python27 @2.7.2_2 has broken exponentiation

[jeremyhu (Jeremy Huddleston Sequoia)]

I'm having trouble building pypy using MacPorts' python27 (since pypy is not yet installed). It has nothing to do with the selected compiler. This is a python abort before $CC is invoked

Using Apple's /usr/bin/python2.7 instead of MacPorts' ${prefix}/bin/python2.7 gets past this hiccup.

Is this happening right after the build phase starts, before it runs any of the platcheck stuff? If so, I can't reproduce. I'm running a build with pypy deactivated right now.

[jeremyhu (Jeremy Huddleston Sequoia)]

yes, it is happening immediately.

It's probably something odd with my built python27. I'll dig some more...

Let me know if it turns out there's something I need to do in the port.

[jwm.columbia@…]

I'd like to reopen this, since it appears I have the exact same problem. It appears the gcc compiler fails, since it for some reason lacks the Darwin-specific -arch option: -- [platform:execute] /opt/local/bin/gcc-mp-4.5 -c -arch x86_64 -O3 -fomit-frame-pointer -mdynamic-no-pic /var/folders/9q/yg5x8qn176s3gcn095qkkn_00000gn/T/usession-unknown-3/gcctest.c -o /var/folders/9q/yg5x8qn176s3gcn095qkkn_00000gn/T/usession-unknown-3/gcctest.o [platform:Error] cc1: error: unrecognized command line option "-arch" --

The shell command that fails during the build is -- /opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_ports_lang_pypy/pypy/work/pypy-pypy-release-1.6/pypy/translator/goal" && arch -x86_64 /opt/local/bin/python2.7 translate.py --batch --cc=/opt/local/bin/gcc-mp-4.5 --opt=jit --make-jobs=8 --cflags='-m64 -I/opt/local/include -L/opt/local/lib' targetpypystandalone.py --

I am relatively unfamiliar with MacPorts, so I'm unsure of further debugging steps. I'd be happy to supply any further information though.

Apologies for messed up line-breaks, didn't notice that this uses WikiFormatting.

That's not the "exact same problem" ... please open a separate radar for new issues.

[jwm.columbia@…]

Ah apologies, it seems I jumped to conclusions after looking at the main.log, which shows the build failing in the same command.

Replying to jeremyhu@…:

Definitely a bug in the python build. On 10.6 built with Xcode 3.2.6:

>>> 2**64
18446744073709551616L

On 10.7 built with Xcode 4.2:

>>> 2**64
0

[jmroot (Joshua Root)]

Also affects 2.6 but not 3.1 or 3.2.

[ned-deily (Ned Deily)]

If the output above is from cpython 2.7, see #32072

[jmroot (Joshua Root)]

OK, so this is ​http://bugs.python.org/issue11149 and we should just need to add -fwrapv to CFLAGS.
