Installing python-ldap with buildout and a system installed OpenLDAP

In our use of buildout, we try not to compile every dependent library that is needed. One example of this is LDAP. Instead of putting the responsibility of upgrading OpenLDAP on the buildout, we depend on the OS specific package managers to take care of this. There are several reasons you would want to do this:

  • Upgrading does not require any changes to your application's build
  • OS specific patches will be applied
  • OS specific configuration arguments will be handled by the package manager
  • Dependencies will be handled by the package manager

If you are using zc.buildout, then you can use the zc.recipe.egg recipe to ensure the package gets the proper library paths. Right now, if you try to install python-ldap on FreeBSD, you will get an error.

The most import lines to take note of here are the following:

include_dirs: /usr/local/openldap-2.3/include /usr/include/sasl
library_dirs: /usr/local/openldap-2.3/lib
Modules/errors.h:8:18: error: lber.h: No such file or directory
Modules/errors.h:9:18: error: ldap.h: No such file or directory
Modules/LDAPObject.c:18:18: error: sasl.h: No such file or directory

This means that when pip was trying to install python-ldap, it could not find the dev headers necessary to build the C extensions. Most of the time, this just means that you need to install the appropriate library-dev package, but in this case, I already have the headers available in /usr/local/include.

The solution in this case is to use zc.recipe.egg to install the python-ldap egg for us. This will allow us to define extra paths to look in for the header files.

[buildout]
parts =
    ...
    python-ldap

[python-ldap]
recipe = zc.recipe.egg:custom
egg = python-ldap
include-dirs =
    /opt/local/include
    /opt/local/include/sasl
    /usr/local/include
    /usr/local/include/sasl
    /usr/include
    /usr/include/sasl
library-dirs =
    /opt/local/lib
    /opt/local/lib/sasl2
    /usr/local/lib
    /usr/local/lib/sasl2
    /usr/lib
    /usr/lib/sasl2
rpath = ${:library-dirs}

Now you can use this egg by referencing the python-ldap part as follows:

[instance]
...
eggs =
    ...
    ${python-ldap:egg}

This allows you to rely on your package manager to keep the LDAP libraries up to date.
