That library is binary incompatible with what XEmacs expects. You're looking at the wrong file. Look at tiffio.h. The version XEmacs can use looks like: /* * This define can be used in code that requires * compilation-related definitions specific to a * version or versions of the library. Runtime * version checking should be done based on the * string returned by TIFFGetVersion. */ #define TIFFLIB_VERSION 19960307 /* March 7, 1996 */ The newer version Hrvoje has is: /* * This define can be used in code that requires * compilation-related definitions specific to a * version or versions of the library. Runtime * version checking should be done based on the * string returned by TIFFGetVersion. */ #define TIFFLIB_VERSION 19970127 /* January 27, 1997 */
