# procps.SlackBuild
# by Stuart Winter <mozes@slackware.com> for Slackware ARM
# Heavily based on the original Slackware build script.
# 03-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/$PKGNAM
export PORTCWD=$PWD

# Sometimes this number lags behind:
SOVER=3.2.8
PSMISCVER=22.13

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

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

# Create package framework:
mkdir -p $PKG/{lib,bin,sbin,usr/bin,usr/man/man{1,5,8}} \
         $PKG/usr/doc/{psmisc-$PSMISCVER,$PKGNAM-$VERSION,procinfo-18}
