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"

GenerateProjectFiles not generating directories, definitions, classes

I am on a Linux machine with UE 4.11 installed, built it and can run the editor with no problem. I have installed it in the Download folder:


I am following this tutorial for setting up a cmake environment to do my C++ development in CLion. If I understand the tutorial correctly, I am supposed to have a template game first. I tried going for a blank c++ project and called it BasicCodeNoStarter. It is stored in:

 /home/me/Documents/Unreal Projects/BasicCodeNoStarter/

I then go on the terminal and:

 cd Downloads/UnrealEngine/ && ./GenerateProjectFiles.sh -cmakefile -game -project "/home/me/Documents/Unreal Projects/BasicCodeNoStarter/BasicCodeNoStarter.uproject"

When I do that, I get:

 UnrealBuildTool Exception: ERROR: Directory '/home/me/Downloads/UnrealEngine/Engine/Source/Projects/BasicCodeNoStarter' is missing 'Source' folder.

It looks to me like it is creating a directory inside my engine installation and failing for some reason. Although I had files in the source directory of my project:

 ls "/home/me/Documents/Unreal Projects/BasicCodeNoStarter/Source/BasicCodeNoStarter"
 BasicCodeNoStarter.Build.cs     BasicCodeNoStarterGameMode.h     BasicCodeNoStarter.cpp
 BasicCodeNoStarter.h     BasicCodeNoStarterGameMode.cpp

I tried adding a class MyActor there and after I did that, Unreal editor compiled the project automatically but that does not change anything. Running GenerateProjectFiles.sh still returns the same error.


I managed to get it to build by manually creating the source folder:

 mkdir /home/me/Downloads/UnrealEngine/Engine/Source/Projects/BasicCodeNoStarter/Source 

and the CmakeLists.txt gets generated for me and I no longer get the error. However,

-The directory /Engine/Source/Projects/BasicCodeNoStarter/Source does not get populated.

-The c++ class that I had added to my project through Unreal's IDE, namely MyActor, is nowhere to be found. It is not in the source directory ^ nor is there any sign of it in the CmakeLists.txt file.

  • include_directories and add_definitions both have empty argument lists in the cmake file.

My guess is that I am missing a step before running the build tool. Any idea what?

Product Version: UE 4.11
