direct reference to protected function

[Aqua1ung]

I just attempted to launch the AppImage on a fresh Linux installation, and here's what I get:

dad@DadsGram~/Downloads $ ./PDF4QT-1.4.0.0-x86_64.AppImage 
warning: direct reference to protected function `_ZNK7QDialog15minimumSizeHintEv' in `/usr/lib64/libQt6Widgets.so.6' may break pointer equality
./PDF4QT-1.4.0.0-x86_64.AppImage: _ZNK7QDialog15minimumSizeHintEv: /usr/lib64/libQt6Widgets.so.6: error due to GNU_PROPERTY_1_NEEDED_INDIRECT_EXTERN_ACCESS

Any idea what I may be doing wrong?

@JakubMelka I think we need a template for issues

What Linux distribution?

How did you install it?

[Aqua1ung]

What Linux distribution?

Clear Linux, Linux kernel 6.10.7.

How did you install it?

Like I said, it's the AppImage that I am using.

[JakubMelka]

@raffaem , what templates?

[Aqua1ung]

Is anyone able to replicate this issue? Or am I the only one affected by this?

Again, I have been attempting to run the AppImage version on some recent Linux 6.10.x kernels. I recall being able to use it just fine on earlier kernels, though I can't really tell you which ones exactly.

Also, are there any plans to build a PDF4QT Docker image?

[JakubMelka]

Hello, @Aqua1ung, no I do not plan to create the PDF4QT Docker image. And I do not understand, why the AppImage is loading system libraries and not those provided in the AppImage. I do not know, how it is possible?

[Aqua1ung]

@JakubMelka, thanks for replying. Is running the AppImage working out for you? Did you try replicating this? Are you getting the same error, or is the AppImage working fine for you?

[Aqua1ung]

@JakubMelka: update: I tried a bunch of other applications packaged as AppImage, and they all work fine, hence I am pretty certain that the fault lies with the PDF4QT AppImage package.

[JakubMelka]

@Aqua1ung, I have tested it on Linux Mint and everything works correctly. I do not know, why AppImage loads the SO libraries from the system instead from the AppImage package.

[Aqua1ung]

@JakubMelka, what Linux kernel did you test it on, if I may ask?

Interestingly, the AppImage seems to be working (to some extent--see below) on my wife's computer (also ClearLinux, though there may be some differences in the installed libraries). Here's what error messages she's been getting:

mom@MomsSpectre~/Downloads $ ./PDF4QT-1.4.0.0-x86_64.AppImage

Note that upon closing the editor window, the process needs to be killed using ^C, as it doesn't exit gracefully!
