I have to use Dev-cpp for my Project.My operating system is Windows 8 pro. I downloaded 5.3.0.3 TDM-GCC x64 4.6.1 Setup.It worked,I can compile an easy file(like print Hello World) but I want to use graphics.h function on devcpp.(Borland graphic interface). I did it on Windows 7.But now I got this error sstream: No such file or directory.. Thanks for replying
