Win32::Ldd - Track dependencies for Windows EXE and DLL PE-files


  use Win32::Ldd qw(pe_dependencies);

  my $dep_tree = pe_dependencies('c:\\strawberry\\perl\\bin\\perl.exe');


This module is an XS wrapper for the ntldd library.

It can inspect Windows PE files and extract information about its dependencies.


The following function can be imported from the module:

$dep_tree = pe_dependencies($filename, %opts);

This function returns a tree of hashes representing the dependencies of the module.

The options accepted by the function are as follows:

search_paths => \@path

Where to look for DLLs. Defaults to the directories in $ENV{PATH}.

recursive => $bool

Indicates whether resolved dependencies should also be inspected for its own dependencies. Defaults to true.

data_reloc => $bool


function_reloc => $bool



The ntldd project.

Other tools providing similar features are the Freeware DependencyWalker (aka depends.exe), or the objdump.exe utility (included with Strawberry Perl).
