Deploying Qt Application on Linux

@sierdzio thank you for your support, I don't know why this shows diff errors.

Does the AppImage run correctly when you launch it on the original machine (same where you compile and run linuxdeployqt on)?

I don't have any further ideas.

@sierdzio when i run linuxdeployqt , below warning i'm getting

ninetripod@X3399:~/Documents/build-linuxdeployqt-Desktop-Debug/bin$ ./linuxdeployqt /home/ninetripod/Documents/vistaro_04_12/vistaro_build/vistaroQtQuick -appimage -unsupported-allow-new-glibc

i think this is the issue i guess.

yes it has worked correctly.

I don't think gtk style plugins are a problem, they have little to do with OpenGL lib.

@sierdzio i got to know that im building my linudeployqt on latest version of glibc, it should build on older version of glibc. so that it can be run on any newer version glibc as stated in https://github.com/probonopd/linuxdeployqt/issues/340

@sierdzio is there any other method to deploy qt apps on linux other than linuxdeployqt? if yes, could you please give me the steps for it.

@sharath If you read the link you posted you will find these parameters:

-unsupported-allow-new-glibc
-unsupported-bundle-everything
Did you try them?

Oh sure, there are other ways. I don't have any ready-made steps for them, thought.

You can:

create an installer using Qt Installer Framework
create DEB package
create RPM package
possibly create a snap package
possibly create a flatpak package

linuxdeployqt is by far the easiest way.

@jsulm Thanks for your reply.

Yes i did all these step. when i given the flag -unsupported-bundle-everything, i get below error
