# zlib.SlackBuild
# by Stuart Winter <mozes@slackware.com> for the Slackware porting Project.
# Heavily based on the original Slackware build script by Patrick Volkerding.
# 12-Jun-2004

# Record toolchain & other info for the build log:
slackbuildinfo

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

# Temporary build locations:
export TMPBUILD=$TMP/build-$PKGNAM
export PKG=$TMP/package-$PKGNAM
mkpkgdirs # Delete & re-create temporary directories then cd into $TMPBUILD

# Extract source:
tar xvvf $CWD/$PKGNAM-$VERSION.tar.?z*
cd $PKGNAM-$VERSION || exit 1

# Build static:
./configure \
  --prefix=/usr || failconfig
make clean
make || failmake

# Build shared:
./configure \
  --prefix=/usr \
  --shared || failconfig
make || failmake

# Install headers:
mkdir -p $PKG/usr/include
install -m644 zlib.h zconf.h $PKG/usr/include

# Install shared:
mkdir -p $PKG/usr/lib
cp -a libz.so* $PKG/usr/lib
chmod 755 $PKG/usr/lib/*
install -m644 libz.a $PKG/usr/lib

# Add pkgconfig file:
mkdir -p $PKG/usr/lib${LIBDIRSUFFIX}/pkgconfig
install -vpm644 zlib.pc $PKG/usr/lib${LIBDIRSUFFIX}/pkgconfig/

# Now that libkmod requires libz, we had better move the shared library
# up a level:
mkdir $PKG/lib${LIBDIRSUFFIX}
( cd $PKG/usr/lib${LIBDIRSUFFIX}
  for file in lib*.so.?.* ; do
    mv $file ../../lib${LIBDIRSUFFIX}
    ln -sf ../../lib${LIBDIRSUFFIX}/$file .
  done
  cp -a lib*.so.? ../../lib${LIBDIRSUFFIX}
)

# Install man pages:
mkdir -p $PKG/usr/man/man3
install -m644 zlib.3 $PKG/usr/man/man3

# Install docs:
mkdir -p $PKG/usr/doc/$PKGNAM-$VERSION
cp -favv \
  FAQ INDEX README* \
  $PKG/usr/doc/$PKGNAM-$VERSION
changelogliposuction ChangeLog $PKGNAM $VERSION # Trim down a "ChangeLog" file

# 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
