Sure. But why? More specifically, why can I compile PyLucene with
this installation of JCC on this machine, but not my jar file? Same
invocation of "python -m jcc", so far as I can see. But one picks up
the gcj header files, and the other doesn't. Why?
I don't know.
Did you check that you didn't have a stray jni.h lying around ?

OK, I discovered the secret --classpath switch to JCC, and was able to
generate the stubs. However, when I tried to add --build, I run into
the darn Linux gcj problem:

Seems like a bug somewhere in JCC. On the other hand, I was able to
build and install PyLucene with this JCC. Any idea what's going on?
The error is pretty clear about what's going on. You're picking up a =20
gcj header file. For instance, how many jni.h files are there on your =20=
system ?
In particular, is there one being picked up before the JDK's because =20
it's in /usr/include or somesuch ?
Andi..
