IL2CPP build error on 5.5.0f3

[quxn6]

Hello.

I had used 5.4.x , building IL2CPP was good.
after updated 5.5.0f3, error occurred.

I tried cleaning library folder. using other machine to build, reinstalling unity5.5.0, but not working
other migrated project also has same problem.
but test project made on 5.5.0f3 built successful.

I couldn’t understand why. am i missing some packages?
please help me.

Unfortunately, there was a bug with Android/IL2CPP in 5.5.0f3 which prevents the real error message from being displayed in this case, so we don’t even know what the problem is here. Can you try Unity 5.5.0p1 or later? That bug was corrected, so we should be able to get a better log message with information about the actual cause of this problem.

Thank you for your quick answer.

Thanks for the more detailed error! This is a known issue in 5.5.0f3 with the Unity Ads integration and Android/IL2CPP. We have corrected this in the 5.5.0p3 patch release. Please try that version.
