I have a solution in Visual Studio 2008 with multiple projects. I'm using boost in one of them. I've included all the necessary directories and path etc. When I compile the project with that's using boost, it compiles perfectly. When I build the entire solution, it fails and tells me that it can't find a header of boost that I'm using. But it's in the project that compiles. How is this possible?
I've cleaned, rebuilt (the solution and the project) and open and reopened visual studio. Still nothing...
Any ideas?
