Well... Have you checked your path to your include files ? Could I see the part of the code where the errors occured ?

You just have to compile using gdal_priv.h Then link to gdal_i.lib Then provide with your runtime all the dlls which gdal_fw.dll is depending to. You will find which dlls it is depending to by using Dependency Walker (http://www.dependencywalker.com/). Then your runtime will be able to use all of the image formats drivers that GDAL was compiled to support. I hope this will help.

The linking is done with :gdal_i.libgeos_i.libgeotiff_i.liblibtiff_i.libproj_i.lib But yo may want to use more or less libraries...
