Arch Linux User Repository

You can build the last version of Beyond Compare v4 I packaged (4.4.7.28397) by doing this:

git clone https://aur.archlinux.org/bcompare.git/
cd bcompare
git checkout dcf8794f1301c9213558b2583a956c04cf2a2135
makepkg -crs

Since you have a license for v4, you might be interested in looking at the upgrade policy at https://www.scootersoftware.com/kb/upgradepolicy .

I hope it helps!

@musikolo Not at this moment but i will let you know if i do.

The only thing i can think of is that i do force Qt apps to go into wayland mode. Was that also the case for this machine? Because otherwise it just runs on xwayland and then i can imagine it would just work without.

Environment:

QT_QPA_PLATFORM=wayland

If you don't do that, theres quite a performance impact, and up until recently caused a lot of issues with nvidia cards; this is now fixed for the most part.

Hi @robindegen,

I finally managed to find a computer with Arch that doesn't have the qt5-wayland package and none of its dependencies. I installed bcompare and it worked well. So, again, you must have something strange in your computer, as qt5-wayland isn't a required dependency, at least, for everyone. If you have a chance to repeat this exercise in another computer, that would be nice to further validate.

Regards.

@Musikolo

Sorry I missed your first message. I tried your 2nd comment.

B: No it does not work.

/usr/bin/bcompare: line 43: 55258 Aborted                 (core dumped) /bin/bash -c "exec -a $0 $EXEC $ARGS > /dev/null 2>&1" $0

C: That works fine

At some point this package was upgraded to version 5, but I don't have the licence for this version.

Is there any way to get the old package for version 4?

@robindegen, I found qt5-base has qpa files. Please try to do the following:

a) Remove qt5-wayland skipping all dependencies:

pacman -Rdd qt5-wayland

b) Run bcomparein a terminal to see if it if works.

c) Restore qt5-wayland:

pacman -S --asdeps qt5-wayland

I was unable to reproduce your issue. Let's see if this shows something useful.

Regards.

@Musikolo When I tried to run it it just core dumped. I then started looking at the shell script itself; set up the LD_LIBRARY_PATH manually and ran BCompare. That then showed that Qt couldnt find a module for 'wayland'. On a hunch i checked if qt5-wayland was installed; it wasnt. Only qt6-wayland was on my system.

If i specifically uninstall qt5-wayland from my system (yay -R qt5-wayland):

~ » bcompare
/usr/bin/bcompare: line 43: 23374 Aborted                 (core dumped) /bin/bash -c "exec -a $0 $EXEC $ARGS > /dev/null 2>&1" $0

If i install it again, the program runs again just fine

Manually running the application (just copy pasting out of the shell script):

~ » BC_LIB=/usr/lib/beyondcompare
~ » export BC_LIB
~ » export LD_LIBRARY_PATH="$BC_LIB:$LD_LIBRARY_PATH"
~ » /usr/lib/beyondcompare/BCompare  

qt.qpa.plugin: Could not find the Qt platform plugin "wayland" in ""
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

Available platform plugins are: eglfs, linuxfb, minimal, minimalegl, offscreen, vnc, xcb.

[1]    23771 IOT instruction (core dumped)  /usr/lib/beyondcompare/BCompare      

Again, reinstalling qt5-wayland makes the program run fine also with that method.

Also note: I dont have kwayland-integration installed. I didn't even know about this package and have been running for a long time just fine without it. I installed it now, just to see if it brings me anything I was missing before.

@robindegen, I'm also on latest KDE wayland. I have kwayland-integration installed which depends on qt5-wayland. However, if I delete it with pacman -Sdd qt5-wayland, I can start bcompare seamlessly.

If you can share more details on what error you're getting, I could look into.

Thanks.

I'm on latest using KDE wayland. I had to manually install qt5-wayland for this to work. It kept crashing otherwise

Everything works fine now, thank you @Musikolo for keeping this package up to date!
