--without-sse will have no effect on a 64-bit build on the part of the code I'm suspecting (it only affects gdal_grid). As all Intel/AMD CPUs supporting 64-bit have SSE and SSE2, SSE2 optimizations are unconditionally enabled. In gcore/rasterio.cpp, can you change line 2869 #if (defined(__x86_64) || defined(_M_X64)) && !(defined(__GNUC__) && __GNUC__ < 4) to #if 0 to remove any SSE2 (and SSSE3) optimization ? -- Spatialys - Geospatial professional services http://www.spatialys.com _______________________________________________ gdal-dev mailing list [email protected] https://lists.osgeo.org/mailman/listinfo/gdal-dev
