Installing py-ldap on Mac OS X Mavericks (missing sasl.h)

Question

I can't seem to be able to get the python ldap module installed on my OS X Mavericks 10.9.1 machine.

Kernel details: uname -a Darwin 13.0.0 Darwin Kernel Version 13.0.0: Thu Sep 19 22:22:27 PDT 2013; root:xnu-2422.1.72~6/RELEASE_X86_64 x86_64

I tried what was suggested here: http://projects.skurfer.com/posts/2011/python_ldap_lion/

But when I try to use pip I get a different error

Modules/LDAPObject.c:18:10: fatal error: 'sasl.h' file not found

*#include sasl.h

I also tried what was suggested here: python-ldap OS X 10.6 and Python 2.6

But with the same error.

I am hoping someone could help me out here.

using pieces from both @hharnisc and @mick-t answers.

pip install python-ldap \
   --global-option=build_ext \
   --global-option="-I$(xcrun --show-sdk-path)/usr/include/sasl"

I don't have sudo permission on mac and this just did the trick ! – attaboyabhipro Oct 21 '14 at 03:20
This worked for me on Yosemite also. I didn't need to install anything macports or homebrew related for this particular install. Thanks! – etteyafed Oct 27 '14 at 04:33

This also works on El Capitan / 10.11 with System Integrity Protection on. – zakx Oct 15 '15 at 16:22

I was running into problems manually creating the link as in @hharnisc's solution (`ln: /usr/include: Operation not permitted`, even as sudo), but this worked on El Capitan. – Chris Vandevelde Oct 26 '15 at 22:00
to fix the issue about permissions and also isolate libraries installation, I suggest using virtualenv: "python -m virtualenv /yoursource; /yoursouhce/bin/pip install blah" this will install everything local to your project and avoid clashing with other projects. – Cross Jul 27 '17 at 09:52
That answer is still valid under Mojave 10.14.3 – Paraita Feb 22 '19 at 02:58

A workaround
/usr/include appears to have moved

$ xcrun --show-sdk-path    
$ sudo ln -s <the_path_from_above_command>/usr/include /usr/include

Now run pip install!

Worked on OSX Mavericks for me. – Casey Jul 25 '14 at 22:34

Worked for me on Yosemite. As a one-liner: ``sudo ln -s `xcrun --show-sdk-path`/usr/include /usr/include``. – juanpaco Nov 05 '14 at 19:06

This no longer works on El Capitan if you have [SIP](https://developer.apple.com/library/mac/releasenotes/MacOSX/WhatsNewInOSX/Articles/MacOSX10_11.html#//apple_ref/doc/uid/TP40016227-DontLinkElementID_19) enabled. The other method (passing `-I` to pip) works. – Brandon LeBlanc Oct 03 '15 at 17:39

In my particular case, I couldn't simply use the pip arguments noted in other answers because I'm using it with tox to install dependencies from a requirements.txt file, and I need my tox.ini to remain compatible with non-Mac environments.

I was able to resolve this in much simpler fashion: exporting CFLAGS such that it adds an include path to the sasl headers already installed by Xcode:

$ pip install python-ldap
    ...
    building '_ldap' extension
    creating build/temp.macosx-10.10-x86_64-2.7
    creating build/temp.macosx-10.10-x86_64-2.7/Modules

    Modules/LDAPObject.c:18:10: fatal error: 'sasl.h' file not found
    #include <sasl.h>
             ^
    1 error generated.
    error: command 'clang' failed with exit status 1

$ export CFLAGS="-I$(xcrun --show-sdk-path)/usr/include/sasl"

$ pip install python-ldap
...
Successfully installed python-ldap-2.4.19

Depending on whether or not you use any userspace-friendly Python tools (I use pyenv), you may have to prefix your pip commands with sudo.

Worked for me in OS X Yosemite. Thanks! – trungly Oct 09 '15 at 19:18 — trungly, Oct 09 '15 at 19:18

I had the same problem. I'm using Macports on my Mac and I have cyrus-sasl2 installed which provides sasl.h in /opt/local/include/sasl/. You can pass options to build_ext using pip's global-option argument. To pass the include PATH to /opt/local/include/sasl/sasl.h run pip like this:

pip install python-ldap --global-option=build_ext --global-option="-I/opt/local/include/sasl"

Alternatively you could point it to whatever the output from xcrun --show-sdk-path provides. On my box that's: /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.9.sdk

Then you need to determine the PATH to the sasl header files. For me that's:

/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.9.sdk/usr/include/sasl/

Let me know if that helps or you need a hand.

I used a combination of posts I found about this problem (including this one) to eventually come up with this (copied from a larger script):

export XC_SDK=$(xcrun --show-sdk-path)
export USR_INC=$XC_SDK/usr/include
export PATH=$USR_INC:$PATH

echo "installing python-ldap"
ARCHFLAGS=-Wno-error=unused-command-line-argument-hard-error-in-future pip install python-ldap

You can test it with python -c "import ldap"

The main reason I didn't follow the advice of @hharnisc was that on my local machine /usr/local had not moved, so I just temporarily put $XC_SDK before it on the path, and that seems to work.

I got this error when running buildout.

I fixed it, first finding the sasl.h file:

mdfind -name sasl.h

then defining the corresponding CFLAGS environment variable:

export CFLAGS="-I/opt/local/include/sasl"

and finally running buildout again.
