RVIZ font issue with TF

[capaulson]

Using on Mac OS X. RVIZ runs fine, but when you attempt to add the TF info, RVIZ crashes with:

libc++abi.dylib: terminating with uncaught exception of type Ogre::Exception: : Could not find font Liberation Sans in MovableText::setFontName

Not sure where to start, any pointers?

Hiya,

Could you try applying the following patch? I'm not sure where this file ends up, let me know if you cannot find it.

diff --git a/ogre_media/fonts/liberation_sans.fontdef b/ogre_media/fonts/liberation_sans.fontdef

Actually this patch I mentioned before is not needed anymore - it must be something else. I am not sure where to start either, then, sorry .. I would build rviz with the patches applied (https://github.com/RoboStack/ros-noetic/blob/master/patch/ros-noetic-rviz.patch & https://github.com/RoboStack/ros-noetic/blob/master/patch/ros-noetic-rviz.osx.patch) in debug configuration within a catkin_ws, and then try to see whether you can get any more specific pointers where things fail.

@capaulson: Could you please post the output of rosrun rviz rviz -l? As well as the output of conda list

[Tobias-Fischer]

Found the culprit - rviz is rebulding now. Please uninstall & reinstall and it should work (wait an hour at least for the rebuild)

[capaulson]

Fantastic! Thank you for the very quick response!
