I've got a solution containing multiple projects. I'm only changing the code in one of them, but every time I hit Ctrl+Shift+B, Visual Studio rebuilds all of the others.
I want it to build the other projects, so this is good. What's not good is that, normally, it would see that there was nothing to do. I have a wonky dependency somewhere, so this isn't working.
Is there a tool or macro (or switch) that'll explore the dependency tree and tell me which files are missing or out-of-date, so that I can get it to stop?
I know that I can solve this specific case, by (e.g.) touching all of the project files.
Unfortunately, I've often seen this situation when a file is configured to produce an output file (e.g. an IDL file is configured to output a typelibrary, but doesn't contain a 'library' block, so it'll never create a TLB).
This wouldn't be resolved by touching all of the project files, so I'm looking for something more general to add to my personal toolbox that'll easily tell me why a file is being rebuilt, whether it be because it's older than a dependency, or because the project is misconfigured to expect an output file that will never be produced.
While not directly answering my question: "is there a tool that'll work this out for me?", I found the specific problem by using SysInternals Process Monitor:
The project was configured with /analyze, which requires Visual Studio Team Edition, but the version on this PC is Visual Studio Professional, which doesn't support it. Unfortunately, there appears to be a bug in Visual Studio, where it thinks that the .pchast file should be created, even though it has no way to do so. I've raised this on Connect.
I think I might write a macro for Visual Studio Professional that, if /analyze is turned on, simply creates an empty .pchast file at the end of the build...
