About AOT Error at serialization By Unity

Open st0326s opened this issue 8 years ago • 14 comments

Serializing with the following sources, AOT error occurred on the actual machine, I am in trouble because I do not understand the solution method.

How do I fix it?

■Source Code

    public byte[] Serialize(object data)
    {
        // --- シリアライズ
        var memoryStream = new MemoryStream();

        var context = new SerializationContext();
        context.SerializationMethod = SerializationMethod.Map;

        // シリアライズした結果をMemoryStreamに書き込み
        var serializer = MessagePackSerializer.Get<object>(context);
        serializer.Pack(memoryStream, data);

        // バイト配列を取り出す
        return memoryStream.ToArray();
    }

■Source Description param object data is Class Instance

■Error line var serializer = MessagePackSerializer.Get(context);

Sorry for delay.

It is hard to handle object in IL2CPP environment now. In general, you can avoid AOT error to call MessagePackSerializer.Prepare<T>() for each types used in your object tree.

Hello, I got same trouble, How do solution?

unity3d 5.4.5 msgpack version 0.9

About MessagePackSerializer.Prepare<T>()

var serializer = SerializationContext.Default.GetSerializer<T>(); byte[] data = serializer.PackSingleObject(o);

tianwvf avatar Jun 28 '17 07:06 tianwvf

@tianwvf Would you show me actual error message and type?

yfakariya avatar Jun 28 '17 12:06 yfakariya

@yfakariya I am sorry to have trouble but will you tell me a sample source?

Is it in front of line "MessagePackSerializer.Get" that describes "MessagePackSerializer.Prepare<T>() "?

st0326s avatar Jun 29 '17 03:06 st0326s

1.Sample Code var serializer = SerializationContext.Default.GetSerializer(); byte[] data = serializer.PackSingleObject(o);

I seem , when my code decode contain some Array or like arr[] , or too long , it's have the error , Error like first msg:

Yes,
'MsgPack.Serialization.SerializationContext::GetSerializer.Get' for which no ahead of time (AOT) code was generated.

It's my Code . public T MpRead<T>(bool isShowLog = false) { var serializer = SerializationContext.Default.GetSerializer<T>(); // T newdata = serializer.UnpackSingleObject(msgData); return newdata; }

It's My Function: decode Data public T Read<T>() {

    MessagePackSerializer<T> serializer = SerializationContext.Default.GetSerializer<T>();
    //        			
    T newdata = serializer.UnpackSingleObject(msgData);
    return newdata;
}

tianwvf avatar Jul 01 '17 06:07 tianwvf

@st0326s Yes. It is needed to tell IL2CPP compiler that the generic code for the type T is required.

yfakariya avatar Jul 01 '17 06:07 yfakariya

@tianwvf Thank you! I see that your error was occurred of internal generic GetSerializer<T> code of msgpack for cli. It should be caused insufficient MessagePackSerializer.Prepare<T>() call. For example, you might forget call Prepare for "leaf" properties' type of your object tree.

yfakariya avatar Jul 01 '17 06:07 yfakariya

@yfakariya Thank you Reply ! I don't know how to do solve The Error . I try to call MessagePackSerializer.Prepare() MessagePackSerializer.Prepare() MessagePackSerializer.Prepare<UserInfo>() etc...

so I publish ios run still The Error !

tianwvf avatar Jul 01 '17 06:07 tianwvf

@tianwvf did you manage to solve it? I get a similar error when trying to build my Unity game for iOS:

Okay, I've managed to solve it by calling MessagePackSerializer.PrepareType<T>() for all serialized types before MessagePackSerializer.Get

Like this:

MessagePackSerializer.PrepareType<string>();
MessagePackSerializer.PrepareType<MultiplayerMessageType>();
MessagePackSerializer.PrepareType<float>();
MessagePackSerializer.PrepareType<float?>();

///etc...

I suggest adding it to readme since this topic does not seem to be covered anywhere

@DataGreed You are right. I've added wiki and readme.
