JIT compile error with protobuf-net on MonoTouch/iOS device (iPhone/iPad)

I am using protobuf-net v2 beta r450 (binary distribution) and building a serialization assembly ahead of time using the technique described here:


  • Quicker if-statement: if `variable` is “value” or “value”
  • Compile C++ program on Mac to run on Linux
  • How to mix Qt, C++ and Obj-C/Cocoa
  • Complete solution for writing Mac OS X application in C++
  • Java Developer meets Objective-C on Mac OS
  • Function Pointers in Objective C
  • I create my serialization assembly on Windows and use it in my MonoTouch project. It works under the simulator. But when run on the device, where AOT compilation only is enforced, I get this error:

    attempting to JIT compile method 'ProtoBuf.BufferPool.GetBuffer()' 
    while running with --aot-only 

    The exception occurs when Serialize() is called:

    using (var stream = File.Create(out_file))
        serializer.Serialize(stream, settings);

    Thanks for any help.

    I grabbed the protobuf-net sources (v2 r470). Use of [ImmutableObject] was indeed one of the issues. I submitted a few minor patches to @MarcGravell via the protobuf-net issue list. I have updated my example at http://github.com/t9mike/ProtoBuf1 with this new assembly. Thanks everyone for the responses.

    I had an almost similar problem when working with unity (with protobuf-net and iOS), this helped me:

    Environment.SetEnvironmentVariable("MONO_REFLECTION_SERIALIZER", "yes");
