Installing C SDK for couchbase, Mac OSX 10.6.8 -- How can I correct cmake errors? - cmake

Question

I am trying to get couchbase up and running for python on Mac OSX 10.6.8. I'm following the instructions here:
http://docs.couchbase.com/couchbase-sdk-python-1.2/index.html#getting-started
But I'm stuck on step 2:
Download and install the C library.
According to the instructions for installing the C SDK here:
http://docs.couchbase.com/developer/c-2.4/download-install.html
I did this:
~$ brew update
....
....
~$ brew install libcouchbase
But I'm getting an error when homebrew tries to install the dependency cmake:

Anyone have any ideas on what I should do? Thanks.

Answer 1

Do you have the latest (available for 10.6.8) version of Xcode and its devtools? It appears to be an issue with GCC (I initially had issues with the LLVM gcc version Apple packages with Xcode).
Try brew install gcc (or brew reinstall gcc if you initially used brew to install gcc) and then run brew install make again.

Answer 2

I've got XCode version 3.2.6 installed, which I believe is the highest version compatible with OSX 10.6.8.
In the gist, whose link I posted, one of the errors is:
error: ncurses/ncurses.h: No such file or directory
I found ncurses.h on my system here:
/usr/include$ ls -al ncurses.h
lrwxr-xr-x 1 root wheel 8 Aug 11 2012 ncurses.h -> curses.h
...which if you note is not in a directory called ncurses(look at the prompt)--ncurses being the directory where the error message says ncurses.h should be. Also, note that ncurses.h is a link to another file: curses.h (see the arrow on the right?). So, I did this:
/usr/include$ sudo mkdir ncurses
Password:
/usr/include$ cd ncurses
/usr/include/ncurses$ sudo cp -av ../ncurses.h . (-a => copy link rather than the file it points to, -v => verbose, show what is being copied)
Password:
../ncurses.h -> ./ncurses.h
/usr/include/ncurses$ ls -al
total 8
drwxr-xr-x 3 root wheel 102 Dec 29 18:59 .
drwxr-xr-x 272 root wheel 9248 Dec 29 18:13 ..
lrwxr-xr-x 1 root wheel 8 Dec 29 18:59 ncurses.h -> curses.h
Then I tried installing libcouchbase again:
~$ brew install libcouchbase

Python SDK
But then I was unable to install the Python SDK following the instructions here:
http://docs.couchbase.com/couchbase-sdk-python-1.2/
$ python -V
Python 2.7.9
I got to here:
5. Install the Python SDK. The easiest way to do this is via the pip tool:
shell> pip install couchbase --quiet
But this is what happened:

I fixed the unicode error by patching the python source code:

#python 2.x patch found here: https://github.com/pypa/pip/issues/1137

But then I got this error:

$
(I just looked at the error log mentioned above: pip.log, and it says the error was a KeyboardInterrupt. Huh? So, I tried $ pip install couchbase --quiet again and it worked. Then, to test the install $ python -c 'import couchbase', and there were no errors! I don't know if the stuff I did below influenced anything.)
Next, I decided to try installing from source:
According to the README file:
~/Downloads/couchbase-1.2.4$ python setup.py build_ext --inplace
But that ended like this:
src/exceptions.c:136: error: too many arguments to function
‘pycbc_exc_map’ lipo: can't figure out the architecture type of:
/var/folders/++/++iEr0qoGaimgUBsnNcijk+++TI/-Tmp-//ccZekvJj.out error:

Next, I did this:
~/Downloads/couchbase-1.2.4$ python setup.py build_ext \
> --library-dir ~/.homebrew/Cellar/libcouchbase/2.4.5_1_gd7f6ecf/lib \

...which ended without error. But testing the install failed:
~/Downloads/couchbase-1.2.4$ python -c 'import couchbase'
Traceback (most recent call last):
File "<string>", line 1, in <module>
File "couchbase/__init__.py", line 18, in <module>

import couchbase.exceptions as E
File "couchbase/exceptions.py", line 18, in <module>
import couchbase._libcouchbase as C
ImportError: No module named _libcouchbase
So, I thought what the heck, I'll go ahead and try this:
~/Downloads/couchbase-1.2.4$ python setup.py install
...
...
Installed /Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/couchbase-1.2.4-py2.7-macosx-10.6-intel.egg

Finished processing dependencies for couchbase==1.2.4
But, I got the same import error when testing the install, so I gave up.
After reading the answer to my question, I did:
$ brew install gcc
but I didn't try to fix couchbase until now. I don't think installing gcc with homebrew did anything because I still get:
