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"

Automated build system errors (UE4Editor-X.dll missing)


since yesterday we are not able to cook a build on our automated build system. I don't have a clue whats wrong. I think the important part is that (cook-2016.04.21-17.33.19.txt) :

 LogInit:Warning: Incompatible or missing module: UE4Editor-ProjectX.dll
 LogExit: Preparing to exit.

No binaries are checked in, everything is build by the build machine it self. Should the build compile a version of that dll? Because I can't find any section in the log where he is doing that.

Product Version: UE 4.11

As workaround we do now a build step before the packaging/cooking to build the UE4Editor-ProjectX.dll:

C:/Program Files (x86)/Epic Games/4.11/Engine/Binaries/DotNET/UnrealBuildTool.exe ProjectX Development Win64 -project="D:/ProjectX/ProjectX.uproject" -editorrecompile -progress -noubtmakefiles -NoHotReloadFromIDE -2015

Works fine for now.

MartinSE: Your "work-around" saved me big time. I am not sure how this "bug" arises in the first place...

Hey MartinSE-

I'm glad you were able to find a workaround for your problem, however I'm not sure I understand what was wrong originally. Can you provide more clarification of the issue you were having? Also, are you able to reproduce this issue in a new project? If so, can you provide step by step instructions for me to reproduce the issue locally?

I found this post after having the same issue myself. Here are some repro steps:

  1. Launch Unreal Engine 4.15.0.

  2. Create a new project (C++, Basic Code, No Starter Content).

  3. Close Unreal Editor and Visual Studio (saving the solution).

  4. From the project folder, run the command line similar to:`RunUAT BuildCookRun -project="full_project_path_and_project_name.uproject" -noP4 -platform=Win64 -clientconfig=Development -serverconfig=Development -cook -allmaps -build -stage -pak -archive -archivedirectory="Output Directory"`

  5. Result is successful build.

  6. Add gitignore from here: https://github.com/github/gitignore/blob/master/UnrealEngine.gitignore

  7. Create new git repo in project folder.

  8. Commit all non-ignored files.

  9. Perform git clean, removing all untracked files.

  10. Again, run the command line similar to:`RunUAT BuildCookRun -project="full_project_path_and_project_name.uproject" -noP4 -platform=Win64 -clientconfig=Development -serverconfig=Development -cook -allmaps -build -stage -pak -archive -archivedirectory="Output Directory"`

  11. Result is failed build with error mentioned by OP.

I am currently having this issue, and I do not want to have to use the workaround mentioned by OP if possible.

Hi Colin,

Sorry for the delayed response. I ran through your repro steps and the second build in step 10 ended up completing successfully for me. Do you still see this issue in 4.15.3 or 4.16.1?

I finally found the workaround after trying a lot of things out. Note that if you change parameter below things might not work!

  1. First you need to do build:

    "path\to\BatchFiles\Build.bat" "MyUProjectEditor" Win64 Development -WarningsAsErrors "path\to\MyUProject.uproject"

  2. Call RunUAT:

    "path\to\BatchFiles\RunUAT.bat" BuildCookRun -project="path\to\MyUProject.uproject" -noP4 -platform=Win64 -clientconfig=Development -cook -build -stage -pak -archive -archivedirectory="%OutPath%" -utf8output -compressed -prereqs
