Delphi Error – X1026 File not found ‘%s’

Delphi Compiler Error

X1026 File not found ‘%s’

Reason for the Error & Solution

This error message occurs when the compiler cannot find an input file. This can be a source file, a compiled unit file (.dcuil file), an include, an object file or a resource file.

Check the spelling of the name and the relevant search path.

program Produce;
uses Borland.Vcl.SysUtilss;       (*<-- Error message here*)
program Solve;
uses Borland.Vcl.SysUtils;      (*Fixed typo*)

For a .dcuil file, failure to set the unit/library path for the compiler is a likely cause of this message. The only solution is to make sure the named unit can be found along the library path.
