# perl.SlackBuild
# by Stuart Winter <stuart@armedslack.org> for the Slackware porting Project.
# Heavily based on the original Slackware build script by
# Patrick Volkerding & David Cantrell.
# 01-Jun-2004

# 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

# Additional required modules:
XMLPARSER=2.34
DBI=1.52
DBDMYSQL=3.0006

# : IMPORTANT VERSION INFORMATION :
# IMPORTANT: also update -Dinc_version_list in ./configure below!

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

# Determine the CFLAGS for the known architectures:
case $PORTARCH in
#   arm)     export SLKCFLAGS="-Os -march=armv3 -mtune=xscale" ;;
   arm)     export SLKCFLAGS="-O2 -march=armv3 -mtune=xscale" ;;
   powerpc) export SLKCFLAGS="" ;;
   sparc)   export SLKCFLAGS="" ;;
   *)       export SLKCFLAGS="" ;;

# Perform any final checks on the package:
