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

# Kernel version:
KVERSION=${KVERSION:-2.4.32}

# 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:
case $PORTARCH in

   powerpc) export SLKCFLAGS="-O2" ;;

# Extract source:
tar jxvvf $CWD/$PACKAGE-$VERSION.tar.bz2

CFLAGS="$SLKCFLAGS" \
./configure \

# Install into package dir:

# 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 (root:bin), slack644docs
slackdesc       # install slack-desc and doinst.sh

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

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