# 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:
zcat $CWD/jpeg-6b.diff.gz | patch -p0 -E || failpatch

# Make package framework:
mkdir -p $PKG/usr/{man/man1,include,bin,lib,doc/$PACKAGE-$VERSION}

# Configure:
./configure || failconfig

# Build:
make -j2 || failmake

# Install into package:
install -m755 cjpeg djpeg jpegtran rdjpgcom wrjpgcom \
              $PKG/usr/bin
install -m644 cjpeg.1 djpeg.1 jpegtran.1 rdjpgcom.1 wrjpgcom.1 \

# Install docs:
cp -favv README *.doc \
         $PKG/usr/doc/$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

# 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
