IL2CPP split binary

I have managed to get the project built and run with IL2CPP turned on. But only if "split binary" is not enabled. Is this a known issue?

 

Just wanted to bump this as I am still unable to get IL2CPP working if "Split Binary" is checked on. Otherwise it works perfectly. The logcat of the crash is here:

I got mine to build, but regardless, mine gets a SIGSEGV... Likewise, I'm having a similar problem.

EDIT: Oops! forgot to state that mine wasn't split OBB!!!

 

Yes it's now fixed. Thank you.
Are we recommended to use IL2CPP for Android or is it safer to stick with mono. What's the advantages?

 

From what I've gathered, IL2CPP uses native code of which is a lot faster than dalvik code.

The disadvantages are mostly because the support for android is so young... For me, it's crashes on loading any scene... (well, the first one loads, but any more past that gets a SIGSEGV in the console!) For other people, it's different problems. In either case, for a serious project, I recommend sticking to mono 2x for now until everything's fixed up. (5.2.3 might fix some things to do with IL2CPP android, would have to check the release notes)

 

I presume it's the one I sent a few weeks back from the bug reporter... Either way, thanks for this.

I haven't tried using latest unity yet, but I may as well check it out if it's apparently fixed up unintentionally.

Also, unless you can't share that here, what have you found so far in my bug report?

EDIT: I also had an idea... going to test it and report back.

 

Ok, my test results with IL2CPP...

Attempt to play a movie file with handheld API (In case that was causing SIGSEGV): Works.

Attempt to load a different scene (Application.LoadLevel()): this came up in logcat:
(Check IL2CPP crash.txt, it kept screwing up when pasting into a code window here... )

Attempt to load using LoadLevelAsync: Same result

This was all done in the most minimalist scene possible, i.e. empty scene with skybox and camera.I did the loadlevel test by directly reloading the first scene.

This is the exact behavior that my working project does when switched to IL2CPP.

To Unity Tech Developers: you probably have a similar log in my bug report already, but in case you need it, attachment's there to look at.

 

Thanks which Unity Version are you referring to that IL2CPP is working well now?
Slightly off topic, any chance that the c++ code could not retain original class and method names? I recall still see lots of references of original class/reference names in assembly dump.

 

There are some players who like to reverse engineer the game. When it comes to IL2CPP they can do it with tools like IDA to easily find human readable functions names, strings etc, modify it and make it unfair for other players of the game. If there are no longer human readable functions/classes/strings etc, it will be much harder to simply find a function like "getHealth" etc and do trial and error value modding. Instead of going straight to "getHealth" they'd have to try a million other methods and hope to get lucky to get anything done. Right now it's too easy. It's not going to stop someone very determined, but it will deter the average enthusiasts.

 

Thank you. That makes sense.

 

Is there a way we can strip them now if we want to (external tool?)

 

Hey @Yury Habets

Is there a way we can strip them now if we want to (external tool?)

 

I'll have to file it again I think... it happened to me again today!

EDIT: And what do you mean by device? the one I ran the game on, or the one I sent the bug report from? If you mean the build target... Will mention that in the bug report I send out. (again... )

EDIT2: How to get the case number? I haven't had to report bugs much in the past, and have no idea how to do this...

 

@Yury Habets: Got the bug number: Case 757384

 

@Yury Habets: Bump

 

These details should be part of "the" bug report "faq"

 

Sure, I can get the "fingerprint" for you. (I like that word for a firmware identifier for some reason. )

As for why it doesn't look familiar, it's a chinese tablet, it isn't common to find that one now. (The latest one's a Pendo Pad 7.0 or something, and runs 4.2, not 4.0.3 like mine)

Oh yea, and getting the fingerprint might take a while (I'll have to boot into windows again... )

 

Here's the fingerprint for teh Pendo Pad 4.0 (PP4MT-7):
sc/crane_PP4MT_SC3037/crane-PP4MT-SC3037:4.0.3/IML74K/20120316:user/release-keys

And I can test the example project on my mum's phone (a Samsung Galaxy J1) if needed.

EDIT: Build fingerprint for Samsung Galaxy J1 (if needed):
samsung/j1nltedx/j1nlte:4.4.4/KTU84P/J100YDXU0AOC1:user/release-keys

 

Damn... it looks like the crash only happens on a Pendo Pad 4.0! I'll have to check I got the test right though.

 

When will the Android IL2CPP be ready and stable?
Is there any way to strip the symbols using a Mac? We really need to remove the debug symbols.

 

I looked at the Bulk_Assembly_CSharp cpp files in ios build xcode. I can see all the original function names and class names still in there. I wonder once compiled will the function names still be searchable by software like IDA?

 

Ok, looks like I've confirmed my bug's device specific, I'll have to debug myself and figure it out... Does anyone else here have an Allwinner A10 device they can test on? Maybe the allwinner architecture doesn't like something IL2CPP's doing.

 

Also OMAP devices don't play well too

Damn... that looks like the garbage collector's crashing! Is that even POSSIBLE?
Yury, you might wanna look at this...

EDIT: One more thing too; I can definitely confirm my crash exists inside native code. (It mentions il2cpp.so on the top of the list!)

 

Would be nice to see more focus on il2cpp android But it seems it's almost a convenient side effect from the mandatory ios 64 bit upgrade

 

That's one reason I like about unreal because they support c++ from the ground up. But their license is actually really crappy compared to unity, despite what most people on here think.

 

Agreed, I stay away from them for that reason. (That, and you need a mammoth of a machine to run unreal engine's editor!)

 

I can't confirm what your avatar is, a cute plush mouse?
Have you given Shiva a try? Before I started Unity I was interested in that, but I never hear people talk about it. If I had time I'd try it myself but time is a sparse these days.

 

No. It's actually my hedgehog self...

 

Last thread bump, I'm back to say my issue was fixed; as of 5.3.4p5, the Pendo Pad's able to run IL2CPP builds properly! For those who had similar crash issues to me, go check your devices against this version.
