Hello please help !

Here is my situation:

  1. When I run my game in unity everything works great, then when I Build and Run my game starts up and I began to play after about 2 min get this error message (GDB:smile:ata Formatters temporarily unavailable, will re-try after a ‘continue’. (Unknown error loading shared library “/Developer/usr/lib/libXcodeDebuggerSupport.dylib”))
  2. After I disconnect and run the app it crashes on startup

Please help I have done all this work I hope we can fix it. :cry:

Thanks

Hi,
what Xcode / iPhone SDK version are you using?

4

Hmmm… I’m getting the same error. After playing for a couple of minutes, my game freezes with "program received single: “SIGSEGV”. After I press pause/continue in Xcode, I get this:

I’m running xcode 3.2.2, SDK 3.0 and Unity 1.7.

5

In my case it turned out that I had a couple of coroutines that were getting stuck in an infinite loop.

The bug also crashed Unity so I was able to look in the error report for clues.

6

same problem here

7

Having that problem too. Any other ideas on fixing it?

Thanks in advance.

8

I get the same thing intermitently - doesn’t happen every time.

I’m not even sure where to start looking, but I’ll check the coroutines idea, though, I doubt thats it.

anyone else been able to resolve this issue?

9

I now get the same thing with a scene in my game. It just started happening with V3…

So far I’ve tried changing things around but the scene fails to start no matter what I do. It runs fine in the editor.

Any ideas>

10

I don’t know exactly how I resolved it, but I’m pretty sure that a nice reboot did the trick in my case.

Have you tried that?

I also recall running into this or a similar issue during development of one of my previous games. The first scene I loaded right after the game launched was pretty heavy. So, what I did was, simply loading an empty scene first and then calling my game scene from there.

11

One thing I did was to copy my scene, rename the two to make the new one the original, and rebuild, and it works…Not exactly sure why but it does. It’s not exactly what I consider a stable method of doing things though.

Also, the file renaming bug is back. I’ve had script files renamed 4 times now (where it takes out all upper-case letters.)

12

The reboot didn’t help.

One thing, I think I may have narrowed it down to using mp3 file playback in scripts. When I allow my entities to play audio, the scene won’t load. When I turn off audio fields in their public list the scene(s) load…

13

I may be talking to myself but I think I found the problem.

I switched between using a mp3 and using the same sound as a wav file and the error goes away. It looks like it only wants to crash when playing a mp3.

14

I am also getting same problem after I switched my ipod version 3.2 to 4.0. Here the problem is only my game is getting error but all other sample games (done by me ) are working fine.

plz any one help me soon I strucked here.

hey there,
am using the unity beta 5 and publishing to ios 4
It builds, but when my scene loads it crashes with this error. we had an mp3 that we turned off but made no difference. has anyone figured out whats going on?
thanks,
Chris

I had the same issue. My app would start up fine, go through the initial intro scenes, but then crash with the same error message every time I would go to certain scenes. All of the scripting was fine; no null references or anything missed. Ended up methodically removing each object in the scene, building, installing, testing (which I NEVER want to have to do, again), before finally finding the culprit.

Turns out it was a plane I was using to display a 2D texture as a background. The plane had a script to switch between 12 different .tif files depending on the circumstances. The problem was they were all 320x480 so they would fit the screen perfectly. When I resized them to a power of 2 size, it all worked perfectly. No more crashing and no more error message.

Not sure why it made a difference, or enough of one to cause a crash, but it did. Anyone else having this problem might want to go through and make sure all of their textures are power of 2… rather than doing what I did. The only thing worse than deconstructing a scene one piece at a time is having to put the damned thing back together again.

Hope this saves someone from the same hassle.

The reason why one person says its mp3 so you should use WAV and another person says that the textures are not by a power of 2, is because they are both size related. Power of 2 textures get compressed and WAV files are smaller than mp3.

