STM32CubeIDE is now run by executing stm32cubeide_wayland official script. If you have issues related to run environment, try to edit /usr/share/applications/stm32cubeide.desktop file and uncomment one of commented out Exec=... lines and comment out currently used one. After making changes to stm32cubeide.desktop run update-desktop-database as root to apply changes.

Discussion about this Eclipse issues is here: https://github.com/eclipse-platform/eclipse.platform.swt/issues/158

@Alex, looks like you found the solution! At least for me.

@bertulli I also had the same problem and found a solution for it here: https://github.com/adoptium/adoptium-support/issues/785#issuecomment-1585740194

The error is apparently caused by a missing directory /tmp/SWT-GDBusServer and creating it fixed the issue. It also fixed the issue for me.

@kumen if this is a general issue with cubeide and not only some isolated cases, it may make sense to add mkdir -p /tmp/SWT-GDBusServer to the scripts calling the cubeide binary as a fix in the package

It seems there is an error with some library, possibly with DBus:

[alessandro@commodoroII ~]$ GDK_BACKEND=x11 stm32cubeide_wayland

Am I doing something wrong? Can I do something to launch the program?

@piernov, thanks. Fortunately, the current ncurses5-compat-libs version is compatible.

Depends on ncurses5-compat-libs after 1.12.1-2, bundled arm-none-eabi-gdb is linked to libncurses.so.5.

After the 1.21.1-3 update my language pack disappeared again :(

New PKGBUILD for STM32CubeMonUCPD is up: https://aur.archlinux.org/packages/stm32cubemonucpd
Can somebody test it, please?

@kumen

@CaptainJack42 try to delete ~/.eclipse/com.st.stm32cube.*.1.12.1.* directory for bringing back marketplace. But all configuration and plugins will be gone. A restore of the configuration and plugins from the previous version of stm32cubeide may be triggered if it exists in ~/.eclipse/.

That worked, thanks a lot for the quick help!

@Sven @sots, my mistake. I'll fix it soon.

Since the latest update (published 13 hours ago, 13-06-2023) the eclipse marketplace is gone for me and my previously installed plugins are gone as well? Is this something ST just did or is this some other issue?

Update: Installing cube IDE from the ST website works and leaves me with the usual marketplace (opening it crashes cubeide with the webkit error if webkit2gtk is installed, if it is removed (with # pacman -Rdd webkit2gtk) it works) and at least my previously installed plugins are still there. For now i'll stick with that version although i don't like it and since the versions can co-exist i might try again if another update drops. I honestly have no idea what is happening.
