IL2CPP Configuration Namespace Issue in XCode

I am converting a project from Unity 5.4.2f2 to 2017.1.3f1, using Jenkins to automate the build on xcode 8.2.1. Since upgrading the project, the xcode build fails with the error "no member named 'Configuration' in namespace 'il2cpp::icalls::System'" in the file "Bulk_System.Configuration_0.cpp"

On opening the file in the xcode project directly, it shows the error in the function "InternalConfigurationHost_get_bundled_app_config_m1191888808" and more specifically the line

return ((InternalConfigurationHost_get_bundled_app_config_m1191888808_ftn)System::Configuration::System::Configuration::InternalConfigurationHost::get_bundled_app_config) ();

There, the error is described as "No member named 'Configuration in namespace il2cpp::icalls::System"

For reference, I'm building via command line in batch mode using the -executeMethod paramter, which contains a function to set up the following build settings (and then build):

Scripting back-end: IL2CPP
Architecture: Universal
API Compatibility Level: .Net 2.0
Target Device - iPhoneAndiPad
Stripping Level: StripByteCode
Strip Engine Code: true
Target/TargetGroup: iOS

Does anyone know whether this could be due to an error on my part in configuring the Unity project and/or xcode settings, and if so what I can do to workaround or fix it? Or is there an inherent issue with the use of the namespaces there?

 

The issue still occurs after upgrading to 2017.3.0p2

 

Ok thanks, will do. Due to that scale/structure of the project, its not going to be feasible for me to attach it to the report. Is that ok?

 

I have submitted a bug report under 988803 with the Unity project attached

 

If anyone has this issue, I received an explanation from support - It was due to System.Configuration.dll being included directly within the Unity project, which is unsupported. I removed it, and added the reference "-r:System.Configuration.dll" inside an otherwise empty mcs.rsp file in the project root folder. This resolved the issue.

 

no member named 'RtFieldInfo' in namespace 'il2cpp::icalls::mscorlib::System::Reflection'

dev environments:
unity 2018.3.2f1
Xcode 10.1

 

I also have this issue on 2018.3.8f1

 

For me its
"No Member named 'MonoEnuminfo' in namespace 'il2cpp::icalls::mscorlib::System' Bulk_mscorlib_6.cpp

 

I was building the same project regularly until last Thursday when there was some sort of outage on the Apple Developer system that some how retracted my certificates. The AD system came back slowly over a few days and now when I build, I have what appear to be the correct certificates, but I get these errors. I have not explicitly changed anything in the project or the tool chain. I may be mistaken about the last time I built this project, but it was fairly recently. Another simpler iOS project builds fine.

 

Josh, I am uploading the bug report as I type this. I had reinstalled Unity and Xcode but still get one of the errors, now it is consistently just the one re: 'MonoEnumInfo'. It seems like some libraries in my tool chain are mangled/missaligned/ or broken. I there as way to force a clean install of Unity?

 

Hmmm. I did reinstall the same version of Unity and it still failed in the same way. But, after I filed a bug and got notice that bugs in the latest version get highest priority. Is installed the latest Unity and there was no problem. After retesting our apps in the latest Unity (being somewhat timid about Unity updates having gotten some regressions a few years ago) and talking to my team mates about upgrading across the board, I retried the version we had been using and the problem was gone!!!

There must be some things that are preserved between installs, no? For example, if I switch builds, Unity remembers what was open in the prior one and tries to open it in the next one. The problem I and others were seeing seems to have been one of linking to the wrong libraries--so are there any pathways that might be shared or subject to occasional bad updating?

 

Getting Build Error : No member named 'Contexts' in namespace 'il2cpp::icalls::mscorlib::System::Runtime::Remoting' in Xcode10.2 with Unity 2018.3.12f1

 

I also have the same namespace issue when I tried to install the classes in my Native iOS project.

I am using Xcode10.2 with Unity 2018.3.12f1

Have a look at the attached image for more information.

 

I got the exactly same issue with yours

 

Do you have any solution for this issue?, a have same issues, I use Xcode 10.2.1 (10E1001) and the last version about unity 2019.1.1f1.

 

Hi how can I create a new mcs.rsp file?

 

How I am new in this type of development, you could help me more specifically how you solved the problem, I do not know how to create those references and how to eliminate what you say, greetings !!

 

I have fixed this issue by appending "-DNET_4_0" to the OTHER_CFLAGS in Unity.xcconfing file.
see this for more info : https://github.com/jiulongw/swift-unity/issues/31

 

Just create an empty file under Assets fonder in your unity project and name it as "mcs.rsp".
Then paste "-r:System.Configuration.dll" (without quotes).
Now delete the file "System.Configuration.dll" in your unity project.
Then rebuild your unity project.

If this solution doesn't work try the above solution.

 

I'm encountering the same problem with Unity 2019.1.5 (No member named 'MonoEnumInfo' in namespace 'il2cpp::icalls::mscorlib::System').
Adding "-DNET_4_0" in the OTHER_CFLAGS and "-r:System.Configuration.dll" in mcs.rsp did not work for me (I don't have System.Configuration.dll in my project).
I'm using scripting Runtime .NET 3.5 and Api Compatibility Level .NET 2.0.

 

Strangely Unity wont build after i deleted System.Configuration.dll

 

updated to Unity 2019 and managed to delete System.Configuration.dll and add in mcs.rsp but
still has all the "No member named" errors

No member named 'GetAotld' in 'il2cpp::icalls::mscorlib::System::Reflection::FieldInfo:: etc Bulk_mscorlib_9.cpp
and 10 others.

 

no, empty project builds fine

 

did a complete search , didnt find any more System.Configuration.dll..ughhh

 

hmm sorry, dont know what are managed assemblies.

 

Hi, are you able to solve this issue? I am also getting same issue while integrating.
