Dependencies - 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

• v1.7 :
  • 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

NB : due to limitations on /clr compilation, Dependencies needs Visual C++ Redistributable installed to run properly.

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.

Since v1.6, Dependencies is also packaged as an appx package (the Windows equivalent of a .deb file) which can be installed locally. However, you also need to add the test certificate DependenciesAppx_TemporaryKey.cer to your cert hive.

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 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.
• RecursiveOnlyOnDirectImports : 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).
• Support of api set schema redirection since 1.5
• Checks between Api Imports and Exports.
• Minimal support of sxs private manifests search only.

  • phlib, which does the heavy lifting for processing PE informations.
  • peview, a powerful and lightweight PE informations viewer.
