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.

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.....

when i tried to install this packages,I got already installed please throught the below screenshots....
sysroot also have those libraries ,here is the attachement
so now what is problem? why it is not enabling....(may be the problem in specifying the path for those libraries in qmake.conf file?)...if got any idea ,then please let me know....

I have the same config.log file for my device.can you please elaborate your this line
Well, you need these libs in your sysroot: /mnt/rasp-pi-rootfs. If your sysroot is a copy of the RaspPi root file system then install the libs there (apt-get on RaspPi).
even i also missing those libraries in my sysroot...i am not using any sd card,i flashed my device...how do i install those

Install on device? Depends on your OS. But didn't we already discussed this thoroughly? If it's a Debian based Linux then you install packages using "apt". How do you create and update your sysroot?

@jsulm I followed the below document ,please go through this one, even he also done with debian,created sysroot....
here is the link https://forum.qt.io/topic/106912/how-to-copy-cross-compiled-qt-binaries-from-one-computer-to-another/13 in the post 13...click here you will get a one pdf(I followed that one) but he did with vnc plugin(export done vnc only),even i also have that vnc plugin and i tried (exported also)but getting the same issue....
I am very new to this,(if i asked any foolish questions then sorry)

Hi,
I tried ,creation and execution of application through command prompt only,created directory
mkdir qws
cd qws
vi qws.pro
TEMPLET=app
SOURCES=main.cppvi main.cpp
#include<QApplication>
#include<QPushButton>
int main(int argc,char** argv)
{
QApplication app(argc,argv);
QPushButton btn("HI");
btn.show();
btn.showMaximized();
}After this gave the command
qmake
the output is:
qmake:could not exec '/usr/lib/x86_64-linux-gnu/qt4/bin/make : No such file or directory
I am fully confused what going,what is the mistake, i cross compiled the qt5 but its showing about qt4....any ideas ?please

Always use the full path to the qmake version you want to use.
Note that your cross-compiles Qt will have qmake built for the host and not the target.

@Asha You can't execute *.o files!
Those needs to be linked together to an executable."arm-linux-gnueabihf-g++: error : .o - please delete everything in your build directory, run qmake again and then build (call make).
Also this error message looks strange - there should be actual file name in front of .o -

No.
What I mean is: delete all build artefacts from previous builds (like *.o files, Makefiles). -

You just need to build again!
"I am not getting any executable file" - yes, because your build fails.
Before I wrote: please delete everything in your build directory, run qmake again and then build (call make).
So again: please run qmake and build. -
