# Special version needed for Ghostscript release candidates (e.g. "Version: 9.14pre15rc1" for 9.15rc1).
# Version 9.15rc1 would be newer than 9.15 (run "zypper vcmp 9.15rc1 9.15") because the rpmvercmp algorithm
# would treat 9.15rc1 as 9.15.rc.1 (alphabetic and numeric sections get separated into different elements)
# and 9.15.rc.1 is newer than 9.15 (it has one more element in the list while previous elements are equal)
# so that we use an alphabetic prefix 'pre' to make it older than 9.15 (numbers are considered newer than letters).
# But only with the alphabetic prefix "9.pre15rc1" would be older than the previous version number "9.14"
# because rpmvercmp would treat 9.pre15rc1 as 9.pre.15.rc1 and letters are older than numbers
# so that we keep additionally the previous version number to upgrade from the previous version:

%description
Crippled Minimal Ghostscript which is not meant
to be used by end-users.

Minimal Ghostscript provides only the file format drivers
in particular to output JPEG PNG PostScript and PDF files
but no printer drivers (in particular neither 'cups'
nor 'ijs') and no X11 drivers.

The ghostscript-mini package is only meant to be used
by the openSUSE build service to avoid possible loops
in the build dependencies because ghostscript-mini
has minimal build dependencies (in particular
neither CUPS nor X11 build dependencies).

For most packages which need to only run
Ghostscript during build, a single line
"BuildRequires: ghostscript-mini"
should be sufficient in the RPM spec file.

For most packages which need Ghostscript
development files to build, a single line
"BuildRequires: ghostscript-mini-devel"
should be sufficient in the RPM spec file.

The ghostscript-mini package in the openSUSE build
service contains no sources and it must not contain
any source files. The ghostscript-mini package is only
a link to its matching ghostscript "parent" package.
Only that ghostscript package must contain all sources
and any changes must happen only for that ghostscript
package. This means any changes for the ghostscript-mini
package will be rejected in the openSUSE build service.

# Patch100 remove-zlib-h-dependency.patch removes dependency on zlib/zlib.h
# in makefiles as we do not use the zlib sources from the Ghostscript upstream tarball:
#patch100 -p1 -b remove-zlib-h-dependency.orig
%patch101 -p1
# Do not use the freetype jpeg libpng tiff zlib sources from the Ghostscript upstream tarball
# because we prefer to use for long-established standard libraries the ones from SUSE
# in particular to automatically get SUSE security updates for standard libraries.
# In contrast we use e.g. lcms2 from the Ghostscript upstream tarball because this one
# is specially modified to work with Ghostscript so that we cannot use lcms2 from SUSE:
#rm -rf freetype jpeg libpng tiff zlib
rm -rf freetype jpeg libpng tiff

# --disable-dbus to have nothing related to D-Bus in the minimal Ghostscript.
# --without-ijs to disable IJS printer driver support in the minimal Ghostscript.
# --with-drivers=FILES to have only the file format drivers
#   but no printer drivers in the minimal Ghostscript.
# --without-x to not use the X Window System.
# --without-omni to disable the outdated and unmaintained omni driver.
# --enable-openjpeg because since Ghostscript 9.05 JasPer is deprecated
#   (--without-jasper is now an unrecognized option by configure)
#   and Ghostscript now ships modified OpenJPEG sources for JPEG2000 decoding
#   (replacing JasPer - although JasPer is still included for this release)
#   Performance, reliability and memory use whilst decoding JPX streams are all improved.
#   see also http://bugs.ghostscript.com/show_bug.cgi?id=691430
# --without-ufst and --without-luratech because those are relevant to commercial releases only
#   which would require a commercial license.
# --without-libpaper disables libpaper support because SUSE does not have libpaper.
