Unable to install numexpr-1.3.1 on Mac OSX v 10.6.4

[GoogleCodeExporter]

What steps will reproduce the problem?

$ python setup.py install (from numpexpr directory)

What is the expected output? What do you see instead?

Please provide any additional information below.

I am really looking forward to using numexpr to support PyTables, but until I 
can get the install to work, I'm dead in the water.  I am not expert at doing 
installs, so probably doing something dumb.  Help greatly appreciated.

Here is an update of my efforts.

I installed the optional XTools package to get the GCC compiler, which seems to 
have fixed the "gcc-4.0: command not found" error.  I ran "python setup.py 
build" again and encountered a new error message given below.  Afraid I'm 
getting out of my depth here.

Update # 3:

I looked around for a stdarg.h file on my hard drive and found some, and copied 
the most recent (about a year old) into 
Developer/SDKs/MacOSX10.4u.sdk/usr/include/.  I was then able to run python 
setup.py build, followed by python setup.py install, without error.

Unfortunately, when running the recommended test ("import numexpr; 
numexpr.test()") I got the following error.  

Markm-Mac:numexpr-1.3.1 markhmoulton$ python -c "import numexpr; numexpr.test()"
Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "numexpr/__init__.py", line 14, in <module>
    from __config__ import show as show_config, get_info
ImportError: No module named __config__

The __config__ module does exist --  
/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/nu
mexpr-1.3.1-py2.6-macosx-10.3-fat.egg/numexpr/__config__.py.  And I would 
expect Python to find it on its search path.  I haven't figured out yet why it 
does not. 

So I guess my question has reduced to "How can I get the __init__ file in 
/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/nu
mexpr-1.3.1-py2.6-macosx-10.3-fat.egg/numexpr/ to recognize the __config__ 
module sitting next to it?"

That's strange.  Where are you running the tests from?

Can you delete all the directory 
/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/nu
mexpr-1.3.1-py2.6-macosx-10.3-fat.egg, re-compile, and re-install again?  
Please run the test suite from *outside* numexpr sources dir, just in case.

Luck!

I really appreciate your getting back to me.  

Looks like the problem is solved.  I didn't delete and re-install.  I just 
changed where I was running the test file from.  The Python docs seemed to say 
that setup.py should be run from inside the unzipped package folder, which I 
had put in the Applications directory in my Mac.  That's where I ran build, 
install, and the "import numexpr; numexpr.test()" commands.  When I instead ran 
it from my usual working python scripts directory, the test ran fine and I am 
now able to import numexpr.  I assume that running the test module from the 
Applications directory is tantamount to running it from inside the package, 
which I gather is not allowed in Python 2.7 and up, though I am pretty confused 
by Python relative/absolute import behavior in packages and probably have it 
wrong.

So to sum up, my Mac install ran into three glitches:  a) a missing gcc 
compiler, which required installing XTools; b) a missing stdarg.h file, which 
required copying another into the requisite folder; c) running from inside the 
Applications directory instead of outside.  I have no idea whether other Mac 
users would encounter similar issues but thought you might like to know.  
Anyway, it runs and I'm in heaven.

Thanks again for responding and for your important software.

Here is the printout before and after I ran from my Py_Scr directory.  (I added 
the "Yes, this is the test module" comment to the tests/test_numexpr.py module 
as a confirmation.)

Yes, this is the test module.

Yeah, there are always quirks derived from running the test suite right 
straight at the installation directory.  To be frank I don't know why is this, 
but at least your experience could help other users visiting this.

Closing the ticket.
