Problem installing lxml / etree

Question

I've installed lxml, but I get an error when I try to use lxml.html.clean.clean_html:

>>> from lxml.html.clean import clean_html
Traceback (most recent call last):
  File "<console>", line 1, in <module>
  File "/home/anarres/lib/python2.7/lxml-2.3-py2.7-linux-i686.egg/lxml/html/__init__.py", line 12, in <module>
    from lxml import etree
ImportError: /home/anarres/lib/python2.7/lxml-2.3-py2.7-linux-i686.egg/lxml/etree.so: undefined symbol: libiconv

It seems there is a problem with the etree module. Any ideas of how to fix this?

Answer 1

In reply to David, I installed lxml like this:

$ mkdir $HOME/tmp     
$ export TEMP=$HOME/tmp     
$ CFLAGS="$CFLAGS -lgcrypt -fPIC" STATIC_DEPS=true easy_install-2.7

A lot of code ran down the screen and then I got a message that the file /home/anarres/lib/python2.4/lxml-2.3-py2.7-linux-i686.egg had been created. So I did this:

$ easy_install /home/anarres/lib/python2.7/lxml-2.3-py2.7-linux-i686.egg

And I got the following response:

Processing lxml-2.3-py2.7-linux-i686.egg     
Copying lxml-2.3-py2.7-linux-i686.egg to /home/anarres/lib/python2.4     
Removing lxml 2.3 from easy-install.pth file Adding lxml 2.3 to easy-install.pth file

Answer 2

Thanks, per the suggestion from Johns I tried to install lxml to python-2.7, but I'm still getting the same problem. I did this:

$ easy_install-2.7 /home/anarres/lib/python2.7/lxml-2.3-py2.7-linux-i686.egg

and got this response:

Processing lxml-2.3-py2.7-linux-i686.egg
lxml 2.3 is already the active version in easy-install.pth

Installed /home/anarres/lib/python2.7/lxml-2.3-py2.7-linux-i686.egg

But when I try to import etree I still get an error.

>>> from lxml import etree
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: /home/anarres/lib/python2.7/lxml-2.3-py2.7-linux-i686.egg/lxml/etree.so: undefined symbol: libiconv

Remove the current egg and than use a different egg or the default egg,
