# ncurses.SlackBuild
# Almost entirely the original build script for Slackware Linux by Patrick Volkerding
# Modified by Stuart Winter <mozes@slackware.com> for the Slackware porting Project.
# 1-Mar-2004

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

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

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

# Extract source:
tar xvvf $CWD/$PKGNAM-$VERSION.tar.gz
cd $PKGNAM-$VERSION
