Hi, > I can't find how to switch on "Jidgo template extraction" at compile time. Jigdo should be enabled automatically at compile time, if zlib is installed. What do you get from ./configure ? If zlib is detected, then it should be: ... checking zlib.h usability... yes checking zlib.h presence... yes checking for zlib.h... yes checking for compressBound in -lz... yes enabled built-in libjte ... Have a nice day :) Thomas
