After you've got Subversion installed, just check it out via:

$ svn checkout http://svn.apache.org/repos/asf/incubator/lucene4c/trunk
lucene4c

That'll drop the working copy in a directory named "lucene4c".

To build it, you'll need to run the "bootstrap" script to run autoconf
and automake, then ./configure --with-apr=/path/to/apr/install

Note that your APR install will need to be a pretty recent Subversion
version of APR, and needs to be built with --enable-experimental-libtool
because currently we only work with APR's jlibtool, not GNU libtool.

You also want to make sure that configure picks up a recent version of
GCJ, preferably GCJ 4. I accomplish this by installing gcc 4 into a
directory and then adding it to the front of my PATH, but I imagine
there are also arguments you could pass to configure to get it to look
for a certain gcj version.

Good luck, and if you have any other questions please feel free to ask.

Hello Garrett:

Thanks for the tips. Am working on getting a build
going.

Q: Why is JCG required? I thought this was a C
implementation?

While the web page hasn't been updated to indicate this yet, we recently
moved from a full C implementation to a C wrapper on top of a GCJ
compiled version of the Java implementation of Lucene. The C
implementation was showing signs of taking way too long to complete, and
using GCJ has allowed us to progress much faster.

Hello Garrett:

Thanks again for the tips so far.

I've gotten gcc-4.0 installed (into
/home/jrobinson/local), and apr, apr-utils, and
apr-iconv installed in /home/jrobinson/local (using
--with-apr=/home/jrobinson/local
--enable-experimental-libtool
--prefix=/home/jrobinson/local),
and I've added /home/jrobinson/local/bin to my PATH,
and /home/jrobinson/local/lib to my LD_LIBRARY_PATH.

On one machine, I get complaints that there's no
javac:
...
javac -classpath ./lib/lucene-1.4.3.jar -d src
src/org/apache/lucene4c/QueryParserHack.java
make[1]: javac: Command not found
make[1]: ***
[src/org/apache/lucene4c/QueryParserHack.class] Error
127
make[1]: Leaving directory
`/home/jrobinson/src/lucene4c-svn/lucene4c'
make: *** [build] Error 2


On another, it doesn't seem to set the TAR location
right, and I get warnings about aclocal.m4:

cd lucene4c && /bin/sh bootstrap && /bin/sh configure
--with-apr=/home/jrobinson/local
--prefix=/home/jrobinson/local && make
Remember to add `AC_PROG_LIBTOOL' to `configure.in'.
You should update your `aclocal.m4' by running
aclocal.
Putting files in AC_CONFIG_AUX_DIR, `config'.

Both machines are running FC1.

More tips are welcome - specifically,
1) where should I get javac from (I don't typically do
java), and
2) how should I resolve the other machine not setting
the tar location right?

Thanks again!

Well, you either need to get some version of javac installed so that we
can build QueryParserHack.class in order to generate it's C++ side
header file with gcjh (yeah, it's a little convoluted), or change the
Makefile.am to do that compilation task with gcj (it's possible to have
gcj compile code to class files, we just haven't gotten around to doing
it yet).

The aclocal.m4 warnings are probably safe to ignore, it's not failing to
find TAR though, it's JAR, it looks for the fastjar binary that GCJ
installs. If you have another version of jar available it's possible to
use that as well.

Ya, we should change those to Fatal errors in the configure script.....

Attached, since 'svn commit' didnt work :)

It looks like Doug just added you to the appropriate authorization file
in svn, so you should be able to commit that yourself now ;-)
