This appears to be the same as https://github.com/ros-visualization/rqt_image_view/issues/37

Thanks for the report.

@christianrauch Please try the proposed ~fix~ hack from ros-visualization/qt_gui_core#233 and comment here if it resolves the problem for you.

I believe that the issue was fixed upstream with a new release of libmysqlclient21? At least now, even without your PR, I am not getting this error anymore.

Also, as per the comment 8 in upstream bug report https://bugs.launchpad.net/ubuntu/+source/opencv/+bug/1890170, I am getting BIND_NOW for readelf --dynamic /usr/lib/x86_64-linux-gnu/libmysqlclient.so.21.1.21 | grep BIND.

Edit: @dirk-thomas This has been fixed upstream by the release of mysql-8.0_8.0.21-0ubuntu0.20.04.4: http://changelogs.ubuntu.com/changelogs/pool/main/m/mysql-8.0/mysql-8.0_8.0.21-0ubuntu0.20.04.4/changelog

This has been fixed upstream by the release of mysql-8.0_8.0.21-0ubuntu0.20.04.4:

I don't see how a change in mysql can affect this plugin. Afaik it is not part of any of the transitive dependencies.

I am also not sure how they are related, but the upstream issue (https://bugs.launchpad.net/ubuntu/+source/opencv/+bug/1890170) that your PR linked to mentions this and the original issue reported here vanished after the mysql library got updated (https://bugs.launchpad.net/ubuntu/+source/mysql-8.0/+bug/1889851, comment 13).

For sure, I am not facing the originally reported issue any more and I do not require the proposed PR https://github.com/ros-visualization/qt_gui_core/pull/233.

I think the issue does have some relations with mysql. I met the same problem, and I solved the problem with: sudo apt purge mysql-* sudo apt purge ros-noetic-* sudo apt install ros-noetic-desktop-full Now my rqt_image_view just worked again.
