I can't tell for sure but I suspect perhaps you are creating the queue in a different thread from the main one? At any rate it sounds like a thread deadlock issue (hard to track down because different objc runtimes have different locking behaviors when initialising classes). The current released implementation creates the main queue when the class is initialised (it seems to need to do this for OSX compatibility), and does so in the main thread. That means that if yoiu first use the class in a thread other than the main one, it internally asks the main thread to create the main queue before anythign else will happen. Given the runtime oddities, it's probably not a good idea to do it in the main thread rather than the current thread, and I've restructured the code a little to avoid explicitly using the main thread (ie the thread first using the class should be able to create the main quueu itsself). You could try the new code (svn trunk) and see if it fixes your problem. _______________________________________________ Discuss-gnustep mailing list [email protected] https://lists.gnu.org/mailman/listinfo/discuss-gnustep
