How to Build qt object file statically in linux

[arjun kumar]

please help me all qt family
i have created a simple gui application using qt platform
and i have create two file one is main.cpp and other file is project.pro file so i have run qmake command to build the qt project code . its give output object file

i have run this object file in my linux system ,its run perfectly
i have no idea to how to run this object file in my embedded board
i have try to find many solutions but my problem is not solve
i have requested to all qt family to solve this problem

i have written my sequence how to run this file in my linux system

 i have two file main.cpp and project.pro

$ qmake project.pro

this command create a makefile to run make command
and i have run make file

but i need statically linked

You would usually cross compile the application on your host machine for the target machine. But you do not provide much information.

If you really want to do static build (most probably you will still have to cross compile!) you will also have to build Qt statically.

@jsulm how to cross compile
can you give me brief how to cross compilation of qt project binary file linux into embedded system
i have compile this qt project in linux system
can you give me idea about it

@arjun-kumar I don't have exact information for your target device as you do not say anything about it.
You can see how this is done for RaspberryPi here: https://wiki.qt.io/Cross-Compile_Qt_6_for_Raspberry_Pi

@jsulm i have used imx6ul embedded board

I want to know that my qt project has been compiled in Linux and an object file has been generated which is dynamic linked but I need to make this object file statically linked and put it in the board.

@arjun-kumar I don't have to add anything more. As I already wrote: you have to cross compile your app for your target device.
If you enter "imx6ul cross compilation" in Google you will find many links describing how to do this.

Well, it doesn't look like it is one of the officially supported platforms: https://doc.qt.io/qt-6/supported-platforms.html#support-levels-for-target-hardware

Are you running a regular Linux distribution on the embedded platform? Otherwise you have to use boot to Qt (which I don't know anything about). In any case you need to cross compile Qt yourself as well, not just your own application.
