Receiving Access Violation error

~$ inxi -xxv2
Host: gvj-HP Kernel: 5.15.0-46-generic x86_64 bits: 64 compiler: gcc
v: 11.2.0 Desktop: Cinnamon 5.4.10 tk: GTK 3.24.33 wm: Mutter dm: LightDM
Distro: Linux Mint 21 Vanessa base: Ubuntu 22.04 jammy
Type: Desktop System: Hewlett-Packard product: HP Compaq Elite 8300 SFF

This has happened since upgrading from Linux Mint 20.3 to Linux Mint 21
On starting CQRLog I get the access violation error window pop up. If I press Abort it locks up and I have to force quit. If I press OK, it opens the log and displays the main window and list window then freezes and again needs to be force quit. I have purged and re-installed mysql, mariadb and cqrlog all from the Ubuntu repository but before upgrading I was installing CQRLog from the PPA and wonder if there is any regression error as I can't use the Jammy PPA yet (too new I guess). I sure hope that someone can help as I have discovered how reliant on CQRLog I have become.

That looks like Lazarus/GTK2 problem.
Do you have GTK2 installed or GTK3 that tries to run GTK2 mode ?
I do not know Mint 21 but it can also have GlibC 2.34 already. That also may do something as Cqrlog compiled with GlibC 2.34 does not run with systems that have older GlibC. Perhaps there might be also problems other way round as Cqrlog you are using is compiled with older GlibC.

Perhaps you should try to compile latest Cqrlog from source with your Mint 21 and to be sure to avoid GTK2/GTK3 errors try QT5 version.

Very short guide how to do it:

First install programs for compile using command console:
sudo apt install lazarus git libqt5pas1 libqt5pas-dev
Installing these will install also lot of dependencies so it might take a while.
When all is done get the source code of Cqrlog with:
git clone
If you stared this command while being in your home directory it creates a new folder ~/cqrlog for you.
Then you just change to that directory:
cd cqrlog
And do compile job with:
make cqrlog_qt5
Or if you want to do the GTK2 version use instead just:
And after compile is over install new Cqrlog with
sudo make install

As you already have installed Cqrlog from package all dependencies are there and you can just start using Cqrlog in normal way.

Thank you Saku,

That has worked brilliantly and I have sued the Qt5 version which has very nice graphics. Its great to be back running again.
