如何跟踪用过的DLL（是所谓的DLL hell吗？）

Question

It should be a simple problem, but I do be stumbled on it. The environment is Visual Studio 2008 on Windows 7, the machine also has vs2010, vs2012 installed. (I have to install several VS because various project uses different version)

I have a simple application uses some 3-rd DLLs. 1). When the app is launched from Vs, it is OK.

2). When I copied the DLLs to execute file and launched it from Explorer, the application crashed on C++ library

Something like: Program: xxx.exe File: c:\\program files\\microsoft visual studio 9.0\\vc\\include\\vector Line: 779 Expression: vector subscript out of range

3). I opened a command line and add 'Visual Studio 9.0\\' and 'Visual Studio 9.0\\vc\\bin' before PATH environment variable and launched the app, it also crashed.

I've attached to manual launched/crashed process and compared it with Vs IDE lanuched process for modules and PATH environment, it seems same.... I was frustrated.

Any suggestion? Thanks in advanced.

I found the reason just now. In Visual Studio, there is a 'Debugging | Working Directory' setting, it is project directory by default. Although I copied all DLLs, I missed some configuration file. It's application logic error.

Answer 1

使用SysInternals的进程监视器来跟踪加载了哪个DLL。

Answer 2

I would recommend using Dependency Walker to debug dependency issues.

You can use it in a static mode, or a dynamic mode (from the Profile menu) to diagnose exactly what the loader is doing at runtime. The latter mode sounds like what you are looking for.

'vector subscript out of range' issue seems to be more from your code rather than the DLL dependency issue. However, make sure to reference the correct version of the DLLs - Debug/Release.
