Mono scripting backend > Cross compilation job Assembly-CSharp.dll failed

eco_bach · March 11, 2017, 2:49pm

Ok so this is frustrating.
Trying to establish a quicker testing workflow when building Xcodeprojects from Unity.

Mono scripting backend is supposed to be much quicker so I am trying to get to work, However I ALWAYS get a ‘Cross compilation’ error

Unity 5.5.1f1, Windows 10

Is there NO workaround? DO I have to use IL2CPP even for development??

I amusing the Simple Mobile Placeholder project from the Asset Store

Here is my Console

Cross compilation job Assembly-CSharp.dll failed.

So, this is NOT the entire Editor log, but just the portion with the errors. Also, can someone tell me how to read an Editor log. Do you start at the bottom and work your way up? I assume you focus on what is happening just before the error occurs, so does this mean ABOVE the error, or BELOW the error? Any feedback appreciated!

This should work. Can you try it on a Mac machine and see if the same error occurs? Maybe something in this project is causing a problem.

eco_bach · March 13, 2017, 3:19pm

Yes. At least for the Xcode Project build from Unity using Mono backend works on Mac. However now I always get the following error during the 2nd .ipa class compiling step in XCode.

line 3144 in RegisterMonoModules.cpp RegisterAllClasses() function

RegisterClass<Unity::Component>(); Use of undeclared identifier 'Unity'

Op, ok so it seems that when using Mono you need to disable any Stripping. Build-compile times are much better though when compared with Windows.

Windows (Metal, IL2CPP, Stripping, .NetSubset)
XCode build 22 seconds
.ipa compile (using iOS Project Builder) 45 seconds

OSX (Metal, Mono, NO stripping .NetSubset)
XCode build (Symlink Unity libraries) 18 seconds
.ipa compile in XCode 19 seconds
