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

# Paths to skeleton port's source & real Slackware source tree:
export CWD=$SLACKSOURCE/ap/ash
export PORTCWD=$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
   armv3)   export ARCH_CFLAGS="-O2 -march=armv3 -mtune=xscale" ;;
   powerpc) export ARCH_CFLAGS="-O2" ;;
   sparc)   export ARCH_CFLAGS="-O2" ;;
   alpha)   export ARCH_CFLAGS="-O2" ;;
   x86_64)  export ARCH_CFLAGS="-O2" ;;
   i486)    export ARCH_CFLAGS="-O2" ;;
   mips)    export ARCH_CFLAGS="-O2" ;;
   *)       export ARCH_CFLAGS="-O2" ;;
