visual-studio 2017 show - Displaying the #include hierarchy for a C++ file in Visual Studio

4 Answers

The compiler also supports a /showIncludes switch -- it doesn't give you line numbers, but can give a pretty comprehensive view of which includes come from where.

It's under Project Settings -> Configuration Properties -> C/C++ -> Advanced -> Show Includes.

includes graph /showincludes

Problem: I have a large Visual C++ project that I'm trying to migrate to Visual Studio 2010. It's a huge mix of stuff from various sources and of various ages. I'm getting problems because something is including both winsock.h and winsock2.h.

Question: What tools and techniques are there for displaying the #include hierarchy for a Visual Studio C++ source file?

I know about cl /P for getting the preprocessor output, but that doesn't clearly show which file includes which other files (and in this case the /P output is 376,932 lines long 8-)

In a perfect world I'd like a hierarchical display of which files include which other files, along with line numbers so I can jump into the sources:


Not as good as gcc's hierarchical include feature, which shows the direct-line inclusion hierarchy in the case of an error. The "show includes" option in VS shows everything, which is overkill when debugging hierarchical include file problems.

There is now a plugin for Visual Studio called IncludeToolbox. It can list your dependent includes and do more things like a random remove and compile to see if that include was required.
