You showed this earlier. The very last word on that line is plain atomic. That is not right for a LIBS/linker line. The earlier -latomic near the end of that link line is fine, but not the bare atomic at the end.

I'm afraid I know nothing about your situation/environment, but that is the cause of the error. Can you track down where that word atomic at the end of that line actually emanates from?

This is what @ChrisW67 was saying in his post above from a few days ago.

I dont know about a single thing of how makefiles work, my apologies. Im going to need some help in order to do that.

Where should i start and what exactly am i looking for?

Hi,

Can you show your .pro file ?

By the way, are you cross-compiling ?
The path to your Qt 6 build contains an armv7 that hints to that.

Here it is, it is unmodified

QT += quick

CONFIG += c++11

# In order to do so, uncomment the following line.

No the program is running on an armv7 machine (raspberry pi 4).

How did you install that version of Qt ?

I used this guide
https://www.tal.org/tutorials/building-qt-62-raspberry-pi

Out of curiosity, Qt has a installer for 64 bit linux right? would it work with 64 bit bullseye ?

SGaist

x86_64, not aarch64.

Since you are using a .pro file, I am wondering whether the mkspec file you are using is faulty. Can you check that ?

ahh glad you have told me, i would have go through the laborious process of formatting a new OS

where can i find this mkspec file? Is the one in /opt/Qt/6.2.3-armv7l/mkspecs folder you mean ? there are so many folder inside though, how do i know which one im using?

SGaist

I think it should be the one for g++. In any case, I would check for stray "atomic" in these files.

drakejest

@SGaist there are so many files so i use this terminal command to do the searching.

Im not really knowledgable enough to know if the atomic under these files are stray, maybe you can tell :)

SGaist

Change qt_lib_core_private.pri

QMAKE_LIBS_LIBATOMIC = -latomic

That is indeed the solution! it does not appear anymore ! Thank you very much for you help. It was very annoying to keep removing it at the makefile everytime i build.

why does this happen though>?

SGaist

Likely a glitch in the file generation process.
