Hi All,
I'm new in this mail-list.
I have a problem when trying to use libgeotiff.
I use VC++ 6. After making a project, I add some header files, C/C++ source files and inc files to my project, not all files included in libgeotiff zip file.
They are :
[..] [.] geo_normalize.c tif_ovrcache.c
cpl_minixml.cpp cpl_csv.cpp cpl_string.cpp geotiff.cpp
cpl_string.h tif_ovrcache.h cpl_port.h cpl_minixml.h
tif_config.h tiffvers.h tiffio.h tiffconf.h
tiff.h geo_normalize.h xtiffio.h geokeys.h
cpl_config.h cpl_csv.h geotiff.h geotiffio.h
geovalues.h geo_config.h geo_ctrans.inc geokeys.inc
epsg_units.inc epsg_proj.inc epsg_pm.inc epsg_pcs.inc
epsg_gcs.inc epsg_ellipse.inc epsg_datum.inc epsg_vertcs.inc
Then I include header files in my project and add some code :
TIFF *tif=(TIFF*)0; /* TIFF-level descriptor */
GTIF *gtif=(GTIF*)0; /* GeoKey-level descriptor */
/* Open TIFF descriptor to read GeoTIFF tags */
tif=XTIFFOpen("d:/IMAGERY.TIF","r");
gtif = GTIFNew(tif);
When I build the project, it result in linking error :
readGeoTiffDlg.obj : error LNK2001: unresolved external symbol _GTIFNew
readGeoTiffDlg.obj : error LNK2001: unresolved external symbol _XTIFFOpen
Debug/readGeoTiff.exe : fatal error LNK1120: 2 unresolved externals
I search in some forum, one say that it related to library which can not be found. I look back to my libgeotiff files, there is no lib file there.
Please anyone knows about this?
Thank you
