bad liblucene4c.la while building lucene4c

I am trying to build lucene4c to use with mod_mbox for
a SoC project. I have checked out the gcj-backend
branch of lucene4c, checked out the trunk version of
apr and built it with the experimental library
enabled, and built lucene4c with gcj4. The resultant
liblucene4c.la file looks like this:

/usr/local/lib

I have never used libtool before but that .la doesn't
look like any others I have seen and mod_mbox doesn't
like it either:

libtool: link: `/usr/local/lib/liblucene4c.la' is not
a valid libtool archive

Anyone have a suggestion?

Try removing liblucene4c.la and just linking directly against
liblucene4c.so? I imagine this is a problem with jlibtool, and enough
peopl ehave mentioned it at this point that I guess we're going to have
to do something about it sooner rather than later...

I really don't mean to be obtuse but as I previously
mentioned I've never used libtool (of any variant). I
suspect I have to hack the generated Makefile to link
against the .so but damned if I can even find the
correct section. A pointer to the Makefile section to
hack would be greatly appreciated.

Who is starting to miss the bad old days when I had to
write the Makefile myself.

Actually, I'm not sure if you'll have to hack the makefile or not...
I'd try just removing the .la file and running make, and seeing if it
does anything useful. If it doesn't, I don't think I can really be much
help to you, since I don't actually have a copy the mod_mbox makefile,
since I don't work on mod_mbox, and I suspect if hand-hacking is needed
that's where it would be.

Another thing to think about is the fact that when building mod_mbox you
might want to try making it use jlibtool, just like Lucene4C does. I
mean Lucene4C manages to get at least one binary (the lcn command line
tool) to link against its library, so jlibtool does apparently manage to
do it in at least some circumstances. If the libtool you're using with
mod_mbox can't seem to do the same thing, it could be that it's GNU
libtool, not jlibtool.
