Unfortunately I've recently come across a problem when running the startBristol script. I switch between two kernels (CK for desktop and RT7-CK for real-time music work). When within the CK kernel the program runs as expected, but when in the RT7-CK kernel, as both user and root, the program crashes and outputs this message with any selection of synth, audio driver and port: [root@myhost bin]# ./startBristol -jack ./startBristol: line 188: [: too many arguments spawning midi thread parent going into idle loop midi sequencer Problem with bind Could not open control listening socket: 0 No controlling socket available: anticipating MIDI connected to :0 (814b2f0) Error opening control device, exiting midi thread display is 1280 by 800 pixels Window is w 1280, h 800, d 24, 0 0 0 Using TrueColor display masks are ff0000 ff0000 ff0000 Initialise the arp2600 link to bristol: 8153348 hostname is localhost, bristol port is 5028 ./startBristol: line 272: 3877 Segmentation fault brighton $* -engine [root@myhost bin]# parent exiting [root@myhost bin]# As a Linux novice I do not know what could cause this. I changed the permissions of the entire bristol-0.9.5 directory to '777' after my preliminary tests, but this did not help. I have not experienced problems with other audio software using this kernel. If anyone could give assistance then I would be extremely grateful.
