Failed monolinker error on compile

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 =)

 

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
