Imported DLL name and the actual DLL file name have different case

ID PE183 Level WARNING Category Configuration

Cross-executable rule

Description

The executable imports a dynamic library (DLL), and specified the name of the DLL in the letter case which does not correspond to the actual DLL file name case. Importing a library with different letter case will cause issues if the application is installed in a Windows folder which is set up to be case-sensitive.

A Windows administrator can change case sensitivity of a directory using the fsutil.exe file setCaseSensitiveInfo <path> <enable|disable> command. If you prefer to have your executable as compatible as possible, you should take this into account. See more details on case-sensitive Windows paths.

Mitigation

  • Make sure your executable file imports DLL files (which are bundled with the executable file) in exactly the same letter case as actual DLL file names.

Arguments

This rule has the following output arguments:

  • imported_library - Name of imported DLL as it appears in the executable import directory
  • library_file_name - Actual DLL file name
