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

# Temporary build locations:
export TMPBUILD=$TMP/build-$PKGNAM
export PKG=$TMP/package-$PKGNAM
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.

# Add support for the electricsheep distributed screensaver:

# 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 )

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

# Install docs:
mkdir -p $PKG/usr/doc/$PKGNAM-$VERSION
cp -a README* \
      $PKG/usr/doc/$PKGNAM-$VERSION

# Insert an older version of xscreensaver-getimage-file to avoid depending
# on libwww-perl.  Maybe we'll eventually add this, but bundling 14 perl
# modules is a lot of maintainance just to get slidescreen working again.
# This restores the functionality that we had before without all that.

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

# 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/bin/xscreensaver
chmod 2751 $PKG/usr/bin/xscreensaver

slackmp         # run makepkg -l y -c n

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