Cmake, linux, packing all so/etc files for distribution... qt missing plugins/etc

Dariusz

Hey

I'm a lil lost, I'm trying to collect all assets for my app in 1 palce & reling executable to be relative based so I can zip it up and give away to people. But I got stuck with relinking...

Cmake deploy code >

target_link_options(testApp PRIVATE
        LINKER:-rpath=./
        )
add_custom_target(Deploy ALL
        COMMAND
        ${CMAKE_COMMAND} -E copy $<TARGET_FILE:testApp> ${DEPLOY_DIRECTORY} &&
        cp
        -t ${DEPLOY_DIRECTORY}
\`ldd ${DEPLOY_DIRECTORY}/$<TARGET_FILE_NAME:testApp>|grep -Po "'(?<==>).+(?=\\(0x.+\\))'"\`
        )

Now in root of folder, I have platforms folder.
I also have all .so files in root directory too.

But I end up with this error >

Cannot load library /home/dariusz/CLionProjects/testAppSrclibOutput/Debug/platforms/libqxcb.so: (libQt6XcbQpa.so.6: cannot open shared object file: No such file or directory)

This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.
Available platform plugins are: eglfs, linuxfb, minimal, minimalegl, offscreen, vkkhrdisplay, vnc, wayland-egl, wayland, xcb.

Any hints/ideas?

Thanks.

Hi,

You might be interested by this article form ICS about handling the deployment of application using Qt's installer framework.

Hey
@SGaist thanks for the link & tutorial.
Sadly it does not do anything for me, nor the video.
There is no new build targer when I add cpack. I tried it in past, didn't use as it did nothing.

I have a complex setup, something somewhere breaks something probably. :- ((((

I gotta say, I though that deploying on linux will be easier than windows. But this is just banana stuff. ;/
I'll keep digging.

Running install just gives me >
gmake: *** No rule to make target 'install'. Stop.
Whatever cpack is meant to do, it does not make a new target.

For Linux it depends on what your goal is. If it's package manager integration, more generic, etc.

Maybe a silly question but did you reconfigure your project after adding the cpack bits ?
