OK, I have found the solution for missing cups.h. But why didn't you mention in some readme file, that it must be downloaded from www.cups.org? Now there's another annoying problem (I have downloaded cups-1.1.7-source.tar.gz). Compiling printing/print_cups.c printing/print_cups.c: In function `cups_printername_ok': printing/print_cups.c:174: `__ERROR__XX__NEVER_USE_SNPRINTF___' undeclared (first use in this function) printing/print_cups.c:174: (Each undeclared identifier is reported only once printing/print_cups.c:174: for each function it appears in.) make: *** [printing/print_cups.o] Error 1 Grrrr... -- T.
