[osgeo4w-dev] Compile errors using gdal111 and OGRSpatialReference

[Lu, Bo (NRCan/RNCan)]

Hello,

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.

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.

Linker settings:
..\..\..\OSGeo4W64\lib\gdal_i.lib
..\..\..\OSGeo4W64\lib\proj.lib
..\..\..\OSGeo4W64\lib\proj_i.lib

Within main.cpp:

OGRSpatialReference wgs;
wgs.SetWellKnownGeogCS("WGS84");

OGRSpatialReference sfms_epsg;
sfms_epsg.importFromEPSG(42304);

OGRCoordinateTransformation* coordTrans = OGRCreateCoordinateTransformation(&wgs, &sfms_epsg);


Errors:

obj\Debug\main.o||In function `main':|
..\main.cpp|145|undefined reference to `OGRSpatialReference::OGRSpatialReference(char const*)'|
..\main.cpp|146|undefined reference to `OGRSpatialReference::SetWellKnownGeogCS(char const*)'|

..\main.cpp|148|undefined reference to `OGRSpatialReference::~OGRSpatialReference()'|
..\main.cpp|145|undefined reference to `OGRSpatialReference::~OGRSpatialReference()'|

FYI allocating to the heap crashes as well with the same error message i.e., OGRSpatialReference wgs = new OGRSpatialReference();
