Cython installation warning on Mac OS X 10.9.4 - python

I am trying to install the Cython package for Python 2.7.5. I am getting this output when running setup.py from the source code: (After it hits this warning it freezes)

The same thing happens when I use pip to install. Any help would be greatly appreciated! Thanks

OSx Mavericks Python-LDAP pip install failing [duplicate]

It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. For help clarifying this question so that it can be reopened, visit the help center.
Closed 11 years ago.
So I got the latest python-ldap from source. I am also running the source compiled version of python 2.7.2 and I am running this on RHEL. So when I try to compile the package I get this long error message as seen below. So I installed the openldap-devel package and now it is a much smaller error. But still not compiling.

Since this is closed because the question, this doesnt ocmpile please help me out is not a question. I figured it out. I had to manually compile the latest ldap, berkleydb, and then do a build install with it. Then it built fine
The first and second error message state that you're missing lber.h and ldap.h. This is a strong pointer to a missing or invalid openldap-devel package. Do you you have that package (or a similar one matching *ldap-dev*) installed?
Possibly a mismatch in the OpenLDAP and python-ldap versions. Try to compile the latest python-ldap version against a decent version of OpenSSL. E.g. Debian systems have notorious old versions of OpenLDAP installed...

Centos 5 Python 2.7, Cannot install Python-LDAP

I need to install
* Python-LDAP
to run under Ptython 2.7
I have a Centos 5.8 system (I cannot upgrade to 6.x). I currently have Python 2.4 installed and also Python 2.7. I am using Python 2.7 for development (along with Django). I have Python-LDAP installed and working under Python 2.4 (it was installed using yum). I need to install Python-LDAP for use with Python 2.7 (I will also install Django-ldap). I have been trying for days to do this. yum only runs under Python 2.4 so I cannot use that. I downloaded the Python-LDAP source (python-ldap-2.4.13.tar.gz (md5) from https://pypi.python.org/pypi/python-ldap/ but when I try to build it I get errors (see below).
Does anyone know if/how I can install Python-LDAP for Python 2.7 on Centos 5?

I then looked over at this thread: https://mail.python.org/pipermail/python-ldap/2011q2/002937.html
So I downloaded the latest OpenLDAP and got:
./configure
Configuring OpenLDAP 2.4.38-Release ...
...
configure: error: BerkeleyDB version incompatible with BDB/HDB backends
Seems like I'm just sinking lower into a black hole...
This worked in centos 5.10 and python 2.7.6. I installed into a virtualenv.
I see mentions of evolution-openldap in your logs which were in mine when I had the same issue. Those directories are installed by openldap 2.3x.
You don't need to build openldap from source as there is a version in yum that is new enough to satisfy the version requirement by python-ldap.
openldap24-libs.i386 2.4.23-5.el5
openldap24-libs.x86_64 2.4.23-5.el5
openldap24-libs-devel.i386 2.4.23-5.el5
openldap24-libs-devel.x86_64 2.4.23-5.el5
To install you should first yum install openldap24-libs openldap24-libs-devel.
edit setup.cfg so its [_ldap] section so it contains:
library_dirs = /usr/lib/openldap24
include_dirs = /usr/include/openldap24
Run the build again. (I deleted my old build/ directory, you probably don't need to but give that a shot if the above is not working).

You probably need Xcode's Command Line Tools.
Download the lastest version of Xcode, then go to "Preferences", select "Download" tab, then install Command Line Tools.

What is the meaning of this ImportError when importing a Cython generated .so file?

I am walking through the Cython documentation and building each of the example apps. I'm a little stuck at Using C Libraries. After successfully building the .so file and attempting to import it in a python file called test.py the following error is thrown.
$ python3.2 test.py
Traceback (most recent call last):
File "test.py", line 12, in <module>
from queue import Queue
ImportError: dlopen(/Users/jeremy/Development/labs/python/cython_lib_wrapper/queue.so, 2): Symbol not found: _queue_free
Referenced from: /Users/jeremy/Development/labs/python/cython_lib_wrapper/queue.so
Expected in: flat namespace
in /Users/jeremy/Development/labs/python/cython_lib_wrapper/queue.so
The .so file sits right next to the test.py file. So, it seems as though it should be found.
This is running the latest version of Cython, with Python 3.2 on a OSX 10.6.
Any insights?

EDIT:
Ah, you didn't mention you had a dependency on the code in libcalg. That stuff needs to be compiled and included when you build the cextension.
Just modify setup.py:
# setup.py
# ...
ext_modules = [Extension("queue", ["queue.pyx", "libcalg/queue.c"])]
# ...
We could step back and see if you can build a really simple example:
I've tried the following (3 files, myext.pyx, test.py, setup.py) and it appears to work fine. Of course I'm on OS X 10.7 so it's not exactly the same as your environment. To rule out differences perhaps you can copy these and build them as a sanity check.
Contents of myext.pyx:
# myext.pyx
def square(x):
return x * x
Contents of test.py
# test.py
from myext import square
print "%d squared is %d"%(4, square(4))
Contents of setup.py:
# setup.py
from distutils.core import setup
from distutils.extension import Extension
from Cython.Distutils import build_ext
ext_modules = [Extension("myext", ["myext.pyx"])]
setup(
name = 'Hello world app',
cmdclass = {'build_ext': build_ext},
ext_modules = ext_modules
)

Homebrew works great for me. To install GDAL 1.9 with Homebrew all you have to do is
brew install gdal
Homebrew requires xcode, and I think commandline tools. More information can be found here
How about using the precompiled binaries available from http://www.kyngchaos.com/software/frameworks
Also, are you using 1.7.1 for a specific reason? 1.8.1 is, I believe, the current release build.
Caveat: I do not know if Lion is yet supported by the GDAL OSX binaries.
Did you actually install Xcode 4.1 on 10.7? Downloading it from the App Store is not enough; you have to manually run the Installer which it downloads to /Applications.
If you actually want to build from source, but want a convenient way to install there is a gdal package available from MacPorts - just install MacPorts, then on the command line type:
port install gdal
Macports will fetch and compile the source code for you. As of the time of writing the version in MacPorts is 1.9.0
for installing GDAL on mac:
brew install gdal
and then
pip install gdal
solved this for me
