“Fatal: F1027 Unit not found: ‘System.pas’ or binary equivalents (.dcu)”
Posted by jpluimers on 2020/08/25
If you ever get a “Fatal: F1027 Unit not found: ‘System.pas’ or binary equivalents (.dcu)” – Google Search, then it is likely because you:
- build from a script
- build use a user that has never ran the Delphi IDE
This is common for unattended builds (like build-automation).
For each run, the Delphi IDE will save an EnvOptions.dproj with global settings.
Since build scripts should not rely on global settings, you need to ensure those are in your project settings.
