2012.11.29 10:10 "Re: [Tiff] Error in TIFFWriteDirectory when writting multi page TIFF", by Jorge Martin

Hello Dave,

You were right!! I have re-compile my gdal library using the external libtiff and it runs correctly.

However, I had some problems trying to compile gdal-1.8.1 against an external libtiff and libgeotiff. There is a problem with libtool when gdal is generating libgdal.lai because gdal set a wrong path to the external libtiff. To avoid the problem, it is necessary to use system libtool.

Thank you very much!!!

Best Regards,

Jorge

I have discovered that the problem is only appearing in a code that is linked to libtiff and also to libgdal. In the other cases the executable is not linked to gdal library.

I have removed gdal library in the code that reproduces the problem and it disappears, the multi-file is written correctly.

I think that it could also disappears if I change the order of linking libtiff and libgdal libraries in the makefile.

I am trying to write multi-file TIFF. In some cases I am obtaining the following error from TIFFWriteDirectory function:

TIFFLinkDirectory: Error fetching directory count.

     TIFFReadDirectory help says:

      "*Error fetching directory count*. A read error occurred when
fetching the directory count field for a previous directory. This can occur
when setting up a link to the directory that is being written."

But I do not understand the origin of the error and how to solve this problem, because it only writes the first image.

Does anyone know how to solve this error?
