python_select does not function on 10.6

[nerdling (Jeremy Lavergne)]

python_select doesn't list the versions of python available from the system and fails to set links when assigning the version.

# python_select -s
none
# python_select -l
Available versions:
current none python25
# sudo python_select python25

there were 4 errors selecting version "python25"!

It seems these are because /opt/local/Library does not exist.

What is your frameworks_dir in macports.conf?

For the system provided python it would require an additional platform darwin 10 block in the Portfile.

Replying to raimue@…:

What is your frameworks_dir in macports.conf?

frameworks_dir /opt/local/Library/Frameworks

Is this all that is needed for the new code block?

platform darwin 10 {
    post-destroot {
        xinstall -m 644 -W ${filespath} python26-apple ${destroot}${prefix}/etc/select/python
    }

    post-activate {
        if {[exec ${prefix}/bin/${name} -s] == "none"} {
            system "${prefix}/bin/${name} python26-apple"
        }
    }
}

frameworks_dir /opt/local/Library/Frameworks

Then python25 should be installed in this path. Please check by port contents python25 if that is the case. Otherwise I cannot understand why files are missing.

Looks good, given that the python26-apple file contains the right paths. As I don't have access to SL myself and cannot verify, please feel free to commit this additional platform yourself.

[nerdling (Jeremy Lavergne)]

python25 only has files in:

• /opt/local/bin
• /opt/local/etc
• /opt/local/include
• /opt/local/lib

In fact, there is no /opt/local/Library.

The path for the python26-apple files follow those of python25-apple:

/usr/bin/python2.6
/usr/bin/pythonw2.6
/usr/bin/python2.6-config
-
/usr/bin/pydoc2.6
/usr/bin/smtpd2.6.py
-
/usr/share/man/man1/python2.6.1.gz
-
-

[nerdling (Jeremy Lavergne)]

Committed the python26-apple and included it in python_select: r53964. I have not yet changed the revision.

Any update on this from anyone?

[dmitrykichenko@…]

Ditto. I am running Leopard off an external drive at the moment but I'd really prefer to be under Snow Leopard full time.

The current version is working fine for me under SL

python25 and python26 have different maintainers and a very different set of patches and Portfiles. Is it possible that python26 maintainers have figured out how to build the python Framework on Snow Leopard and the python25 maintainer hasn't? The python25 port disables the Framework build on darwin 10 (snow leopard).

[blb@…]

Note that 2.5 on 10.6 most likely won't see frameworks, unless someone wants to port the patches to 2.5; see ​the python bug.

[nerdling (Jeremy Lavergne)]

python_select seems to be working just fine for me with python25 and python26.

[mamoll (Mark Moll)]

The contents of ${prefix}/etc/select/python/python25 is (partially) wrong, since there is no Framework. The header files are in /opt/local/include/python2.5 and the library is in /opt/local/lib/python2.5/config/libpython2.5.a

Yes, I don't expect the python25 framework build to get fixed on Snow Leopard. I could add a select file which does not contain the framework paths, but what you are seeing are warnings only.

This is what I get after installing python26 @2.6.2_4+darwin and trying to python_select it:

Selecting version "python26" for python
ln: /opt/local//opt/local/Library/Frameworks/Python.framework/Versions/Current: No such file or directory
ln: /opt/local//opt/local/Library/Frameworks/Python.framework/Headers: No such file or directory

ln: /opt/local//opt/local/Library/Frameworks/Python.framework/Python: No such file or directory
there were 4 errors selecting version "python26"!

[macosforge@…]

A "cd /opt/local && sudo ln -s /opt" got me to the point where I could use python_select against python26. It's a hack, but it'll get you up and going if you're in a bind.

duplicate strings "/opt/local/" in a file '/opt/local/etc/select/python/base', LL9-12. so delete "/opt/local/" strings. Here is a hack.

The problem in this ticket's description is fixed (python25 is a framework build on 10.6 now), as is selecting the system python on 10.6. There is a separate issue covered by #21320.

[cjerdonek@…]

It looks like you guys fixed this, but I am getting this error for python24 after uninstalling/installing python_select today:

sudo python_select python24 Selecting version "python24" for python ln: /opt/local/Library/Frameworks/Python.framework/Versions/Current: No such file or directory ln: /opt/local/Library/Frameworks/Python.framework/Headers: No such file or directory ln: /opt/local/Library/Frameworks/Python.framework/Resources: No such file or directory ln: /opt/local/Library/Frameworks/Python.framework/Python: No such file or directory there were 4 errors selecting version "python24"!

Has the fix not made it into the version of python_select used in "port install", or does the fix not work with python24? Thanks.

Never mind. It seems to be working for me now with python24 after installing and trying with python26. Thanks!
