# Record toolchain & other info for the build log:

# Paths to skeleton port's source & real Slackware source tree:
export CWD=$SLACKSOURCE/$PKGSERIES/$PACKAGE
export PORTCWD=$PWD

# 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
   arm)     export ARCH_CFLAGS="-march=armv3 -mtune=xscale" ;;
   powerpc) export ARCH_CFLAGS="" ;;
   sparc)   export ARCH_CFLAGS="" ;;

# Install:
mkdir -p $PKG/usr/{lib,include}
install -m644 libmpeg.a $PKG/usr/lib

# Install docs:
mkdir -p $PKG/usr/doc/libmpeg-$VERSION
cp -a CHANGES README test.mpg doc \
      $PKG/usr/doc/libmpeg-$VERSION

# Slackware 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
   . $PORTCWD/arm/pkger
 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
