libzzip build fails because python is not found

[fherwig@…]

I have put a new installation of macport and get this error

[Users/fherwig] > install libzzip

Seems to indicate I don't have python, but I do, just installed it new from Enthought.

[ryandesign (Ryan Carsten Schmidt)]

MacPorts will not use your Enthought Python, or any other external libraries or programs you may have installed Read the FAQ for why.

libzzip builds fine for me, even with the Python included with Mac OS X; I wonder why yours did not find that.... Perhaps you could attach the config.log?

session log python path libzzip port fails to install

[fherwig@…]

I added a session log after cleaning up things. Seems I have everything in place, macport python is there and working, but libzzip does not want to install.

[ryandesign (Ryan Carsten Schmidt)]

libzzip just needs any "python" -- that is to say, either /usr/bin/python (which comes with Mac OS X) or /opt/local/bin/python (which is created when you run python_select, which is provided by the python_select port). Do either of these work? What do they say?

/usr/bin/python --version
/opt/local/bin/python --version

I tried python 2.6:

vortex$ python_select -s
python26

vortex$ /opt/local/bin/python --version 
Python 2.6.6

vortex$ sudo port install libzzip

Replying to fherwig@…:

vortex$ /usr/bin/python --version
Python 2.7.1 -- EPD 7.0-2 (32-bit)

So that is this Enthought Python you mentioned? It has overwritten the Python that Apple provided with Mac OS X! That is very bad and we probably cannot help you in this case. You should reinstall the Python that came with Mac OS X. I'm not sure how to do that, short of reinstalling all of Mac OS X.

[fherwig@…]

No worries, the original Apple python 2.5 is still there, I had just replaced the link because I like the EPD for science applications. For the purpose of these installation tests I have put all back in place:

vortex$ /usr/bin/python --version 
Python 2.5.1

vortex$ ls -lat /usr/bin/python
lrwxr-xr-x  1 root  wheel  67 26 Mar 23:00 /usr/bin/python -> /System/Library/Frameworks/Python.framework/Versions/2.5/bin/python

vortex$ python_select -s
python25-apple

vortex$ sudo port install libzzip

vortex$ 

But still not libzzip. As you can see above I have also tried using a macport python2.6 via python_select. To no avail.

[jmroot (Joshua Root)]

Looks like you didn't clean between changing the link and retrying the build.

[fherwig@…]

I am not sure what you mean by 'clean'. I selected the 2.6 python using python_select, the restarted just in case and then checked the python:

w122-146$ pytnon
-bash: pytnon: command not found
w122-146$ python
Python 2.6.6 (r266:84292, Mar 26 2011, 20:58:46) 
[GCC 4.0.1 (Apple Inc. build 5493)] on darwin
Type "help", "copyright", "credits" or "license" for more information.

Then tried installing libzzip:

Users/fherwig] > install libzzip

--->  Building libzzip
Error: Target org.macports.build returned: shell command failed (see log for details)
Log for libzzip is at: /opt/local/var/macports/logs/_opt_local_var_macports_sources_rsync.macports.org_release_ports_archivers_libzzip/main.log

And still it complains 'python not found'.

[ryandesign (Ryan Carsten Schmidt)]

Replying to fherwig@…:

I am not sure what you mean by 'clean'.

I mean: run:

sudo port clean libzzip

This deletes the previous failed build attempt. Then you can try installing again from the beginning.

[fherwig@…]

Thanks for the help, this works! Wonderfull!

[ryandesign (Ryan Carsten Schmidt)]

Ok, so the problems were because you had replaced Mac OS X's python with a link to some other python, and restoring things to a factory configuration made it work. So there's nothing we need to change in MacPorts.
