# Slackware build script for ntfsprogs-plus (ntfsck)
#
# This packages ONE binary: ntfsck, the NTFS checker from the
# ntfsprogs-plus fork.  The fork's other tools (mkntfs, ntfsresize,
# ntfsclone, ntfslabel, ntfsinfo, ntfscluster) carry exactly the same
# names as the ntfs-3g binaries already on the system, and those must
# keep winning -- so they are deliberately not installed, and neither
# are the fork's libntfs.so.90 or its headers (--disable-shared links
# ntfsck statically against the fork's own libntfs, giving a single
# self-contained binary; ldd shows libc and nothing else).
#
# Upstream's "make install" is not used: it is broken under DESTDIR
# (its install hook mv's libntfs.so* into a $DESTDIR/lib it never
# creates) and it would install the colliding tools above.
#
# No fsck.ntfs symlink is created, on purpose: fsck -A at boot would
# start running this on every NTFS volume, and the dirty-flag,
# boot-sector and chkdsk-scheduling jobs stay with ntfsfix.  ntfsck
# ignores the VolumeDirty flag entirely (neither reports nor clears
# it); run "ntfsck -n" first and repair with -a only when -n found
# something, because -a rewrites the $LogFile restart area even on a
# healthy volume.
#
# Build requirements beyond a stock full install: none (autoconf,
# automake, libtool and libgcrypt ship with Slackware; the tag tarball
# has no ./configure, so autoreconf runs first).
