?

I have extracted qt source code,that can be mmoved in QT5 directory,
in QT5/qtbase/mkspecs/devices/linux-beagleboard-g++/qmake.conf file,
the line presene QT_QPA_DEFAULT_PLATFORM= eglfs...
so now i need to configure,
I need to mentioned eglfs in my configure line,so
./configure -platform linux-g++ -release -device linux-beagleboard-g++ -sysroot /home/beagle/BB/sysroot -prefix /home/debian/Qt5ForBBB -hostprefix ~/Qt5ForBBB -device-option CROSS_COMPILE="path" -egl -eglfs -nomake tests -nomake examples -skip qtconnectivitty -recheck-all -v
this is correct?

how do i activate it?
Check the configure log to see what was missing (I'm quite sure that I already suggested that before).

@jsulm Hi,
about eglfs i got this type error,
looking for library opengl_es2

Any ideas ,how do I slove this?

Hi,
Do you have any of these libraries available on your sysroot ?
If not then install the corresponding development package for your target. -
@SGaist thank you for the replay,
but i am not getting the path ,where i have to search those libraries...if you have idea then please let me know the path of those libraries...
/home/beagle/BBB1/sysroot/lib/arm-linux-gnueabihf(is it correct)...

After configuring ,I am getting the errors
ERROR: Feature 'opengles2' was enabled, but the pre-condition '(config.win32 && !features.opengl-dynamic) || (!config.watchos && !features.opengl-desktop && libs.opengl_es2)' failed.
ERROR: Feature 'egl' was enabled, but the pre-condition '(features.opengl || features.openvg) && (features.angle || libs.egl)' failed.
ERROR: Feature 'eglfs' was enabled, but the pre-condition '!config.android && !config.darwin && !config.win32 && !config.wasm && features.egl' failed.
ERROR: The OpenGL functionality tests failed!
You might need to modify the include and library search paths by editing QMAKE_INCDIR_OPENGL[_ES2],
QMAKE_LIBDIR_OPENGL[_ES2] and QMAKE_LIBS_OPENGL[_ES2] in the mkspec for your platform.while checking the config.log file,i understood in my sysroot ,I dont have the libegl packages,how to install those packages? please guide me....
in my qmake.conf file
QMAKE_INCDIR_EGL=
QMAKE_LIBDIR_EGL=this both are empty...what i need to specify there...below is the attachement of my qmake.conf file please go throught that one.....

As any other packages...
On my Ubuntu machine it is:apt install libegl1-mesa-devPlease learn to search for needed packages by yourself:
apt search libegl
