VSCode build error

Building a C++ project with VSCode on 4.18 fails. System is Windows 10.
Output log here:

I got same error and it was caused by a “space” character in the path to my project.

I had it in:

 C:/Users/Me/Documents/Unreal Projects/GameA/

Had to change this to:


What a bizarre fix - thank you sir!

There shouldn’t be any problems with engine/project paths containing spaces. The default install location for both the engine AND a new project will both contain them :slight_smile: What does look suspicious about your example is that you’ve put your project inside the UE4\Engine\Source directory, which is a little unusual.

Just out of curiosity, what happens if you move your project ourside of the UE4 install directory, say to your documents folder, and try again from there! I do see that MirrorNext’s example is exactly that, which is pretty confusing so it’d be interesting to see if your example is the same!

The path being printed as inside the engine source is caused by the bat file and that is caused by the space in the project folder. So, neither or our projects are actually inside the engine folder. The error log just wrongly prints it like it is.

The bat file is doing a pushd which is causing it so print as it being inside the engine source.

Moving my project to a path without spaces fixed the issue.

Just had the same problem, solved it for me also. Thanks alot!

I also faced the same issue, but not in my Visual Studio. When I tried Generating the Visual Studio Code files by right clicking on my .uproject file of my project, I recieved this error,
