Segmentation fault when running online installer

Mark81

Ubuntu 22.04, I've just downloaded the latest open source online installer and here the issue:

$ ./qt-unified-linux-x64-4.4.2-online.run --verbose
IFW Version: 4.4.2, built with Qt 5.15.8.
Build date: Sep 19 2022
Installer Framework SHA1: f29267be97612f7f0bca2666bfe253a761201f6f
Segmentation fault (core dumped)

I'm not sure what I can do to understand which is the issue.

Hi, I also tried the online installer on Ubuntu 22.04, I got these messages:

perhaps if you do the usual Ubuntu Qt incantations and try installing Qt again:
sudo apt install libxcb-xinerama0 libglu1-mesa-dev

(I had to do them to be able to successfully compile my Qt app on Ubuntu 22.04)

Thanks, I tried installing these libraries but nothing has changed unfortunately.
By the way, it finds all the required libraries:

I also did an ldd and compared with yours, the loading addresses differ for all but if ignore them then only one line differ:
I have:
libxkbcommon.so.0 => /lib/x86_64-linux-gnu/libxkbcommon.so.0 (0x00007f4b0601a000)
but you have:
libxkbcommon.so.0 => /usr/local/lib/libxkbcommon.so.0 (0x00007fb89ba11000)

Perhaps that's ypur culprit?

Mark81

Yeah, good shot!
I tried to move the /usr/local/lib/libxkbcommon* files to another location, then I checked that ldd finds the correct libraries and now the online setup works!

I don't know why I have also that set of libraries... but without comparing our setups how one could know it was wrong?

hskoglund

Hi, yeah this shows that it's not only in Windows you'll experience "DLL hell".

How to possibly detect it: in your ldd almost all of the .dll/.so files are located in the /lib/x86_64-linux-gnu directory except ld-linux-x86-64.so.2 and libxkbcommon.so.0.
Perhaps you've installed some other package that as a bonus installs a (bad?) version of libxkbcommon.so.0 in /usr/local/lib.
