Ipscan not working in Bullseye

[feadog1]

Angry ip scanner not running under bullseye rpi-os rpi4.
Error message " failed to load native code. Cannot load 64bit swt libraries on 32 bit JVM"

While I know bullseye is not fully supported, it would be nice to see this working as in Buster.
Thanks

Is your bullseye OS 32-bit or 64-bit?

[feadog1]

Its 32 bit armv7l. Rpios Buster upgraded to bullseye.

Hi! I got the same problem on a freshly installed Raspberry Pi OS Bullseye 32-bit.

Hello, same here, I have a fresh install and an update from Buster both same result as the first comment here. Any updates / solution? thanks!!

I got it working, see angryip/ipscan#322 (comment).

For anyone who urges to use Angry IP Scanner on Bullseye ARM32, enter this command for a temporary fix:

cd "$(mktemp -d)"
wget http://ftp.us.debian.org/debian/pool/main/s/swt4-gtk/libswt-gtk-4-java_4.10.0-3_$(dpkg --print-architecture).deb http://ftp.us.debian.org/debian/pool/main/s/swt4-gtk/libswt-gtk-4-jni_4.10.0-3_$(dpkg --print-architecture).deb http://ftp.us.debian.org/debian/pool/main/s/swt4-gtk/libswt-cairo-gtk-4-jni_4.10.0-3_$(dpkg --print-architecture).deb
sudo apt install ./*.deb
sudo apt-mark hold libswt-cairo-gtk-4-jni libswt-gtk-4-java libswt-gtk-4-jni

@theofficialgman Do you know where we can report the broken SWT packages to Raspbian?

[theofficialgman]

the launchpad is the official place to report it https://bugs.launchpad.net/raspbian

you can see what process they want you to use here: https://www.raspbian.org/RaspbianBugs

I guess if the debian buster ones work then its actually a bug with raspbian packages for it. the version for those packages is the same in the raspbian repo as the debian buster repo http://archive.raspbian.org/raspbian/pool/main/s/swt4-gtk/ , so its not that they are out of date or anything

[theofficialgman]

edit: oh I see you are referring to an issue only occurring on bullseye, the debian bullseye packages for swt are at version 4.17 while the raspbian bullseye packages are still at 4.13, so they are out of date, it might just be a matter of updating those in the repo and then everything might work

[feadog1]

Great work and thanks for the temporary fix.

Maybe SWT on 4.17 is not supported on armhf, since there doesn't even have armhf packages on https://packages.debian.org.

Thanks for the temp fix cycool29!! it worked for me when I apply the fix on a system where Angry ip scanner was previously installed, but now I have applied the fix before installing it and it doesn't let me install it, stating:
Failed to install file: A package could not be found that allows the action to complete...

Maybe SWT on 4.17 is not supported on armhf, since there doesn't even have armhf packages on https://packages.debian.org.

I checked the ubuntu launchpad to see if armhf was still in their buildscript and it is, but its failing on anything newer than 4.18 (no ubuntu release uses 4.17). you can see the buildlog from the 4.18 and the errors it is encountering on armhf here: https://launchpadlibrarian.net/557787289/buildlog_ubuntu-hirsute-armhf.swt4-gtk_4.18.0-2_BUILDING.txt.gz

in both cases, on ubuntu and debian, the Debian Java Maintainers are the ones responsible for this package
https://launchpad.net/~pkg-java-maintainers
their email for contacting is here: pkg-java-maintainers@lists.alioth.debian.org

[theofficialgman]

did more searching and it looks like they are already aware:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=962915
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=960769

the issue is because upstream stopped supporting 32bit alltogether in 4.10 for ALL eclipse projects. it managed to continue building just fine until the 4.15 release when code was changed and 32bit building actually broke

[theofficialgman]

raspbian bullseye is basically supplying 4.13 on armhf even when its unsupported upstream. they should either revert to 4.10.0-3 on bullseye, or make sure to apply this patch to their 4.13 build: https://sources.debian.org/patches/swt4-gtk/4.10.0-3/0004-Use-is64-defined-for-build.patch/

and yes I checked, raspbian bullseye IS missing that patch on their build for 4.13.0-1, it might not be possible, but it definitely won't work without it at all (as you have seen)
