Run the executable file built in Ubuntu on Raspberry Pi Ubuntu

[IknowQT]

I copied the executable file built in Ubuntu to Raspberry Pi Ubuntu and ran it, but Permission denied came out and I set the permission?
But the error path is /home/ubuntu/Desktop/DistributionKit/bin/TEST: Permission denied Is this a problem with the path of Cutie or a problem with Linux? Help me

But you have cross-compiled your app on desktop, right? If yes, please see if your TEST binary has correct permissions. For example, look it up in output of ls -aGl. If permissions are wrong, you can change them with chmod and chown commands.

If you have not cross-compiled, then your binary is compiled in x86 architecture but Raspberry Pi uses ARM processor (armhf architecture) - it cannot work, permissions do not matter at all here.

@sierdzio
If the arm64 and amd64 architectures are different for the same Ubuntu, do you need to make cross-compilation?

You are already asking this at https://forum.qt.io/topic/131329/executable-library-permission/6, and I answered there. Please don't post two different topics for the same question, it wastes people's time answering both, or at least cross-reference the other post from each other so that we know.

Yes, like I wrote you in your other thread. Or do you wish to keep asking different people if this is indeed the case because you don't like it?

Yes, cross-compile or compile natively on Raspberry Pi.
