Many people in C + + development have chosen vs as the development platform, but it is also possible to develop C + + with Eclipse. Here's how to use the CDT of Eclipse to build a standard C/D + + development environment.

1. Brief Introduction:

We know that the program consists of the source code to the last generation of the running program requires the following steps: Edit-and-compile connection. Eclipse is the editor, in order to be able to compile the C + + source code We also need a compiler, here we choose MinGW.

There is no introduction to eclipse, just a brief introduction to CDT and MinGW.

The CDT full-C + + development Toolkit is an open source project implemented entirely in Java. For us starters, it can be thought of as a plug-in used in eclipse, which can be used to develop C + + projects.

MinGW full name minimalist GNU on Windows, for us beginners only need to know that it is a compiler, you can compile C + + source code.
