Hi! I'm having difficulties in using JNA on IBM (x series) ppc64 architecture with Linux SUSE SLES 9. It was suggested that maybe the problem was in the libffi used.

Does JNA use closures?  There's an outstanding PPC64 patch here:
http://sourceware.org/ml/libffi-discuss/2008/msg00112.html

Could you please try with this patch applied?

Jakub - I think you were the last to do work on the PPC64 port. Could you please look at this patch?

Thanks,

I tried to run libffi testsuite as follows:
-starting in the lidffi directory inside jna/native
mkdir build; cd build; ../configure; make; make check

Some tests failed and so I wanted to know how I could resolve my problem and (hopefully) make JNA work.
I also tried to install libffi (version 3.0.8) as a standalone, but the testsuite failed even in that case.

This is the result of the tests for the jna/native/libffi:

Native configuration is powerpc64-unknown-linux-gnu

=== libffi Summary ===

# of expected passes 1519 # of unexpected failures 34 # of unexpected successes 5 # of expected failures 5 # of unsupported tests 15

Can someone tell me what could be the problem and what steps should I take to resolve it?

Thanks,
Daniela Quaresima.
