# Paths to skeleton port's source & real Slackware source tree:

# Temporary build locations:
export TMPBUILD=$TMP/build-$PACKAGE
export PKG=$TMP/package-$PACKAGE
mkpkgdirs # Delete & re-create temporary directories then cd into $TMPBUILD

# Determine the CFLAGS for the known architectures:

# Apply patches:
# Allow xscreensaver to work setgid shadow.  I'd rather avoid requiring
# setuid root on this if at all possible.
zcat $CWD/xscreensaver.setuid.diff.gz | patch -p1 --verbose || failpatch
# Make xsublim (not included in the package but is in the 'hacks' directory)
# use phrases rather than words:
( cd hacks && zcat $PORTCWD/sources/xsublim-phrases.patch.gz | patch --verbose -p0 )

# Configure:

# Build:
# We use '-i' because xscreensaver's NLS support has always been horribly broken
make -i || failmake

# Install into package:
make -i install_prefix=$PKG install-strip

# This is needed for the menus:
mkdir -p $PKG/usr/share/pixmaps
mkdir -p $PKG/etc
mv $PKG/usr/X11R6/lib/X11 $PKG/etc
cp -a $PKG/usr/share/xscreensaver/xscreensaver.xpm $PKG/usr/share/pixmaps/xscreensaver.xpm

# Install docs:
mkdir -p $PKG/usr/doc/$PACKAGE-$VERSION
cp -a README README.debugging \
      $PKG/usr/doc/$PACKAGE-$VERSION

# If necessary, start the fakeroot server so we can set file/dir ownerships:
start_fakeroot

# Apply generic Slackware packaging policies:
cd $PKG
slackstripall   # strip all .a archives and all ELFs
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

# Special policies for this package:
chown root:shadow $PKG/usr/X11R6/bin/xscreensaver
chmod 2751 $PKG/usr/X11R6/bin/xscreensaver

# Build the package:
if [ $PORTARCH = arm ]; then
   slackmp # run makepkg
  else
   makepkg -l y -c n $PKGSTORE/$PKGSERIES/$PACKAGE-$VERSION-$ARCH-$BUILD.tgz
fi

# Perform any final checks on the package:
cd $PKG
slackhlinks     # search for any hard links
