4.6 iOS 64-bit beta

We just upgraded to the latest release (5.0.2p2) and we now get a crashing error when we try to open our online mode.

Code (CSharp):

1.  
2. GC Finalizer (7): signal SIGABRT
3. malloc: *** error for object 0xx1a7342d0: pointer being freed was not allocated
4.  

Also getting some semantic warnings.

We have tried to run this using a mono build and it works fine. We are going to try downgrading the version to patch 5.0.2p1.

Edit: This error does not occur on patch 5.0.2p1

 

Unity 4.6.5f1 / Xcode 6.3.1

IL2CPP

I write like this:

Code (CSharp):

1.  
2. public delegate string[][] getstr_pt (string n);
3. public static getstr_pt getstr;
4.  
5. static public string[][] getstr_1 (string n)
6.     {
7.         string [][] strAsset = new string[1][];
8.         strAsset [0] = new string[1];
9.         return strAsset;
10.     }
11.  

The error occur when we build the app in xcode:

Code (CSharp):

1.  
2. Undefined symbols for architecture arm64:
3.   "_StringU5BU5D_t50_il2cpp_TypeInfo", referenced from:
4.       _pinvoke_delegate_wrapper_getstr_pt_t1303 in Bulk_Assembly-CSharp_10.o
5.     (maybe you meant: _StringU5BU5D_t50_il2cpp_TypeInfo_var)
6. ld: symbol(s) not found for architecture arm64
7. clang: error: linker command failed with exit code 1 (use -v to see invocation)
8.  

 

In 4.6.5p3 after build succeeds in xcode, it is doing a clean. Thus I have to rebuild again.

 

New crash with 4.6.5p3 (RebuildMonoInstance?). Repro project sent: http://fogbugz.unity3d.com/default.asp?699323_olodo4b8fvirrd50

 

I solved this problem, I used a plugin called CloudSystem in my project, this compile error was caused by this plugin.
Removed this then Xcode compiled successful.

 

@JoshPeterson
Thanks. Will wait for p3 then and use p1 meanwhile.

 

@JoshPeterson

Unfortunately I can't upload the project, would the XCode project suffice in this case?

Thanks

 

Hi,

report: http://fogbugz.unity3d.com/default.asp?699733_ad8uitcle1nn16op

A generic-method in generic-class (with multiple type parameters, multiple constraints and interface) throws ExecutionEngineException.

Code (CSharp):

1. public class Test : MonoBehaviour
2. {
3.     void Start ()
4.     {
5.         new TestClass<MonoBehaviour, GameObject> ().TestMethod1 (50);
6.     }
7. }
8.  
9. public interface TestInteraface<T1, T2>
10.     where T1 : MonoBehaviour
11.         where T2 : class
12. {
13.     T2 TestMethod1 (int arg);
14.     T2 TestMethod2<TArg> (TArg arg);
15. }
16.  
17.  
18. public class TestClass<T1, T2> : TestInteraface<T1, T2>
19.     where T1 : MonoBehaviour
20.         where T2 : class
21. {
22.     public T2 TestMethod1 (int arg)
23.     {
24.         return TestMethod2 (arg);
25.     }
26.  
27.     public T2 TestMethod2<TArg> (TArg arg)
28.     {
29.         Debug.Log (arg);
30.         return null;
31.     }
32. }

Build and run this program with:

Mono => ExecutionEngineException (Attempting to JIT compile method while running with --aot-only)
IL2CPP(4.6.5p1) => It works fine.
IL2CPP(4.6.5p3) => ExecutionEngineException (Attempting to call method for which no ahead of time (AOT) code was generated)


Is this a bug or by design?

* If TestClass doesn't implements interface, it doesn't throw Exception, but causes crash.

 

Hi

When I want to build for iOS (Mac or Windows) I get an error from il2cpp in the console.
I was trying to build with Unity 4.6.5p3. Build for 'Universal' architecture & all iOS devices with IL2CPP. Changing 'Striping Level' doesn't help.


Error:

.... [See attachments]

You can find the full error in the attachments.
Thanks in advance.

 

Okay, I understand. I will use workaround call until this problem fixed.

