Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

I'm using UE 4.12.5 and build my project (only blueprint) for iOS on a PC in development mode (by the book)

  • I'm able to build the project using the project launcher :

  • But NOT able to build using Custom Launch Profiles with the same parameters, I got this error message :

alt text

 Program.Main: ERROR: AutomationTool terminated with exception: AutomationTool.AutomationException: Unabled to build Project C:/Program Files/Unreal Engine/4.12\Engine\Source\Programs\IOS\MobileDeviceInterface\MobileDeviceInterface.csproj. Project file not found.

  • Could you please upload your full error output logs as a .txt file for me?

  • Are you able to package by using File > Package?

  • If not, could I see those logs too?B

Sadly the logs do not provide me enough information. It does say that the project file is not found. Are you telling it to package for that specific project when you're in UFE? Could you show me screenshots of your set up, so I too can try to package the exact same way you are?

Thank you.

Finally I decided to build my project on a Mac via rsync, using the UE4 source on GitHub I'm now able to build the project with custom launch profile.

Thanks for your help Best regards Stéphane

This happened to me after I removed the InstalledBuild.txt from Engine/Build. I dont know if it has something to do with the problem but it got fixted after I restored it.
