Failed monolinker error on compile

Unity Engine

I am using Unity iPhone pro and am using an external .dll compiled to the .NET 1.1

I have been using this DLL just fine, even on actual iPhone builds.

When I compile I get the following error

I had this problem before and I fixed it by changing changing the parameter order on the method stub. When I had MyMethod(MyEnum someEnum,BinaryReader reader) I would get a similar crash. When I changed the method that was in my external DLL to MyMethod(BinaryReader reader,MyEnum someEnum) it would compile without an issue. None of my methods are overloaded. Compiling worked fine for a while after this change but it has come back again.

I made a test project that also uses my DLL and haven’t been able to re-create the error. I have a pretty large codebase so its hard to track down what is causing the problem but the above issue is how I resolved it before.

Throughout development I am making changes to this external DLL.

This project is committed to an asset server. I have tried downloading the project to a new folder but I get the same compiler issue.

Is there a cache mono keeps of my .dll somewhere that I can try clearing?

The error is coming from Users/joe/iphone-clean/Editor/Mono/PostprocessBuildPlayer.cs:561

Is there some way to determine what script file is being processed at that point, if its a particular script and be able to report that in the error message?

Any input on what may be the cause of this error would be great =)

Hello,
please submit bug report with your project attached to it and drop me a private message with bug number.

In the process of making a sample application I was able to stop the crashing without changing any code.

Before posting I had tried restarting Unity iPhone and my Mac but that didn’t help.

I copied my entire VS 2003 solution to a new folder and compiled it.I then used the DLL generated by that project and the crashing stopped. I went back to my original project and generated a DLL from it again and it worked fine also. So in the process of restarting VS or using a new folder the issue was resolved. The bad DLL in question still causes the compiler to crash even though the dll works fine in the simulator.

Hi Mantas

I have the same exact problem - not trying to run any external dll but pure script.

I will PM you the support number once submitting is done

One thing to keep in mind is that Unity iPhone is .NET 1.1, different things are cut.
The simulator / editor is regular Unity, which is .NET 2.0 + parts of 3.0

Thomas issue was caused by simultaneous use of .NET sockets and micro mscorlib stripping setting. Currently micro mscorlib is not compatible with .NET sockets.

I’ve answered this question on another thread where it was asked:

http://forum.unity3d.com/threads/please-help-for-il2cpp-problem.302670/#post-2321970

Please try to stick to posting a question only once that we we can keep things simpler on the forum. Thanks!
