Fix C++ build errors
Paste a build error and Dola finds the cause in your source files and edits them to fix it, explaining what went wrong.
Last updated 10 October 2026
Status: Live
When to use it
Use it when an Unreal build or Live Coding run fails.
Example prompts
Type requests like these in the Dola chat:
- The build fails with this error: (paste). Fix it.
- Why does my UPROPERTY not show up in the editor?
What you need
- The Dola desktop app, signed in, with your Unreal project attached
Safety notes
- Dola edits source files; you compile in Unreal and review the result.
- A rollback from chat keeps Dola's source file edits; revert those in the app's Changes panel (Ctrl+E).
