py-sip @4.16.1 installs files with wrong target architecture

[dliessi (Davide Liessi)]

I installed MacPorts from source in /opt/macports-i386 following the instructions ​in the guide. I changed the CPU architecture target to build_arch i386 in macports.conf, then I installed py27-sip.

The file sip.so installed by py27-sip appears to have x86_64 as target architecture:

$ file /opt/macports-i386/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/sip.so
/opt/macports-i386/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/sip.so: Mach-O 64-bit x86_64 bundle

Importing sip in Python results in this error:

Forgot to say: I'm running Snow Leopard on a 64 bit capable CPU (Intel Core 2 Duo) with 32 bit kernel.

The SIP build system is probably not honoring environment flags, which is not a big surprise given that it uses Python for all parts of the build. Will you do the following:

sudo port clean py27-sip
sudo port destroot py27-sip
cp `port logfile py27-sip` ~/Desktop/py27-sip_log.txt
bzip2 ~/Desktop/py27-sip_log.txt

then attach the compressed logfile to this ticket. I doubt I'll be able to replicate your issue on my OS (10.8 and 10.9) -- SIP builds as +universal correctly for me as far as I can tell (just checked the actual binary files, and they are indeed "fat"). But, maybe the logfile will help.

Replying to michaelld@…:

Done.

Thanks. I know the issue and have a fix. I'm attaching it as a patch here until I can get it checked in (Trac is not letting me do so right now). Here's how you apply it (I'll assume you've downloaded it to "~/Downloads/py-sip_Portfile.diff")

cd `port dir py-sip`
patch -p0 < ~/Downloads/py-sip_Portfile.diff
sudo port clean py*sip
sudo port -f uninstall `port installed py27-sip | sed -e 1d -e "s@(active)@@"`
sudo port install py27-sip

and, this time the build arch should (will!) be honored. It won't hurt to have SIP installed in this manner; when the update comes through "port selfupdate" should be smart enough to merge them correctly. You can always do:

cd `port dir py-sip`
patch -R -p0 < ~/Downloads/py-sip_Portfile.diff

to revert back to the original Portfile before doing a selfupdate.

I confirm that your patch works for me:
