Hi, the Poco::Mutex class is a recursive mutex on all platforms (unless there is a bug in the Poco code) so locking the same mutex multiple times within one thread shouldn't be a problem. What happens exactly in case 2, a deadlock? Could you post the stacktrace?
If it solves your problem, I wouldn't mind moving the logging code in the CodeCache constructor to berryInternalPlatform.cpp, where a CodeCache instance is created. - Sascha On 11/19/2012 10:18 AM, Clarkson, Matt wrote: > Hi there, > > following Sascha's recommendations, I changed our project structure to have > multiple applications, with various combinations of plugins using this: > http://sourceforge.net/mailarchive/forum.php?thread_name=3EB93D96-3F6F-4B8F-8293-3F72B7D56D56%40live.ucl.ac.uk&forum_name=mitk-users > > this appeared to work nicely....
