Hi Tim,

i got really inspired after seeing your tutorial on this page. I am presently working on development of a custom GIS application using QGIS APIs. I was going through your code and when i tried to complie it in Borland C++ builder i got the error that

undefined structure CORE_EXPORT

I ahve included all the required header files which i came across from QGIS and Qt. Do i need to include any other file for this definition?

Thanks
Kanwar
