| Just to mention the same issue for Python-2.6.2 and gcc-4.2.0 on aix 5.3 too. |

| AIX doesn't seem listed in the platforms supported by libffi. http://sourceware.org/libffi/ suggests you send platform test results to libffi-discuss@sourceware.org On the other hand, perhaps the libffi version which comes with Python is outdated. |

| Having a look at <http://www- 03.ibm.com/systems/power/software/aix/linux/toolbox/alpha.html> gcc libffi is wel available for Aix, though? That said, I just need python for bzr and associated tools to maintain localy a small number of script, so imho I would be able survive without ffi support in python (even _ctype?). Any idea how to remove this support at build from src time: I have a look at ./configure --help and even try to change some other compilation option like -O2 (in place of default -O3) but nothing seems to be helpfull. Tx for additional advise. |

| Well a few spare time let me investigate this way: using gc[cj] libffi. I so first install libffi-4.2.0-3 as well as libffi-devel-4.2.0-3 (not sure this last one is required, though) then configure python (2.6) with --with-system-ffi but it doesn't seems to be enough to locate libffi so I added symbolic links: /usr/lib/libffi.a -> ../../opt/freeware/lib/libffi.a /usr/include/ffi.h -> \ ../../opt/freeware/lib/gcc/powerpc-ibm-aix5.3.0.0/4.2.0/include/ffi.h /usr/include/ffitarget.h -> \ ../../opt/freeware/lib/gcc/powerpc-ibm-aix5.3.0.0/4.2.0/include/ffitarget.h After that I reach to compile python2.6.2 without error and at a first glance it seems to work fine (just rebuild bzr 1.17 and launch some cmdl, ;<)). Hope this could help for python3 and xlC, r. |

| Python is using the wrong ffi code, it should be using ffi_darwin.c |

| I've just downloaded libffi-3.0.9 (the latest) and it builds with no problems on my AIX 5.3 system. Is there any chance of the version of libffi in Python being updated? |

| According to ffi site (http://sourceware.org/libffi/, the latest version is libffi-3.0.10, dated few days ago (which BTW I've been unable to compile on AIX, while 3.0.9 is OK) So what are those 4.2.0-3 versions coming from? |

| Hello Gilles, The libffi-4.2.0-3 I used, was coming from the previously mentioned repository: <http://www-03.ibm.com/systems/power/software/aix/linux/toolbox/alpha.html>. That said, if I click on link, it points me to <ftp://ftp.gnu.org/gnu/gcc> So, as far as I understand, it's the version of libffi coming with gcc project and so of the same release as the gcc available at this place i.e. 4.2.0-3. What's the difference with sourceware.org/libffi? It's very not clear to me: reading this announce: <http://sourceware.org/ml/libffi-discuss/2009/msg00146.html>, it seems that gcc one is the merge of the upstream? Hth, r. PS: As I was fired from my previous position, I don't have any more access to my testing system and so couldn't more helpful, sorry :<( On 09/21/2011 09:07 AM, Gilles PION wrote: > > Gilles PION<gpion@lfdj.com> added the comment: > > According to ffi site (http://sourceware.org/libffi/, the latest version is libffi-3.0.10, dated few days ago (which BTW I've been unable to compile on AIX, while 3.0.9 is OK) > > So what are those 4.2.0-3 versions coming from? > > ---------- > nosy: +gpion > > _______________________________________ > Python tracker<report@bugs.python.org> > <http://bugs.python.org/issue6006> > _______________________________________ > |

| Although this is closed - it is not (yet) resolved, really. ctypes does not compile on AIX 5.3, or AIX 6.1. Applying the patch posted (https://bugs.python.org/file17098/pyffi.patch) does get rid of most of the problems. However, to completely "fix" it I also copied as follows: cp -rp ../sourceforge/libffi/libffi-3.2.1/src/powerpc ./Python-2.7.8/Modules/_ctypes/libffi/src/powerpc make clean make There are still other issues - BUT - with this ctypes completes as a module of python. |
