Hello,

I am unable to get the boost:python embedding tutorials to work. I have the exact same problems as in this unanswered post:

http://www.nabble.com/boost.python-embedding-tutorial-doesn%27t-work---td176...

Basically, commands like this

python::object ignore = python::exec("print len([1,2,3])", main_namespace);

fail with

Traceback (most recent call last): File "<string>", line 1, in <module> TypeError: 'NoneType' object is unsubscriptable

whereas simpler commands like this do work:

python::object ignoreme = python::exec(python::str("print 5"), main_namespace);

Similar problems occur with eval instead of exec, for some uses the error is instead

TypeError: 'NoneType' object does not support item assignment

If it's important, I am running Ubuntu 8.04, Python is 2.5.2, Boost is 1.34.1.

Thanks in advance for any tips.

Kripken, Could you please submit a ticket describing the problem at http://svn.boost.org? Thanks, -- Dave Abrahams BoostPro Computing http://www.boostpro.com
