[sword-devel] Mandatory CLucene Dependency

But it seems not to work: Even when commented out, if CLucene is not
installed, dependencies fail.  It has to be there, even if it's not
intended to be used.

And when it is wanted, it seems to be necessary to use e.g.
--with-clucene=/usr, to explicitly specify CLucene's install prefix.
Credit to Terry for pointing this out to Moses and myself in
#gnomesword just a couple days ago.

Not quite true.  In order to build GnomeSword for Cygwin, installing
CLucene is necessary just to get past the configure dependency, even
though until this week I didn't understand why CLucene's availability
was not having any useful effect.  The problems are that [a] Cygwin GTK
has some old crud in a couple #includes and [b] CLucene itself is too
dumb to install its own fundamental .h file in /usr/include/CLucene.
(It mis-installs clucene-config.h in /usr/lib/CLucene.)

Part of my Cygwin GnomeSword build script is:

# fix gtk #includes
cd /usr/include/gtk-2.0/gtk
mv gtkclist.h gtkclist.h.ORIG
sed -e 's/GMemChunk \*/gpointer /' < gtkclist.h.ORIG > gtkclist.h
mv gtkstatusbar.h gtkstatusbar.h.ORIG
sed -e 's/GMemChunk \*/gpointer /' < gtkstatusbar.h.ORIG > gtkstatusbar.h
# ... unpack/build/install CLucene, then ...
cp -pv src/CLucene/clucene-config.h /usr/include/CLucene

This solves the build problems for CLucene under Cygwin.  And then a
GnomeSword search on e.g.
        +god +father +"jesus christ"
is amazingly fast.

Per Terry's instruction earlier this week, I also do this to sword's
configure.ac, to remove the conditionals on CLucene detection,
although it's not clear it's needed in either Linux or Cygwin, now
that I know to use --with-clucene=/usr:

I need to re-tweak my Cygwin build script to account for automatically
handling CLucene detection via --with-clucene=/usr but I haven't
actually done so yet; probably this weekend, after more testing.
