opening a report to track issues with the update of the internal libffi copy to 3.0.9.  will commit this update to the trunk, and later to the py3k branch.

updated on the trunk and the py3k branch

I noticed some failures on Sparc Solaris10 buildbots (both trunk and 3.x)

re-opened to track the issue on Sparc Solaris

no access to solaris hardware. please could you run the libffi testsuite on this machine? make sure that expect is installed.

the ports which are maintained separately still need an update:

libffi_msvc
  libffi trunk now has a port to x86/msvc. might require some
  extra updates from libffi.

libffi_osx:
  3.0.9 has support for darwin on powerpc and x86

libffi_wince:
  same, support seems to be included.

I'll take care of this one.
Would it be a good idea to upgrade to libffi trunk
in Modules/_ctypes/libffi, and get rid of the libffi_msvc
fork completely (by applying an additional small patch)?

I don't have access to such hardware.
I noticed the buildbot failures since libffi was upgraded.

(Adding Ronald for OS X.)

I'm attaching the patch for an update from the trunk; it passes the ctypes tests and the libffi testsuite on i486-linux-gnu.

We should revert the following chunk for configure.ac to generate the Makefile's again, so that we are able to run the testsuite at least with dejagnu:

-AC_CONFIG_FILES(include/Makefile include/ffi.h Makefile testsuite/Makefile man/Makefile libffi.pc)
+AC_CONFIG_FILES(include/ffi.h)

Can you make this change, run autoconf (I have only version 2.64 but 2.65 is needed), and commit please?

done, and updated the patch for the merge from the trunk.

This patch passes the ctypes tests and libffi testsuite on this system:

  Linux tubu64 2.6.24-27-generic #1 SMP Fri Mar 12 00:52:19 UTC 2010 x86_64 GNU/Linux

Please apply.  And thanks for all the help...

See this post, about Solaris failure:
http://bugs.python.org/issue1544339#msg101485

And the proposed patch:
http://sourceware.org/ml/libffi-discuss/2010/msg00016.html

Ignore my last comment. It is not relevant, and the patch is already in 3.0.9.

It seems fixed now.

Reopen the issue: libffi compilation fails on "x86 FreeBSD 3.x" buildbot.

"x86 FreeBSD 3.x" buildbot seems to compile "libffi".
