Good news first: !!! Pd 0.56-2 plays out audio on SGI Octane with Irix 6.5.22 !!! Used a test.pd script with an osc~ and dac~ object. Audio sounds clean.
Not so good news: I can't load a GUI yet. After forcing AI_PASSIVE the net bind issue goes away but now I get what you had earlier: RIS 12% ./bin/pd X Error of failed request: BadLength (poly request too large or internal Xlib length error) Major opcode of failed request: 18 (X_ChangeProperty) Serial number of failed request: 44 Current serial number in output stream: 46 read from GUI socket: No such file or directory; stopping gui socket 4 - closing audio... closing MIDI... ... done.
IOhannes, Is there something else you did to prevent this issue?