Even then, please fix *crash* bug mentioned above. If the program crashes, it requires a little more time to find out which method call has a problem than case a program doesn't crash.

Thank you for your replies.

 

@JoshPeterson
Edit 2: Found the problem. We were running a post build script which led to some il2cpp generated code to be excluded from the build phase. Thanks for the help, sorry I wasted your time

Thanks

 

We've built some tools that let's us isolate some branches of the code base that doesn't get stripped as desired. This happens inside some dlls that we don't have source for so they're probably potentially referenced. It's critical for us that we get access to blacklist classes.

As with half the people in this thread we're fighting to get below Apple's 100mb limit for iOS, so we're both in a rush and willing to work for it. Am I correct in assuming that if we build a new "/Contents/Frameworks/Tools/UnusedByteCodeStripper/monolinker.exe" we could implement a blacklisting ourselves?

Lucas once referred to this file: https://github.com/Unity-Technologi...inker/Mono.Linker.Steps/ResolveFromXmlStep.cs

Am I correct in assuming the code for the linker is on github? What branch should I try to build?

 

Awesome, but where is the code for the il2cpp linker with the stripping? The Unity trunk is dated 2010.

 

Hi @JoshPeterson
I'm getting this error in 4.6.5p2 ( project doesn't compile on p3 ), looks similar to the issue @Dunmord reported earlier

It's only happening when I'm reloading one of my levels and the logic inside the levels is pretty much the same so I was hoping there is a way around it or track down what is causing it as I really want to submit this weekend.

Any suggestions?

Many Thanks

 

Here we go.. (along with a random selection of smileys that some of the character combinations manage to make up) =O

Thanks

 

@sfjohansson
Quick dirty fix if it's the same problem... Downgrade to a patch before the one you are using or after. That did it for us.

 

Cool, hopefully fixed in next patch then..so I'll try with @Dunmord tip and try p1, cheers for that btw (hopefully p1 still has good metal performance)

Although it's quite interesting that it happens consistently on this one level...when I'm reloading the scene considering that it's not different to other levels with no issues.

 

I managed to track downtime the offender.. if you are using Aron Granbergs A* Pathfinding Project then you can comment out the line 1466 in AstarPath.cs

Code (CSharp):

1. threads[i].Name = "Pathfinding Thread " + i;

and line 836 in RVOCoreSimulator.cs

Code (CSharp):

1. thread.Name = "RVO Simulator Thread";

I also checked on the A* forums and it was safe to comment out the as the name was only used when debugging.

 

hi
unity 4.6.5p3 xcode6.3.2
i have some code like

Code (CSharp):

1.         mesh.vertices = vertices;
2.         mesh.uv = UVs;
3.         mesh.colors = meshColors;
4.         mesh.subMeshCount = subMeshDatas.Length;
5.         for (int i = 0; i < subMeshDatas.Length; ++i)
6.         {
7.             if (i == 1 && subMeshDatas[i].faces.Count == 0)
8.             {
9.                 mesh.subMeshCount = 1;
10.                 break;
11.             }
12.             else
13.             {
14.                 mesh.SetTriangles(subMeshDatas[i].faces.ToArray(), i);
15.             }
16.         }

when i build & run on ios 64 device, it's crashed

20.                 index++;
21.             }
22.         }
23.  

this is a bug? or i use it by mistake

 

Hi,
I'm very sorry if I'm asking same question again. However I've read several times that there is maximum stripping enabled in IL2CPP.
So please let me know for a very basic Unity Project with IL2CPP:
Q1: Does it make any difference to the final built size if I choose a stripping level rather than keeping it disabled
Q2: If Yes, Which stripping level should I choose as I've read in unity blog that compilation might fail using micro-mscorlib,

 

Any tentative date for 4.6.5p4?

 

@JoshPeterson Last repro bug reported May 25th, is still not solved in 4.6.5p4. (http://fogbugz.unity3d.com/default.asp?699323_olodo4b8fvirrd50)

 

@JoshPeterson Apparently the static constructor in SoundManager is causing the problem

 

@JoshPeterson After disabling the SoundManager, I'm seeing the following NPEs which seems to be trigger by date comparing which I'm not calling directly in my code. I'm trying to create a repro project but no success yet.
