SVS Viewer crash #414

Open garfieldnate opened 1 year ago

garfieldnate commented 1 year ago

After connecting to SVS viewer and running our ITL/Thor agent for a bit to add all of the scene data to SVS, the viewer crashes with this output in the terminal:

qhull_in = /tmp/qhull_in_irf6ea, qhull_out = /tmp/qhull_out_Aua99e
sh: qconvex: command not found
qhull returned with non-zero status 32512

Soar is able to continue functioning without error, but does not mention in the debugger output that the SVS viewer has disconnected!. If I state the viewer again, it crashes with the same error as soon as I connect to it (presumably because there are already objects in SVS to send to the viewer).

This was encountered on OSX using the 961_svs_glfw_update branch, but was also reproduced on Linux using a very outdated copy of the development branch.

The issue is that the system has to have qhull installed. On Mac, that can be done from Homebrew. On Linux it may be called qhull-bin.

This is an easy fix, but Soar should handled this failure gracefully and let the user know that qhull needs to be installed!
