Well, building pylucene is pretty complicated. Here's a script fragment
I use to build it on OS X. $sitepackages is where to install it, and
$distdir is the prefix of that spot. The Linux script is similarly
complicated by the difficulty of locating a JDK on Linux, and by the
lib/lib64 split. The use of setuptools also means that you have to fool
the nagging condescending sanity checks in setuptools by setting things
like PYTHONPATH.
Hey, it looks like we have a budding configure script in the making here :)
Care to go all the way and contribute it ?
I see you're installing the Lucene jars some place. JCC normally copies them
into the lucene egg it creates...
Still, I think that a setup.py based approach would have the benefit of
telling us where Python is since it would be running already. All the logic
to figure out Java location etc... can also be driven from Python, solving
the other half of the problem. The same approach could be used for figuring
out the Java stuff. Have a small class running in Java tell us.
On Linux, every distro has its own, incompatible, way of telling where java
is. I just experienced this going from Gentoo to Fedora Core 11.
Andi..
