# by Stuart Winter <stuart@armedslack.org> 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/$PACKAGE
export PORTCWD=$PWD

# Temporary build locations:
export TMPBUILD=$TMP/build-$PACKAGE
export PKG=$TMP/package-$PACKAGE
mkpkgdirs # Delete & re-create temporary directories then cd into $TMP

# Determine the CFLAGS for the known architectures:
case $PORTARCH in
   arm)     SLKCFLAGS="-O2 -march=armv3 -mtune=xscale"
            SLKLDFLAGS="-lm" ;;
