[Pyobjc-dev] pyobjc 2.3 install fails

[Mark S. <sie...@st...>]

Hi,

I downloaded pyobjc 2.3 fro http://pypi.python.org/pypi/pyobjc

When I do "setup.py install", it apparently downloads a bunch of other stuff, ending with:

...

error: Could not find required distribution pyobjc-core

As far as I can tell, some part of it must be missing from pypi.  Any ideas?

That's odd, pyobjc-core is on pypi and should work just fine.

Could you try "easy_install pyobjc-core==2.3" followed running "python setup.py install" for pyobjc itself again?

I did this:

setenv PYTHONPATH     /Users/sienkiew/py/lib/python2.7/site-packages
easy_install --prefix ~/py pyobjc-core==2.3

It installed something that involved compiling a lot of C code.  During the install, there were a few things that look broken, though:


libtool: link: ar cru .libs/libxml2.a  SAX.o entities.o encoding.o error.o parserInternals.o parser.o tree.o hash.o list.o xmlIO.o xmlmemory o uri.o valid.o xlink.o HTMLparser.o HTMLtree.o debugXML.o xpath.o xpointer.o xinclude.o nanohttp.o nanoftp.o DOCBparser.o catalog.o globals o threads.o c14n.o xmlstring.o xmlregexp.o xmlschemas.o xmlschemastypes.o xmlunicode.o xmlreader.o relaxng.o dict.o SAX2.o xmlwriter.o legac .o chvalid.o pattern.o xmlsave.o xmlmodule.o schematron.o

ranlib: file: .libs/libxml2.a(HTMLparser.o) has no symbols
ranlib: file: .libs/libxml2.a(HTMLtree.o) has no symbols
... repeats for about 20 more files ...

Later, it finds the same problem again:

libtool: install: ranlib /private/var/folders/1w/1wzkS8Y4H44BBu-c3gTR7k++2Ws/-Tmp-/easy_install-7MaF7K/pyobjc-core-2.3/build/libxml/lib/libx l2.a

...


And later:

Modules/objc/test/properties.m:24: warning: Mac OS X version 10.5 or later is needed for use of property
Modules/objc/test/properties.m:25: warning: Mac OS X version 10.5 or later is needed for use of property

Modules/objc/test/properties.m:27: warning: 'assign' attribute (default) not appropriate for non-gc object property 'prop4'


It is 10.5.  system_profiler says "System Version: Mac OS X 10.5.8 (9L31a) )"

And finally:

The easy_install step did not produce a working pyobjc:

>>> import pyobjc

So I continued with the setup.py install step:

 python setup.py install --prefix ~/py

It also skipped a lot of files:

That also did not produce a working system, but I have a lot more on pythonpath:

At this point, I'm thinking there must be something odd about my system that two different versions do not work at all, even when installed with easy_install.  Unfortunately, I don't really know enough about easy_install to know what questions to ask next.  Do you have any suggestions?

This is harmless, due to the way pyobjc compiles a 3th party library we end up with some empty C object files.

This is not a problem for using pyobjc, the warnings are for parts of the unittests for pyobjc-core.

That's expected. Use 'import objc' instead.

You seem the end up with a complete installation. Does 'import Foundation' or 'import AppKit' work?

Thanks for the clarification on those un-important errors.

Oh - sorry.  (I'm not the user of this package; I just install things.)

I get this now from pyobjc 2.3:

>>> import objc
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/Users/sienkiew/py/lib/python2.7/site-packages/pyobjc_core-2.3-py2.7-macosx-10.4-i386.egg/objc/__init__.py", line 24, in <module>

Foundation and AppKit both start to import, but they get this same exception when they try to import objc.

With pyobjc 2.2 it is a different symbol:

>>> import objc

Normally, I would go hunting for the references to the missing symbols and I would look for where they came from, but as far as I can tell, easy_install does not leave any source code behind.  Is there a normal source distribution I can download, so I can see what the code does?

( Actually, that hints at my next question:  Is it possible to install pyobjc from a local copy of the software -- e.g. while not connected to the internet?  Eventually, I have to take this to systems with more strict configuration control. )

No need to apologize.

That's one error I hadn't expected.  Which python do you use?   Are you using a prebuilt binary from the python.org website or something else? 

What's the output of this code:

:>>> import sysconfig
:>>> print sysconfig.get_config_var('USE_TOOLBOX_OBJECT_GLUE')

I'd expect that this prints None on your system, which is a configuration I haven't tested in a long while.

There are source archives for all bits of pyobjc on PyPI.  I don't have an archive with all of PyObjC at this time.

The setup.py file for 'pyobjc' itself contains a list of subprojects, if you install the source archives for the subprojects in the order they are listed there you should be able to install without an internet connection.

It is Python 2.7.1 compiled from source as an i386 executable (32 bits) on Leopard.

It says 0, not None.

In the python build procedure that we use here, I see that my configure line includes --disable-toolbox-glue --disable-framework --disable-universalsdk.  At one point, all three of them were necessary to get a python that worked, but that choice of options is many years old and I'm not sure I ever knew why those are the options to use.  I think it is partly because we don't want this python to try to go into /Library or whatever.

I'll take a look - thanks!

I think it is partly because we don't want this python to try to go into /Library or whatever.

This is the problem.  If I recompile python without --disable-toolbox-glue these things work:

- I can install pyobjc 2.2 with
	easy_install pyobjc==2.2

- I can install pyobjc 2.3 with
	easy_install --prefix ~/py pyobjc-core==2.3
	easy_install --prefix ~/py pyobjc==2.3

I've come over to the belief that there are so many environment variation that it makes sense to explicitly check for prerequisites in the setup.py.  For example, when I have C extensions, I call a function that confirms that Python.h is really present in the directory that Python says it is in.  (Many linux distributions decide to make it part of a "development" package, so even though distutils will tell you where it is, the file isn't actually there.)

I can suggest something like:

if not sysconfig.get_config_var('USE_TOOLBOX_OBJECT_GLUE') :
	print "pyobjc requires a python interpreter that was compiled with --enable-toolbox-glue"
	sys.exit(1)  # exit 1 so the build is recognized as failing


Thanks for all the help!  I never would have had a solution otherwise.
