Hi,

I am trying to import a spacial reference system into an OGRSpatialReference object using the following function which requires a MapInfo style CoordSys definition string: OGRErr OGRSpatialReference::importFromMICoordSys(const char * pszCoordSys) (websited address: http://www.gdal.org/ogr/classOGRSpatialReference.html#1acf0f6cac3125cc878a99433033c140). This function requires the routine in which it is used to be linked to the MITAB library. The problem is that both the MITAB and GDAL libraries contain OGR and CPL. This creates the following linker errors when I try to compile my routine on Microsoft Visual C++ 2008 Express Edition (VC 9.0), using mitab version 1.7.0 and gdal version 1.6.0.

Is there any way to compile the MITAB and GDAL library in the same C++ routine and avoid these errors?
