TOPIC:

Applications using 'LRDialogControls'(LazReport dialogs control) on a Debian 13 KDE system installed from scratch do not start and generate an exception:

  $ ./test_fp_error
  Exception at 00007F9BD1708A03: EInvalidOp:
  Invalid floating point operation.
 
Run with gdb:

  Reading symbols from test_fp_error...
  (gdb) run
  Starting program: /media/sf_samfiles/user/etc/app/Dev/2025/my_tests/test_fp_error/test_fp_error

  0x00007ffff54aca03 in xmlXPathInit () from /lib/x86_64-linux-gnu/libxml2.so.2
 

Note. The system is installed to first the console (debian-13.0.0-amd64-netinst.iso), then apt install kde-pasma-desktop libgtk2.0-0t64

However, in the Debian 13 KDE system, which received an update from Debian 12, all applications (compiled with different versions CT 8.4-8.8)
start up and work fine. CT 8.8 is installed on the same system.
  

What could be causing this error and how can I fix it?

Please, give us time to test and report here.

We release Final CodeTyphon Studio ver 8.80

Have fun.

Has the copy-paste issue been fixed in this version? In the previous version, copy-pasting between the CT and the browser often had problems; content from the web could not be pasted into CT, even though it could be pasted into a regular editor like ScitE/Kate without issue.

In this version, have there also been improvements for the docked forms, specifically addressing the inability to delete components on the form using the keyboard's delete key? (CT Widget QT5, Qt6)

Operating System: Manjaro Linux 
KDE Plasma Version: 6.3.6
KDE Frameworks Version: 6.18.0
Qt Version: 6.9.2
Kernel Version: 6.12.48-1-MANJARO (64-bit)
Graphics Platform: X11
Processors: 4 × AMD A12-9720P RADEON R7, 12 COMPUTE CORES 4C+8G
Memory: 11,1 GiB of RAM
Graphics Processor: AMD Radeon R7 Graphics
Manufacturer: ASUSTeK COMPUTER INC.
Product Name: VivoBook_ASUSLaptop X705QA_A705QA
System Version: 1.0

1) Copy/Paste works OK

2) Delete components in docked forms NOT working on Unix OSes.


From our tests Now, Copy/Paste on the new OpenIndianal 2025-10.

I figured out the problem. All applications have always been built in KDE with the package
"oxygen-icon-theme"(Oxygen is the standard icon theme for KDE 4). If there are no icons in the system of this theme
and an exception is thrown in applications that use LRDialogControls.
So the problem is solved by installing "oxygen-icon-theme", although I guess in the absence of a theme
a default theme should probably be used?

Thanks Sir

Upgraded on both Linux Mint and Windows 11 (25H2) witout problems.
Compliments on all your hard work.

Thanks My Friend,
have fun.

CT version 8.8 tested using distribution Debian GNU/Linux 13 with platform GTK2 and QT5, QT6.
Projects (pl_RX, pl_FpSpreadsheet, lz_SQLdb(sqlite), lz_report).

No problems found with QT5, QT6. 

But on the GTK2 stack  an incomprehensible annoying problem with the strange dependence
of LRDialogControls on the "oxygen-icon-theme"(or "gnome-icon-theme") icon theme. 
With QT5, QT6, there is no such dependence on the installed icon theme.

Is it possible to solve this?

Best regards

Any sample project for tests
On Fedora lz_ReportDialogControls seems work OK

The simplest application to illustrate the problem, a form with two components frReport and LRDialogControls.
It starts normally only if the icon theme 'oxygen-icon-theme' is installed (you can also use 'gnome-icon-theme').
Also illustrated with screenshots.

CT version 8.8 using distribution Debian GNU/Linux 13 with platform GTK2

We try on Fedora 43 MATE (XServer) and CachyOS with KDE Plasma 6 (Wayland)
with out problem

My Suggestion is to look your Debian Installation.

 


 


 

Conducted additional research on the problem with an error when launching GTK2 applications in the KDE environment  
using LRDialogControls when icon themes 'oxygen-icon-theme' or 'gnome-icon-theme' are missing.
www.pilotlogic.com/sitejoom/index.php/fo...ply/19221.html#19220

I checked on 4 systems: error (throwing an exception at startup even before the form window was rendered)
occurs on Debian 12 KDE, Debian 13 KDE, MX Linux 25 KDE (is built from Debian 13) systems, but on
Debian Testing KDE(debian-testing-amd64-netinst.iso) all tested applications launched normally.
Applications were compiled with different versions of CT8.3-CT8.8.

I believe the error is caused by the GTK2 dynamic support libraries and has been fixed in new versions of the Debian test distribution.

Best regards

Thanks Sir
have fun.