It appears to be a memory problem. I have an iPhone and an iPod Touch, 2nd Gen. apparently, my phone has more memory because the app runs fine on it. But if you are like me and you know Unity but the only thing you know in Xcode is how to push Build and Run, then we have the same problem. :smile:

I dont know where to start, I have tried to reduce the texture seizes but I have not had much luck. I wish there was a clearer way to see how much memory I am using and how much I am allowed to use and what elements are sucking up all the memory so that I can work on it.

I was given a tip that GUI Sucks up memory and my entire game UI was build in GUI so I reprogrammed my game to use GUI Textures with touch input instead of GUI buttons in a GUI function, but still no luck. :face_with_spiral_eyes:

Program received signal: “0”.

If some Xcode guru knows what we need to do step by step, please help. :expressionless:

PS: sorry, I got a little carried away with the smily faces.

I have the same error and currently trying to solve it. In Xcode run the game with the Instruments for Allocation. While the game plays it will show you the Allocations. I will bet All Allocations keep climbing while every other value stays about the same. This makes it hard to pinpoint the process causing the memory pileups. The Leaks Instruments will probably complain of a leak too and throw up blue graph bars for every frame. Some other thread I read today somewhere in the giant pile of data and forum threads I have been through state that it is Mono that is causing the leak to appear but it really isn’t a leak as it has to do with graphics and how mono handles them or something. Maybe if we keep piling on discoveries we can get this thing figured out. Be nice to have some Unity techs on this thread considering a number of us are experiencing the same issue.

"Responding to Low-Memory Warnings in iOS

The virtual memory system in iOS does not use a backing store and instead relies on the cooperation of applications to release memory. When the number of free pages dips below the computed threshold, the system releases unmodified pages whenever possible but may also send the currently running application a low-memory notification. If your application receives this notification, heed the warning. Upon receiving it, your application must free up as much memory as possible by releasing objects that it does not need or clearing out memory caches that it can recreate later.

UIKit provides several ways to receive low-memory notifications, including the following:

Implement the applicationDidReceiveMemoryWarning: method of your application delegate.
Override the didReceiveMemoryWarning method in your custom UIViewController subclass.
Register to receive the UIApplicationDidReceiveMemoryWarningNotification notification.
Upon receiving any of these notifications, your handler method should respond by immediately freeing up any unneeded memory. View controllers automatically purge any views that are currently offscreen, but you should also override the didReceiveMemoryWarning method and use it to release objects retained by outlets or other data objects managed by your view controller.

If your custom objects have known purgeable resources, you can have those objects register for the UIApplicationDidReceiveMemoryWarningNotification notification and release their purgeable resources directly. Registering for the UIApplicationDidReceiveMemoryWarningNotification notification is appropriate if you have a few objects that manage most of your purgeable resources and it is appropriate to purge all of those resources. If you have many purgeable objects or want to coordinate the release of only a subset of those objects, however, you might want to use your application delegate to release the desired objects."

So…it seems that many of the crashes and other issues with shutdowns due to climbing memory can be stopped when the warning is first received. OK. I want to purge the memory and see if that kills the climbing memory problem, but am not sure where to implement it. Since it is Obj-C code it will not be in Unity scripts. Can someone pipe up here and maybe we can solve this issue running through about five current threads. Unity tech? Dreamora? Prime31?

TIA

i had the same error “Program received signal: “0”.
Data Formatters temporarily unavailable, will re-try after a ‘continue’. (Unknown error loading shared library “/Developer/usr/lib/libXcodeDebuggerSupport.dylib”)”

This is the way i get my app running again → Player Settings for iOS → Stripping Level → Switch to Strip ByteCode (iOS only).

I don’t know if what does this Stripping Level… but my app is running again? But also i get a Memory warnig Level 2 Warning now.
So i don’t know… maybe i save some Memory with the switch to this settings and now its running again. But it is no good solution i think.
Because the only thing i canged to my last version… i put many png Grafics for my HUD.

Next step i try to reduce the png grafics to 16 bit?
