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"

No IntelliSense CLion(v)2019.1 UE(v)4.22.1


I am attempting to use CLion for UE cpp development. I can get a project to build through CLion, however, there is no form of error checking or autocomplete.

It appears to lack all proper suggestions. Note for the below code, I have included the Actor header.

I have found and followed every tutorial I can find- that said, I have found the most success with this here jollymonsterstudio.com

I would assume there is some issue with the CMakeLists.txt but I honestly have no clue where to start with that. I am currently using the generated one from the Editor.

Here is the view of the files:

I am running Windows 10 and compiling the project in Debug mode(Release made no difference) and Visual Studio Build Tools as the build solution. I have attempted using the UE4 plugin for CLion with no difference.

If any other info would be helpful, let me know. Any assistance would be much appreciated!

Product Version: UE 4.22

Having the same issue as well. Noticed quite a few people mentioned this being an issue since 4.22 (on the UE Slackers Discord).

I tried CLion versions going back to 2018.1.7 and it did not fix the intellisense. However creating a project with UE4.21 did. Therefore I am fairly sure it is a regression on the Unreal (CMake) side rather than with CLion.

We should gather more detailed findings if possible to report it over at the UE4 issue tracker.

I had the same issue (also running 4.22). I'm running in Linux so this might not apply to you.

Basically I removed the directory


then re-built the project in CLion. That resolved the intellisense issues for me. Not sure if there is an analogous solution for Windows.
