jython build

[Tom Tromey]

I just checked in a big change to the jython Makefile.am.  I fixed
srcdir!=buildir issues.  I also fixed some other build bugs.  Finally,
I fixed the jython crash problem -- the problem was that jython.java
was getting compiled into the executable twice.

Cool.  Why doesn't this show up as a link problem?

One copy was in the executable and another copy was in the shared
library.  At link time this is allowed.  That's inconvenient for us...

jython still doesn't work, at least the test Alex told me fails:

    creche.  CLASSPATH=/x1/rhug/build/jython/jython.jar:/x1/egcs/install/share/libgcj.jar:. ./test_jython /x1/rhug/rhug/jython/tests/test-all/testall.py

      File "/home/apbianco/src/rhug/jython/upstream/src/Lib/test/test_support.py", line 43, in ?
    ImportError: no module named javaos

I haven't started looking at this yet.

Thanks. I should have thought of the -d option.

Ha. That's what I didn't catch. One C-_ too many and my binary would
fail, right after a libgcj upgrade. I thought libgcj was broken.

Me too.  It took me a surprisingly long time to suspect this.
A link-time error would be nice.

I found out that you have to put a copy of <rhug-src>/jython/upstream/src/Lib
where your jython.jar file resides -- I got confirmation of this by
installing the jar file and Lib/ into a new location and things ran
OK. Which means that we will have to take that into account for the
install target. We could probably put it in share/, but maybe renaming
it jython-lib (I think there's a way to change it in
org/python/core/PySystemState.java.)

I was trying to work on the install target, by `make install' tells me
the following:

  /bin/sh ../libtool --mode=install /usr/unsupported/bin/install -c  lib-org-jython.la /home/apbianco/install/rhug/install-x86//lib/lib-org-jython.la
  libtool: install: warning: relinking `lib-org-jython.la'
  cd /home/apbianco/build/rhug/i686-pc-linux-gnu/jython; /bin/sh ../libtool --mode=relink gcj --encoding=8859_1 -fassume-compiled -fCLASSPATH=/home/apbianco/src/rhug/jython/upstream/src:/home/apbianco/src/rhug/jython/../gnu.readline/...
  ...

  mv: cannot stat `lib-org-jython.so.0.0.0': No such file or directory

Do you know why I get this error?

Afraid not.

Somehow my --prefix ended up empty so now I'm rebuilding from scratch
to see if I can reproduce the problem.  This should take a while.

It looks like it was a glitch. I removed lib-org-jython.la and the
error went away.
