# Record toolchain & other info for the build log:

# Paths to skeleton port's source & real Slackware source tree:

# Temporary build locations:
export TMPBUILD=$TMP/build-$PKGNAM
export PKG=$TMP/package-$PKGNAM

# Take the relevant bits from the nfs package framework:
tar pxvvf $CWD/_nfs-utils.tar.gz -C$PKG # etc install
# Add startup script:
cat $CWD/rc.nfsd > $PKG/etc/rc.d/rc.nfsd.new
# Off by default, unless there's a previous version that's turned on:
chmod 644 $PKG/etc/rc.d/rc.nfsd.new
# Create the rest of the package framework:
mkdir -p $PKG/usr/doc/$PKGNAM-$VERSION/{nhfsstone,statd}
mkdir -p $PKG/var/log/nfsd

# Set CFLAGS.  If I don't add -D_GNU_SOURCE above then statd fails to build.
# However, after the failed build if I cd into the source dir and make from there
# (outside of this build script) then it adds -D_GNU_SOURCE -DHAVE_TCP_WRAPPER 
# which enables statd to build. I haven't investigated why these flags are not 
# used when building from this script, but adding them in here causes the build
# to complete. 
# This does need some attention.
