Note : As of 3.10, SuperCollider’s IDE will no longer build on RaspberryPi. This has to do with Qt’s web viewer component. SuperCollider hopes to have a workaround soon, but it isn’t there as of 3.10.2. If you need or want the IDE, run version 3.9.
i did fix both those ellipses occurrences but was still getting an error. could have been cause I was on an unsupported platform…? besides not getting the window, if I leave scide running and walk away the system hangs.
