Build error 6 is a bit of a generic error message and can be caused by various issues in your code or build environment.
- Check for any syntax errors in your code: Make sure there are no syntax errors in your C++ code that could be causing the build to fail. Look for any red underlines in Visual Studio or other IDEs you might be using.
- Check for missing or incorrect library references: Ensure that all necessary libraries are included and correctly referenced in your project settings.
- Check your project’s log files: You can check your project’s log files located in the Saved/Logs directory in your project’s root folder. Look for any error messages or warnings that might be related to the build process.
- Rebuild your project: Try rebuilding your project from scratch, starting with a clean build. You can do this by deleting the Intermediate and Binaries folders in your project’s root directory and then rebuilding the project.
- Try building a new, empty project: Create a new, empty project and try building it to see if the issue is specific to your current project.
- Check your Unreal Engine installation: Make sure your Unreal Engine installation is up to date and configured correctly.
