# gmp.SlackBuild
# by Stuart Winter <stuart@armedslack.org> for the Slackware porting Project.
# Heavily based on the original Slackware build script.
# 14-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/$PACKAGE
export PORTCWD=$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="-O2 -march=armv3" ;;
   powerpc) SLKCFLAGS="-O2" ;;
   sparc)   SLKCFLAGS="-O2" ;;
   *)       SLKCFLAGS="-O2" ;;
esac

# Extract source:
tar jxvvf $CWD/$PACKAGE-$VERSION.tar.bz2
cd $PACKAGE-$VERSION

# Apply patches:
#zcat $PORTCWD/gmp-4.1.2-gcc34-1.patch.gz | patch -p1

# Do NOT specify CFLAGS for ARM otherwise it builds for armv3m
# which won't work on the StrongARM110.
# (Why does it do this I wonder? hmm. Perhaps I'll look at this at some point).

# Build:
make || failmake

# Install into package:
make install DESTDIR=$PKG || failinstall

# Install docs:
mkdir -p $PKG/usr/doc/$PACKAGE-$VERSION
cp -a AUTHORS COPYING COPYING.LIB NEWS README \
      $PKG/usr/doc/$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, 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
