I'm new to C++/Eclipse. I'm trying to get it working to get a new perspective on a problem with a program I wrote in DevCPP. The program is simple and builds fine in DevCPP. In Eclipse, I get hundreds of errors like the one above. I assume the compiler can't see my include files. I've checked that the project settings - GCC C++ compiler - directories contains the location for my include files (D:\MinGW\include\c++\3.4.5). I've prowled around and tried to change 'Discovery Options' to 'GCC C++ Compiler' from 'GCC C Compiler' but it keeps changing back. I guess this is not the problem. Any help would be very welcome. I'm on a tight deadline with many interruptions and this is cracking me up.
