<p class="MsoNormal">Hello,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Using mingw64 5.2 and the OSGeo4W64 network installation, I can’t seem to compile code using OGRSpatialReference. I don’t know if there is something wrong with my compiler or with the OSGeo4W package and if anyone else is having/had the
same problem.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">It seems the rest of the GDAL API works, it is just OGRSpatialReference in the ogr_spatialref.h that is giving me problems. Interestingly, code using OGRCoordinateTransformation in the same header file compiles properly. <o:p></o:p></p>
