# gmp.SlackBuild
# by Stuart Winter <mozes@slackware.com> for the Slackware porting Project.
# Heavily based on the original Slackware build script.

# 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

# Determine the CFLAGS for the known architectures:
case $ARCH in
   arm)     SLKCFLAGS="-O2 -march=armv4t"
            LIBDIRSUFFIX="" ;;
   *)       SLKCFLAGS="-O2" ;;
esac

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

# 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).
# 24-feb-2010: Well it seems to work now so it's good.
# but I'll leave this message just incase something breaks in the future.

# 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
