I'm using Visual Studio 2010 and am trying to
#include <string>
in a C++ configured project. However, I get over 100 errors when I try to do so, as shown at the bottom of this post. I also tried including algorithm, iostream, and map to see if I got the same results (and I did), which leads me to believe it may have something to do with the STL or including anything other than .h files. I noticed that there are already STL files within the
C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\include\
directory. By trying to use strings, am I somehow interfering with some kind of preset VS STL? Or is this some other issue?
I also tried getting the source code for the STL and putting it in a folder in the same directory as my .cpp file to reference it there but then I ran into a host of problems with the includes within the STL files. Any ideas?
