Crash in Mac Editor when Packaging for iOS

Thomas_Ingham · July 8, 2014, 1:59pm

I’m attempting to build for iOS using a project that is known to work on a machine with much more ram. This is the stack trace dumped by the Apple Crash Reporter after firing off a package operation. I will attach relevant message log output in a separate comment.

When attempting to build for Windows (using the Windows editor) the following message output results from a failed package attempt as well:link text

Thomas_Ingham · July 8, 2014, 6:00pm

It appears as though when using Perforce version control, you must check out the Entire project prior to making a build or you get silent failures such as these.

Michael_Noland · July 8, 2014, 7:35pm

Hi ,

Do you by any chance have your Saved or Intermediate folders checked into Perforce? Those folders should be local only, and could cause problems if they are -only, although I’m not sure if that explains the call stack from the Mac crash.

Cheers,
Noland

Thomas_Ingham · July 9, 2014, 11:51am

We do not have Saved or Intermediate checked into version control.

Thomas_Ingham · July 11, 2014, 2:00pm

This is related to the above; same project attempting to build. Unreal Editor Crashes on Project Launch - Platform & Builds - Unreal Engine Forums

Thomas_Ingham · July 11, 2014, 2:01pm

this shouldn’t be marked answered.

ZeroEightSix · July 16, 2014, 3:01pm

Looks like the editor crashed running this:

/Users/Shared/UnrealEngine/4.2/Engine/Binaries/Mac/UE4Editor.app/Contents/MacOS/UE4Editor /Users/tingham/Documents/MartianCraft/tingham/MC_RepublicSniper/MC_RepublicSniper.uproject -run=Cook -MapIniSection=AllMaps -TargetPlatform=IOS -buildmachine -Unversioned -fileopenlog -abslog="/Users/tingham/Library/Logs/Unreal Engine/LocalBuildLogs/Cook.1.txt" -stdout -FORCELOGFLUSH -CrashForUAT -unattended -AllowStdOutLogVerbosity

/Users/tingham/Library/Logs/Unreal Engine/LocalBuildLogs/Cook.1.txt may have more info on what exactly was wrong. Could you attach it? Thanks!

Thomas_Ingham · July 18, 2014, 4:37am

The file does not exist.

ZeroEightSix · July 18, 2014, 2:36pm

Hmm. Would it be crashing that early? OK. In that case maybe you could open terminal and run this command? It should output the log contents to the terminal. I mean this command:

/Users/Shared/UnrealEngine/4.2/Engine/Binaries/Mac/UE4Editor.app/Contents/MacOS/UE4Editor /Users/tingham/Documents/MartianCraft/tingham/MC_RepublicSniper/MC_RepublicSniper.uproject -run=Cook -MapIniSection=AllMaps -TargetPlatform=IOS -buildmachine -Unversioned -fileopenlog -abslog="/Users/tingham/Library/Logs/Unreal Engine/LocalBuildLogs/Cook.1.txt" -stdout -FORCELOGFLUSH -CrashForUAT -unattended -AllowStdOutLogVerbosity

Thomas_Ingham · July 18, 2014, 7:40pm

The cook completed using this command. I was able to package to an IPA (have not gotten it on a device yet to test.)

ZeroEightSix · July 18, 2014, 7:54pm

And you can still reproduce the crash when you package from the editor?

The call stack from Mac says that the engine crashed trying to load your game’s .uproject file. I was hoping that the log from running it would contain some warning or error text that would give us more info. Without it, at this moment, I don’t have any idea what could prevent it from reading this file

Thomas_Ingham · July 18, 2014, 11:20pm

It’s really strange but I was able to complete a build by cooking on the command line and packaging in the editor. the IPA runs just fine on the device. I’m going to tinker around a bit more and see if I inadvertently changed anything else.

anonymous_user_2b03d27c · October 3, 2014, 3:21pm

Hello,

Thank you for your report. We were not able to investigate this on the engine version you reported, but there have been many version changes to UE4 since this question was first posted. With a new version of the Engine comes new fixes and it is possible that this issue has changed or may no longer occur. Due to timetable of when this issue was first posted, we are marking this post as resolved for tracking purposes.

If you are still experiencing the issue you reported in the current engine version, then please respond to this message with additional information and we will investigate as soon as possible. If you are experiencing a similar, but different issue at this time, please submit a new report for it.

Thank you

anonymous_user_e521cf8f · February 14, 2015, 7:09pm

In case anyone finds this in the future:

Make sure you do not have EditorOpenOrder.log accidentally under revision control by P4 or some other write-locking version control (SVN, whatever). EditorOpenOrder.log can be found in your project Build//FileOpenOrder/ directory. It’s easy to accidentally add this to P4 if you aren’t paying attention, because Build/ typically doesn’t have anything else in it except for your application icon.
