Hello,

I got this exceptions :

It looks like you project might have the Api Compatibility Level (in the Player Settings) set to a value of “.NET 2.0 Subset”. However, one of the assemblies in the project is using the System.CodeDom.Compiler.TempFileCollection type, which is not in the .NET 2.0 Subset profile.

Try changing the Api Compatibility Level value to “.NET 2.0” instead. That might fix this issue.

Hey,

Yup, and the xcode project need to be delete and recreate too.

Thanks

Hi,

It didn’t worked for me…

Do you have any ideas? What do you do with xcode?

5

Installed patch 2017.2.0p2 and it’s still happening!

With 2017.2.0p1 I could just change the directory name but now is not fixing the issue :frowning:

Edit: After a few test disabling/enabling Unity IAP, update Unity IAP, change directory etc now is working on that project and others too… so no idea what was happening.

6

Does this happen to be a FAT32 file system, like a USB thumb drive? We had a bug on FAT32 only that looks similar to this.

7

Are you seeing the same error as @viktouille reported? Or is this a different issue?

8

It was the second error @lefermier reported. “Exception: /Applications/Unity/Unity.app/Contents/il2cpp/build/UnityLinker.exe did not run properly!”

The first time I tried just changing the project folder as suggested here (iOS build error after update to 2017.1.0f3 - Questions & Answers - Unity Discussions), and then disabling/enabling and updating unity IAP as suggested here ( Unity2017.2 : build error : UnityLinker.exe did not run properly! ) and it worked.

9

Hmm, maybe something is wrong with IAP and code stripping. Can you submit a bug report for this issue? It is something which should work properly.

10

I’m on Exfat, does it changes something?

11

I’ve not tried Exfat, but it sounds similar enough to FAT32 that it might be subject to the same bug. Let me know if you are still hitting this issue. If so, I’ll track down the original bug report and determine when it will land in a patch release.

12

I’m still hitting this issue but I gived up trying to resolve it, so I recoded my project from a blank project, and the problem disappeared.
This is the only solution I found and this is what Unity support advised me.

There might still have a file called linker.xml at your Asset folder. When I removed this file, it solved all the issues.

Can confirm, I was having this issue and it turned out to be a link.xml in Assets that was related to Vuforia…I had been working with Vuforia but then deleted the folder and plugins but missed the link.xml file.

15

had the same problem while building to iOS.
prior to this i was migrating project from older version of vuforia to newer one (to 2017.2), and seems some excess files left in the Assets folder as well as “link.xml”. Removing “link.xml” file from project solved this issue for me. also i had set Compatibility level from .NET Subset 2.0 to .NET 2.0. no any service in my project was enabled (nor IAP). thanks for help

16

deleting Library folder from your project folder helps :slight_smile:

17

great ! Had the same error and deleting the linker.xml solved it, thanks !!

18

I have found a solution. Just reimport Unity IAP

19

Windows>Services>Unity IAP>Reimport

Delete all *.js scripts from your project folder. IL2CPP cant compile JavaScript to C++
