per the new release: gifdataset.cpp:178: `struct ExtensionBlock' has no member named `Function' make[2]: *** [gifdataset.o] Error 1 per previous and new release: Also, I have not found the c equiv routines GDALSetMetadata, GDALSetMetadataItem or GDALGetMetadataItem. I was hoping to see them in the newest version ..... Thanks, Diana M. Esch-Mosher
