warning in python-value.c

warning in python-value.c

[Joel Sherrill]

Hi,

I'm seeing this in the cross builds of the gdb trunk to any RTEMS target.

For now, I have disabled the python support to continue. 

Any ideas?

What version of Python do you have?  What host are you building on?
And what is the most recent entry in gdb/ChangeLog?

I think I fixed this yesterday:

2009-01-05  Tom Tromey  <tromey@redhat.com>

	* python/python-internal.h (Py_ssize_t): Define as int.

I was seeing this when building on a 64-bit host against Python 2.4.

This is on gcc12 in the CFARM.  So 64-bit debian.
I don't know how to check the python version.  I see
libraries for up to 2.6

Configure command:

 ( ../gdb-cvs/src/configure --target=m32c-rtems4.10 \
   --enable-sim --enable-sim-hardware --enable-timebase \
    --enable-sim-trace && make ) >b.log 2>&1

This is with a native gcc built from the svn trunk if that
matters.

Yours was not there so I updated and retried it.
It now builds so  I guess we just crossed.

Thanks.

Ok, great ... I was using gcc11 :)

For the record, one way to find the python version is to grep for
HAVE_LIBPYTHON in gdb/config.h.  That will tell you what gdb's
configure script picked, which is usually the relevant thing.
