error while deploying to remote device

Mijaz

bash: /home/analog/Desktop/myqt512: cannot execute binary file: Exec format error
bash: /home/analog/Desktop/myqt512: Success

Application finished with exit code 126.

Although I am using same compiler for qt4.8.7 version and that is working fine

@Mijaz You did not cross compile for target device, right?
What is your device?
Also, when asking questions please provide enough information (here you did not even say what device that is).

@jsulm
I am using SDR ad9361 board,
my device architecture is : armv7l

while configuration I have not selected any device because
mkspec /device : there is no device source available for my board.

jsulm

@Mijaz Well, you can't execute x86 binaries on non x86 platforms.
You can check what you executable is doing:

file /home/analog/Desktop/myqt512

@jsulm

Yes exactly, you are right. As my application myqt5.12_test: ELF 64-bit LSB  shared object, x84-64, version 1 (SYSV)
this is not working.

myqt4.8.7_test: ELF 32-bit LSB executable, ARM, EABI5 version 1 (SYSV)
this is working fine.

the configuration process auto select the x84-64 architecture with ELF 64-bit LSB. I had built the qt5.12.5 without specifying the device target because when I try to specify my target then it gets the error .

> collect2: error: ld returned 1 exit status

Now I am trying newly build all these files for qt 5.13.0 with compiler 4.9

ijaz@ijaz-HP-ProDesk-400-G4-MT:~/qt_5_13_configure$  ~/qt_5_13_sources/qt-everywhere-src-5.13.0/configure -release -device linux-arm-generic-g++ -device-option CROSS_COMPILE=~/qt_5_13_root/gcc-linaro-arm-linux-gnueabihf-4.9-2014.07_linux/bin/arm-linux-gnueabihf- -opensource -confirm-license -skip qtwayland -skip qtlocation -skip qtscript -make libs -prefix /usr/local/qt_5_13 -extprefix ~/qt_5_13_root/analog -hostprefix ~/qt_5_13_root/qt5_13 -no-use-gold-linker -v -no-gbm

But this also returns above error

 Makefile:68: recipe for target 'verifyspec' failed

How I can Build for my device "arm" ?

@Mijaz said in error while deploying to remote device:

I have built the qt5.12.5 without specifying the device target

That will not work. You have to cross compile Qt.
Please take a look at what @SGaist wrote in one of your other threads.
