# Build:
make $NUMJOBS || make || failmake

# First, spam the running development system, as ImageMagick is unable to
# properly link the utilities against a new shared library major version
# otherwise which has led to several broken packages over the years:
make $NUMJOBS install || failinstall
rm -f /usr/lib${LIBDIRSUFFIX}/libMagick*.la
/sbin/ldconfig

# Now build again against the new libraries and headers:
make clean
make $NUMJOBS || make || failmake

# Install into package:
make $NUMJOBS install DESTDIR=$PKG || failinstall

# This should certainly not be included.
# It stomps on the libtool package.
rm -f $PKG/usr/lib${LIBDIRSUFFIX}/libltdl.*

# .la files in /usr/lib${LIBDIRSUFFIX}/ should be removed.
# Other .la files should be left alone, as ImageMagick uses them internally
# to locate modules.

# Make sure the proper security policy.xml is installed:
cp -fav config/policy-${POLICY}.xml $PKG/etc/ImageMagick-7/policy.xml

# Provide all the security policy XML files as examples:
for file in config/policy*xml ; do
  cp -fav $file $PKG/etc/ImageMagick-7/$(basename ${file}).example
done

# Nothing but a perl upgrade should replace this (and maybe not even that)
find $PKG -name perllocal.pod | xargs rm -fv

# DESTDIR is still broken about this, but works well enough otherwise:
chmod 644 $PKG/usr/share/man/man3/*
mv $PKG/usr/share/man/man3 $PKG/usr/man
rm -rf $PKG/usr/share/man

( cd $PKG/usr/lib${LIBDIRSUFFIX}/perl5
  # Ditch empty dirs:
  rmdir */* 2> /dev/null
  rmdir * 2> /dev/null )

# Move config files to .new:
( cd $PKG/etc/ImageMagick*
  for file in *.xml ; do
    mv -fv ${file} ${file}.new
  done )

# Copy docs:
#mkdir -p $PKG/usr/doc/ImageMagick-$( echo $VERSION | tr _ - )
mkdir -p $PKG/usr
mv -fv $PKG/usr/share/doc $PKG/usr
cp -fav AUTHORS LICENSE NEWS NOTICE Platforms.txt QuickStart.txt README.txt \

changelogliposuction ChangeLog ImageMagick '*' # because the version is the major one.

# Apply generic Slackware packaging policies:
cd $PKG
slackstripall   # strip all .a archives and all ELFs
slackstriprpaths     # strip rpaths
slack_delete_lafiles # delete usr/lib{,64}/*.la
slackgzpages -i # compress man & info pages and delete usr/info/dir
slackslack      # chown -R root:root, chmod -R og-w, slackchown, slack644docs
slackdesc       # install slack-desc and doinst.sh
slackmp         # run makepkg -l y -c n

# Perform any final checks on the package:
cd $PKG
