[lxml-dev] lxml 2.0.1 released
Hi all, lxml 2.0.1 is out, changelog follows as usual. The most important changes may actually be the clean-up of the generated API documentation, including loads of added doc-strings all over the place. Have a look at it here: http://codespeak.net/lxml/api/index.html More documentation patches will definitely be appreciated! Have fun, Stefan 2.0.1 (2008-02-13) Features added * Child iteration in lxml.pyclasslookup. * Loads of new docstrings reflect the signature of functions and methods to make them visible in API docs and help() Bugs fixed * The module lxml.html.builder was duplicated as lxml.htmlbuilder * Form elements would return None for form.fields.keys() if there was an unnamed input field. Now unnamed input fields are completely ignored. * Setting an element slice in objectify could insert slice-overlapping elements at the wrong position. Other changes * The generated API documentation was cleaned up and disburdened from non-public classes etc. * The previously public module lxml.html.setmixin was renamed to lxml.html._setmixin as it is not an official part of lxml. If you want to use it, feel free to copy it over to your own source base. * Passing --with-xslt-config=/path/to/xslt-config to setup.py will override the xslt-config script that is used to determine the C compiler options.

This information is definitely not enough for me to get an idea about what happens here. That said, could you try passing the "--auto-rpath" option to setup.py when building? I'd like to know if that makes a difference. You should then see an option "rpath" (or "install_name"??) in the gcc command line. And please also make sure that the "xslt-config" that setup.py finds is the one that comes with the updated libxml2/libxslt libraries, *not* the one pre-installed on your system. Stefan
Hi, I tried passing --auto-rpath to setup.py, but rpath didn't came up in gcc line. xslt-config seems right one for me because this seemed using /opt/local's ones.
