Hi,

Did you check whether you have that library installed on your system ?

DavidXanatos

it did not occur to me that the installer would be dependant on a non standrad library, but now that you said it, ... i could install the lib with apt and it started LOL

DavidXanatos

LOL and it crashed with :
/home/admin/Qt/6.8.2/gcc_arm64/bin/qmake" QList("-query") crashed with exit code 11 standard output: "" error output: "
so not quite good

SGaist

You might be hitting this bug.

DavidXanatos

wonderfull, just wonderfull....and now what LOL

SGaist

Since the other people did not provide the requested stack trace, please do it, it will help.

DavidXanatos

on and how to do it?

SGaist

Since the call to qmake -query crashes, start it using the debugger and once it crashes request the backtrace then you can copy it to post it on the bug report.

DavidXanatos

and how do i start somethign under a debugger on linux without having qt creator up and running?
sorry windows dev here, we just click buttons and don't use console

SGaist

I guess you are running raspbian as your Linux distribution ? If so, you likely have already install the build-essential package which should provide you with gdb.

Then it's: gdb --args /home/admin/Qt/6.8.2/gcc_arm64/bin/qmake -query
Once you are in gdb, just type run and enter. It will call qmake and crash.
Then bt and enter and it should show you the backtrace.

This quick introduction might give you a good starting point.

DavidXanatos

ok done thanks, lets wait and hope for the best

SGaist

Thanks for the help !

The root cause for the problem is that you are using Rasbian, a Debian 12-based distribution, and our binaries are built using Ubuntu 24.04 (our reference platform). And Ubuntu 24.04 has a newer glibc version than Debian12

DavidXanatos

Well but there must be some way around that, cant you link glibc statically into Qt and the installer, AFAIK the Linux kernel tries not to break userspace, so if you link everything statically than that thing should run on a pretty wide range of Linuxes, or not?

SGaist

And you open a new can of worm: what do you do when bugs (especially security issues) are found in glibc ?
