如何通过构建安装Readline

Question

I would like to configure my python project to automatically build postgresql in installation process. You can do it similar to what's described here:

Buildout, psycopg2, postgresql

The problem is I don't like using

configure-options =
--without-readline

option

That means I have to install readline library. I looked at plone configuration files in I found some hints, so I added these parts to my buildout.cfg:

[readline-patch]
recipe = z3c.recipe.runscript
url = http://ftp.gnu.org/gnu/readline/readline-5.2-patches
install-script = ${buildout:directory}/bin/fetch-readline-patches.py:fetch
update-script = ${readline-patch:install-script}

[readline]
recipe = zc.recipe.cmmi
url = http://ftp.gnu.org/gnu/readline/readline-5.2.tar.gz
patch = ${readline-patch:prefix}/readline.patch
extra_options =
    --prefix = ${buildout:parts-directory}/opt

But now, I'm getting this error:

Installing readline-patch.
While:
  Installing readline-patch.

An internal error occurred due to a bug in either zc.buildout or in a
recipe being used:
Traceback (most recent call last):

    self.callScript(script)

    module = imp.load_source('script', filename)
IOError: [Errno 2] No such file or directory

Any help with making it working would be appreciated.

The z3c.recipe.runscript does not have an url option. So the script will not be downloaded. You can use a local script, which will download the file and execute it. Or use http://pypi.python.org/pypi/collective.recipe.scriptgen to make a script by buildout which will download the file via ie curl
