New Post: Need help on building the OCX project

You need VC++2010 to be able to compile the ocx, because we use pre-compiled binaries that are made for VC++ 2010.

Here you can read how to build: https://mapwingis.svn.codeplex.com/svn/MapWinGIS/trunk/SupportingLibraries/build/HowToBuild.txt
The key is that you need to download the pre-build binaries and header files (like gdal_priv.h and geos_c.h) from http://www.gisinternals.com/sdk/

Let me know if you have more questions.

Thanks,

Paul
