Hi , I have written an small App loading AU. I can Load LinuxSampler AU it works, but with cratches. Other AU works fine... Where is my mistake ? Wenn I will Remove LS from AudioGraph the Plugin crash, other Plugins work without any Error. Who can help me, I'm searching contact to the AU developer!

I Have look on the Source
#ifdef __APPLE__
int InstrumentManagerThread::StopThread() {
// This is a fix for Mac OS X, where SignalStopThread doesn't
// wake up a thread waiting for a condition variable.
SignalStopThread(); // send stop signal, but don't wait
conditionJobsLeft.Set(true); // wake thread
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
return Thread::StopThread(); // then wait for it to cancel
}
#endif

What version of LinuxSampler do you use? Did you build it yourself, or did you use any of the snapshot builds? Can you show us the code in your small app that loads and unloads the AU? I have not seen the crash, neither in AULab, GarageBand nor Reaper. /Andreas |

I got the code off-list. It turned out that the problem was specific to OS X Lion (and probably newer versions), and that Reaper on Lion also crashed when the plugin was unloaded. I've committed a fix for this now. The Mac specific fix in InstrumentManagerThread was: a) not needed anymore in Lion, b) causing crashes in Lion, so I added an OS version check. /Andreas |
