could not find qtplatfom plugin eglfs
-
Why are you copying stuff in /usr ? The debian user likely doesn't have write access there.
-
@Asha said in could not find qtplatfom plugin eglfs:
then where i need to copy?
Home directory of the user

Home directory of the user
rsync -avz debian@192.168.7.2:/usr sysroot
Here,I am synchronizing the sysroot from board to computer,
so,Home directory to the user means ,I need to give like this
rsync -avz debian@192.168.7.2:/usr /home/beagle/BBB/sysrootOR
rsync -avz debian@192.168.7.2:/usr /home/beagle

Even if you don't have the Qt folder on beaglebone at same location, you can export the following environment variables on BBB and be able to run your Qt application in it.
export QT_QPA_PLATFORM_PLUGIN_PATH=/home/debian/(Qt folder name)/plugins/platforms export LD_LIBRARY_PATH="/home/debian/(Qt folder name)/lib":$LD_LIBRARY_PATH export QT_PLUGIN_PATH=/home/debian/(Qt folder name)/plugins export QT_QPA_FONTDIR=/home/debian/(Qt folder name)/lib/fontsMain thing you need to check is do you have eglfs as platform in the first place? Because I'm working on a BBB myself, and my application isn't in critical need of eglfs, but normally with BBB sysroot and linaro toolchain combo, you don't get eglfs working. You should check the path
/home/debian/(Qt folder name)/plugins/platformsbefore using any app whether you have a library for eglfs there. If you do, then the commands above will point the Qt application to right folder and it will detect eglfs as platform plugin.@Ketank16 Hi,
can you please show me the, any .pro file,
I am very confused with this target.path file..
I followed this..
here is my .pro file
what i gave target.path, is it correct?
if its correct I am getting the error as shown in screenshot,
for that error solution ,I gave all the rights(rwx) to the /home/beagle/Qt5.13.1 directory then also getting the same error,any suggestions please....
-
@Asha I think the problem is the $$[Qt5] placeholder in the value for
target.pathvariable in your .pro
what if you just make it simple astarget.path=/home/beagle/Qt5.13.1PS: please STOP pasting pictures and just paste TEXT so it's easier for others to reference your posts...

/home/beagle does not exit on my device,
I installed Qt in my laptop(location is: /home/beagle/Qt5.13.1)I copied the cross compiled qt in my device(location is : /home/debian/Qt5),
one more thing,I want to tell
my user password is :1234
I am trying to connect ssh via root,but giving the password 1234 ,I am not able to connect with my board ,getting the permission denied error,
but giving the password "ims1" ,I am able to login via root,
where "ims1" is my old user password ,is this may cause any issues? -

Well, that's the problem: only root has write access in /home.
Why do you use /home/beagle if your user is debian?!
Use /home/debian ... -

Looks like you did not build eglfs support when building Qt

@jsulm
but other platforms like linuxfb and vnc both are enabled while building qt,And I exported linuxfb in my device...
one more ,while building I tried with -eglfs option also but got the error like
ERROR: 'eglfs' already enabled...
-
@Asha What do you actually want to use? eglfs? linuxfb? ...?
Adding -eglfs is not going to help as it is already activated, but your Qt build does not support it. -
@Asha Well, I think I already mentioned this once: you have to know what your device actually uses. Is it X11, eglfs, linuxfb, ...?
