On a server, for disk optimization, we do not install a C compiler, and here is the problem :
I want to install 'spur' python package with buildout 2.3.1 , spur is using pycrypto which requires a C compiler.
To avoid compilation, I installed on the server (Suse 11SP2) the rpm python-pycrypto (python-pycrypto-2.6-31.7.x86_64.rpm). I can check with 'pip freeze' that pycrypto is installed :
pip freeze
lxml==2.1.2
mod-python==3.3.1
Numeric==24.2
numpy==1.3.0
pycrypto==2.6
pywbem==0.7.0
PyXML==0.8.4
Nevertheless, when I start buildout, it still tries to build pycrypto with a C compiler that does not exist.
So I added include-site-packages = true and allowed-eggs-from-site-packages = pycrypto in buildout.cfg, but they are not taken in account. I also tried to do a :
python bootstrap.py --allow-site-packages
bin/buildout
but that did not help too.
What can I do to avoid buildout compile a package that is already compiled and installed from rpm ?
Here is the buildout.cfg
[buildout]
newest = false
extensions = gp.vcsdevelop
develop-dir = src
parts = eggs tests wsgi
include-site-packages = true
allowed-eggs-from-site-packages = pycrypto
eggs =

...
and the logs :

RuntimeError: autoconf error
An error occurred when trying to install pycrypto 2.6.1. Look above this message for any errors that were output by easy_install.

Error: Couldn't install: pycrypto 2.6.1
I found a workaround :
I just created a egg-link file into develop-eggs dir :
$ cat develop-eggs/pycrypto.egg-link
/usr/lib64/python2.6/site-packages
I got no evidence that zc.buildout > 1.7.1 supports include-site-packages
, nor allowed-eggs-from-site-packages
.
On my local machine I searched for the mentioned features in the following versions of zc.buildout:
Check Readme on https://pypi.python.org/pypi/zc.buildout/1.7.1 . The features were introduced somewhere around zc.buildout 1.5.0. The last release, which supports those features is 1.7.1.
They made some kind of relaunch with zc.buildout 2.0.0...
Quote from the changlog, version 2.0.0:
This is a backward incompatible release of buildout that attempts to correct mistakes made in buildout 1.
Buildout no-longer tries to provide full or partial isolation from system Python installations. If you want isolation, use buildout with virtualenv, or use a clean build of Python to begin with.
In your case this means, if you want to use those features you need to use zc.buildout 1.7.1
.
It's also important, that it's not possible to use both options at the same time. Use allowed-eggs-from-site-packages (only specific packages)
, or include-site-packages
.
I assume you're using the boostrap.py version 1: http://downloads.buildout.org/1/bootstrap.py
This version does not support the ´--allow-site-packages´ options, since it was intended to use with zc.buildout 1.x, which handles this case (or at least 1.5.x).
Well, after this short trip in buildout history, I guess the following two points will solve your problem:
--allow-site-packages
option. Then python bootstrap.py --allow-site-packages
works as expected.
