r1990: AttributeError: 'Boost.Python.StaticProperty' object attribute '__doc__' is read-only

[Anton Gladky]

When I start YADE, I get:

...

Looks similar to bug #416335 in yade, i.e. duplicate of bug #457688; can you try the solution proposed there (boost::python from ppa)? Is your karmic(or other version?) installation up-to-date? My computer runs karmic and I have not this issue.

Besides, the double registration of OpenGLRenderingEngine and Srializable suggests there might be old module being loaded, is your installation clean?

Cheers, Vaclav

[Anton Gladky (gladky-anton)]

Yes, my Karmic is always updated and the installation is clean.
The problem appeared only in 1990 revision. 1989 works without errors.

I have just tried to compile r1990 on another machine, and it gives the same result.

[Václav Šmilauer (eudoxos)]

Can you try https://bugs.launchpad.net/ubuntu/+source/boost1.38/+bug/457688/comments/6 , if that helps?

[Anton Gladky (gladky-anton)]

Ok, thank you. It helped.

As I understand in Lucid default boost will be at least 1.40

But now, I think we should add this workaround somewhere.
Where is it better to so it? What do you think?

[Václav Šmilauer (eudoxos)]

r1991 detects the issue and tells the user what to do.

[Václav Šmilauer (eudoxos)]

Fixed by boost::python in karmic-updates
