So, I'm trying to package Pure Data for the OpenPandora, however when trying to connect a running jack2 instance I get: Connect: can't connect named semaphore name = jack_sem.1000_default_system err = No such file or directory On the jack side I see: Jack: JackRequest::ClientCheck Jack: Check protocol client = 8 server = 8 Jack: JackRequest::ClientOpen Jack: JackEngine::ClientExternalOpen: uuid = 18, name = pure_data Jack: JackEngine::AllocateRefNum ref = 5 Jack: JackLinuxFutex::Allocate name = jack_sem.1000_default_pure_data val = 0 Jack: JackSocketNotifyChannel::Open name = pure_data Jack: JackClientSocket::Connect : addr.sun_path /dev/shm/jack_pure_data_1000_0 Jack: JackShmMem::new index = 5 attached = 40c47000 size = 432 Jack: JackExternalClient::Open name = pure_data index = 5 base = 40c47000 Jack: JackPosixProcessSync::TimedWait time out = 5000000 Jack: JackPosixProcessSync::TimedWait finished delta = 3112.0 Jack: JackEngine::NotifyAddClient: name = pure_data Jack: JackDriver::ClientNotify ref = 5 driver = system name = pure_data notify = 0 Jack: JackExternalClient::ClientNotify ref = 0 client = pure_data name = system notify = 0 ClientNotify fails name = system notification = 0 val1 = 0 val2 = 0 NotifyAddClient new_client fails name = pure_data Cannot notify add client Jack: JackExternalClient::Close Jack: JackSocketNotifyChannel::Close Jack: JackClientSocket::Close Jack: JackShmMem::delete size = 0 index = 5 Cannot create new client Jack: JackSocketServerChannel::Execute : fPollTable i = 1 fd = 11 Jack: JackSocketServerChannel::Execute : fPollTable i = 2 fd = 14 Jack: JackSocketServerChannel::Execute : fPollTable i = 3 fd = 17 Jack: JackSocketServerChannel::Execute : fPollTable i = 4 fd = 20 Jack: JackSocketServerChannel::Execute : fPollTable i = 5 fd = 23 Jack: JackSocketServerChannel::Execute : poll client error err = Success Jack: JackSocketServerChannel::ClientKill ref = -1 fd = 23 Jack: Client was not opened : probably correspond to server_check Clearly the two are seeing each other, but I can't tell what is going wrong here. Any clues on how to proceed are welcome. cheers, d.
