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).
