An open-source modern Dependency Walker

Overview

Dependencies is a rewrite of the legacy software Dependency Walker which was shipped along Windows SDKs, but whose developement stopped around 2006. Dependencies can help Windows developers troubleshooting their dll load dependencies issues.

Releases

v1.8 : Add x86/x64 variants for Dependencies

v1.7 : Add CLI tool “dependencies.exe”

v1.6 : Add appx packaging

v1.5 : Support of Sxs parsing Support of api set schema parsing API and Modules list can be filtered

v1.0 – Initial release

Installation and Usage

Dependencies is currently shipped as a binary (no installer present). Just uncompress the archive and click on it. Since the binary is not signed, SmartScreen might scream at runtime. Dependencies also bundle ClrPhTester.exe , a dumpbin-like executable used to test for non-regressions.

Dependencies currently does not recursively resolve child imports when parsing a new PE since it can be really memory-hungry to do so ( it can go over a GB even for “simple” PEs ). This behaviour can be overriden (app-wide) via a property located in “Options->Properties->Tree build behaviour”.

Tree build behaviours available :

ChildOnly (default) : only process PE child imports and nothing beyond.

(default) : only process PE child imports and nothing beyond. RecursiveOnlyOnDirectImports : do not process delayload dlls.

: do not process delayload dlls. Recursive : Full recursive analysis. You better have time and RAM on your hands if you activate this setting.

Limitations

At the moment, Dependencies recreates features and “features” of depends.exe , which means :

Only direct, forwarded and delay load dependencies are supported. Dynamic loading via LoadLibrary are not supported (and probably won’t ever be).

are not supported (and probably won’t ever be). Min-win dlls are not propertly supported. (UPDATED : support of api set schema redirection in 1.5)

dlls are not propertly supported. (UPDATED : support of api set schema redirection in 1.5) There are no checks between Api Imports and Exports for the moment, only dll presence is supported.

No support of esoteric dll load paths (via AppPaths or SxS manifests entries). (UPDATED : minimal support of sxs private manifests search).
