OpenIndy-Core is the kernel of OpenIndy. It contains all classes that represent the structure behind OpenIndy. OpenIndy-Core is included as a shared library into OpenIndy as well as all plugins developed for OpenIndy.
OpenIndy-Core is developed with the Qt framework (Qt libs + Qt Creator IDE). You can download the framework here.
The easiest way to build OpenIndy-Core is to use the Qt Creator. You can build OpenIndy-Core in debug or release mode.
First you need to compile the OpenIndy-Math library.
Afterwards you can compile OpenIndy-Core using the same compiler as for the OpenIndy-Math project.
