[Qgis-developer] How do you build the sample QGis application?

[Marco Hugentobler]

Hi Henri

Hm, the link https://svn.osgeo.org/qgis/trunk/code_examples/ works for me.

Yes, you may use qmake. Just link your application with libqgis_core.dll and 
maybe with libqgis_gui.dll

>CORE_EXPORT= GUI_EXPORT= 
is for Linux where you don't need any dllexport macros

>CORE_EXPORT

> GUI_EXPORT

Yes, on windows with msvc, you need to define those export macros.

Regards,
Marco
