Description William Bader 2010-02-19 19:35:54 UTC 
On an old RH Linux 9 system, configure detects cups and reports:
checking for cups-config... /usr/bin/cups-config

rpm on this system reports:
gimp-print-cups-4.2.4-5
qtcups-2.0-15
cups-1.1.17-13.3
cups-devel-1.1.17-13.3
qtcups-devel-2.0-15
cups-libs-1.1.17-13.3

Would it be possible for the configure script to test whether ppd.h defines
ppd_attr_t?
My ppd.h has #define PPD_VERSION 4.3 and my cups.h has
cups.h:#  define CUPS_VERSION           1.0117
cups.h:#  define CUPS_VERSION_MAJOR     1
cups.h:#  define CUPS_VERSION_MINOR     1
cups.h:#  define CUPS_VERSION_PATCH     17

This is how the make ends:

CUPS 1.1.17 is too old (over 7 years old) to use the current gdevcups code.
Comment 2 William Bader 2010-02-22 08:29:56 UTC 
I was only hoping that configure would realize that cups was too old and disable
it from the build.  Most of my systems don't have the cups libraries, so
configure automatically disables cups.  One of my older systems has almost every
rpm loaded, and the presence of the old cups libraries broke the build.  It was
easy enough to add --disable-cups to the configure line, but it is one more
special thing to remember, and it would have been nicer if configure would have
given me a warning that the cups libraries were version X and gs requires
version Y or higher.
