# bc.SlackBuild
# by Stuart Winter <stuart@armedslack.org> for the Slackware porting Project.
# Heavily based on the original Slackware build script.
# 08-Jun-2004

# 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)     SLKCFLAGS="-march=armv3 -mtune=xscale" ;;
   powerpc) SLKCFLAGS="" ;;
   sparc)   SLKCFLAGS="" ;;
   *)       SLKCFLAGS="" ;;
esac

# Untar source:
tar zxvvf $CWD/$PACKAGE-$VERSION.tar.gz
cd $PACKAGE-$VERSION
slackhousekeeping

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

# Apply patches:
zcat $CWD/bc.readline.diff.gz | patch -p1 --verbose --backup --suffix=.orig || failpatch

# Configure:
CFLAGS="$SLKCFLAGS" \
./configure \
   --prefix=/usr \
   --with-readline || failconfig

# Build:
make || failmake

# Install binaries:
install -m755 bc/bc $PKG/usr/bin
install -m755 dc/dc $PKG/usr/bin

# Install man & info pages:
( cd doc
  install -m644 bc.1 dc.1 $PKG/usr/man/man1
  install -m644 dc.info $PKG/usr/info )

# Install docs:
cp -a AUTHORS COPYING ChangeLog Examples INSTALL NEWS README Test \
      $PKG/usr/doc/$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 (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
fi

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