Re: NSOperation

[Sašo Kiselkov]

Concurrent operations run in separate threads, which don't automatically create autorelease pools (which are thread-local). You should enclose code which runs in a separate thread always in a new autorelease pool.

Hello,

I'm trying to use NSOperationQueue to run a bunch of concurrent operations.  I used the bit of sample code from the Apple documentation for the basic structure, but the code prints some errors and hangs on GNUstep.  Does anybody know what the problem might be?

I get this from my program on GNUstep, it hangs after doing one operation.

I'm using gnustep-startup-0.25.0 on 64-bit ubuntu.  Threads seem to be working just fine.

thanks
