[SOLVED] J-Link software stopped working in Ubuntu 20.04

Dieselburner · Apr 27th 2020, 9:21am

The title says it all. New Ubuntu dropped support for obsoleted Qt4, and now J-Link tools simply does not work since they have a dependency on this.

FYI: Last Qt4 release was on December 15, 2011, and is unmaintained since 2015. Please consider switching to Qt5, or getting rid of this dependency.

Hi,
Thank you for your inquiry.
That is why we provide all necessary dependencies with the J-Link Software and Documentation Pack.

We will look into this.

Best regards,
Fabian

Hi,
Thank you for making this known to us.
We found the cause of this issue and fixed it.

The fix is part of our next release (V6.72), planned for later today.
It will be available here:
segger.com/downloads/jlink#J-L…twareAndDocumentationPack

Could you please give this version and tell us if it works as expected?

Best regards,
Fabian

I think, SystemView 3.12 has the same problem.
The .deb installs fine in Ubuntu 20.04, but gives this Error:

SystemView: error while loading shared libraries: libQtGui.so.4: cannot open shared object file: No such file or directory

Hi,

Thank you for making this issue known to us.

The issue was not the same, but related.
~~It will be fixed in the next release, planned for later today.~~

Correction: A fixed deb package of the same version was uploaded.

Sorry for any inconvenience caused.

We will consider this thread as closed.

Best regards,
Fabian
