[Error] F2613: Unit 'PngFunctions' not found when compiling Cod.SysUtils.pas

Content

Hello,

I encountered the following error while building the project:

[dcc32 Fatal Error] Cod.SysUtils.pas(21): F2613 Unit 'PngFunctions' not found.

The error occurs on line 21 of the Cod.SysUtils.pas file, indicating that the PngFunctions unit cannot be found. Could you confirm if this file is missing or if it is part of an external dependency that needs to be installed separately?

Thank you!
