# by Stuart Winter <stuart@armedslack.org> for the Slackware porting Project.
# Heavily based on the original Slackware build script.

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

# Package meta-data:
export PACKAGE=byacc
export PKGSERIES=d
export ARCH=${ARCH:=$PORTARCH}
export VERSION=${VERSION:=1.9}
export BUILD=${BUILD:=1}

# 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
   armv3)   export ARCH_CFLAGS="-O2 -march=armv3 -mtune=xscale" ;;
   powerpc) export ARCH_CFLAGS="-O2" ;;
   sparc)   export ARCH_CFLAGS="-O2" ;;
   alpha)   export ARCH_CFLAGS="-O2" ;;
   *)       export ARCH_CFLAGS="-O2" ;;

# Extract source:
mkdir $PACKAGE-$VERSION
tar xzvf $CWD/${PACKAGE}.${VERSION}.tar.Z -C${PACKAGE}-${VERSION}
cd ${PACKAGE}-${VERSION}

# Ensure sensible permissions in the unarchived source:
slackhousekeeping

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

# Build:
make || failmake

# Install binaries:
install -m755 yacc $PKG/usr/bin
( cd $PKG/usr/bin && ln -sf yacc byacc )

# Install man page:
install -m644 yacc.1 $PKG/usr/man/man1
( cd $PKG/usr/man/man1 && ln -sf yacc.1 byacc.1 )

# Install docs:
cp -a ACKNOWLEDGEMENTS NEW_FEATURES NOTES NO_WARRANTY README \
      $PKG/usr/doc/$PACKAGE-$VERSION

# Enter the package's root:
cd $PKG

# Slackware policies:
slackstripall   # strip all .a archives and all ELFs
slackgzpages -i # compress man & info pages and delete usr/info/dir
slackslack      # set all files to root.root, chmod -R og-w, slackchown, slack644docs
slackdesc       # install slack-desc and doinst.sh

# Build the package:
if [ $PORTARCH = armv3 ]; then
   . $PORTCWD/arm/pkger
 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
