Dan, Your fix is not the right one. But I recognize that my previous suggestion could lead into error. In fact, tdir_count field is a uint64 in libtiff 4.0. So the correct fix is : uint32 nTemp = (uint32)o->tdir_count; _Tiffmemcpy(n, &nTemp, 4); Even ----------------------------------------------------------------------------------- RE: [Tiff] Re: [gdal-dev] Problem with libTiff on Solaris 10 De : Dan Greve <grevedan@hotmail.com> À : Bob Friesenhahn <bfriesen@simple.dallas.tx.us>, Even Rouault <even.rouault@mines-paris.org> CC : gdal-dev@lists.osgeo.org, tiff@lists.osgeo.org, Andy Cave <andy.cave@hamillroad.com>, mailing list <tiff@lists.maptools.org> Date : Aujourd'hui 16:49:15 Sure enough, the pointer n is not null, and throws a sigsegv fault. Aftern changing from *(uint32*)n=(uint32)o->tdir_count; TO _TIFFmemcpy(n, &o->tdir_count, 4) The execution passes this point, but where as *(uint32*)n should be 1, it is 0. This causes errors later in the GDALOpen call on the tiff dataset, which fails with error "TiffFetchNormalTag:incorrect count for "SamplesPerPixel". debugging continues.... -- Dan Greve -- Software Engineering -- Northrop Grumman Corp.
