# Heavily based on the original Slackware build script,

# Paths to skeleton port's source & real Slackware source tree:
export CWD=$SLACKSOURCE/l/db4
export PORTCWD=$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" ;;

  For a ton of additional documentation (too large to include
  here) on writing source code that uses libdb4, please see
  the source tarball db-$VERSION.tar.bz2, which can be found
  in the Slackware source tree in source/l/db4/, or on
  Sleepycat's web site:  http://www.sleepycat.com.
