python25 +universal fails to compile Mac OS 10.4

[wjb@…]

I previously installed MacPorts python2.5 and am trying to switch to +universal variant. Running the command:

sudo port install python25 +universal

installation fails with

--->  Building python25 with target all
Error: Target org.macports.build returned: shell command " cd "/opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_ports_lang_python25/work/Python-2.5.1" && make all " returned error 2

My specs:
MacPorts 1.520
Mac OS 10.4 Intel
Xcode 2.4.1

Any idea on what could be wrong here?

Assigning to maintainer.

The first thing to try is upgrading to the latest MacPorts by running sudo port selfupdate. Then run sudo port clean python25 and try installing again.

I've updated and cleaned python25. The same error occurs when trying to build the universal variant.

I had the same error message building python25 +universal on Mac OS X 10.5.2 with MacPorts 1.6.0. I was able to work around it and build a universal Python by modifying patch-Makefile.pre.in.diff.

The distributed path-Makefile.pre.in.diff calls /usr/bin/libtool with $(LDFLAGS) in its argument list. But /usr/bin/libtool doesn't understand "-arch", or the other options that appeared in $(LDFLAGS) it appears. So I just removed the $(LDFLAGS) part. I don't know if that's the right thing, but it worked for me.

Can you explain more precise what you did? I am a dumb beginner and try to get py25 working on MacOSX 10.5 with macports 1.6.0.

Thanks for helping!

Set up a local ports repository according to the instructions at ​http://guide.macports.org/#development.local-repositories. Then copy the python25 package:

mkdir ~/ports/lang
cp -r /opt/local/var/macports/sources/rsync.macports.org/release/ports/lang/python25 ~/ports/lang/

And apply the patch that I will attach:

cd ~/ports
patch -p1 < ~/python25-universal.diff

Run a portindex:

cd ~/ports
portindex

And edit sources.conf.

Well, we are long past Python 2.5, the recommended Python 2 is now 2.7. I myself don't have 10.4 anymore around, so I can't test it. In Python 2.7 the universal builds are already taken into account in upstream code, so that is better from the start.
