I decided to try digital mars out instead of Microsofts compiler (visual studio 2013 pro), which is my main dev environment...

I've been looking for an alternative, and while GCC is my favorite outside of windows, I find it not optimum (in terms of filesize, speed wise its great, but not filesize and compile time), and WONT use intels compiler because its biased against other processors and im morally against this...

but I NEED libraries like vector, I'm studying game programming, and while I can make my own versions of SDL or whatnot, I cant build vector from scratch -- I use it for inventories and other such things...

when I try to compile the game Im working on now, for example, it gives me the error:

 ||unable to open input file 'vector.h'|

why is this? GCC, borland, microsoft, and almost every compiler Ive ever used supports this library... I thought it was a basic part of C++, as well as part of the language standard? am I missing some files, or is DM C++ just not including it?

I wanted to add, I didnt actually put vector.h in at first...

it ALSO says the same thing as just <vector> without the extension -- and in the dm/include folder there is no vector either... at all..
