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

# Configure:
export CFLAGS="$SLKCFLAGS"
./configure \
  --prefix=/usr \
  --mandir=/usr/man \
  --libdir=/usr/lib${LIBDIRSUFFIX} || failconfig

# Build:
make $NUMJOBS || failmake

# Install:
make install DESTDIR=$PKG

# Install docs:
cp -favv README \
         $PKG/usr/doc/$PKGNAM-$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
slackmp         # run makepkg -l y -c n

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