Re: [Python.NET] glibc invalid pointer when importing clr

17 Oct 2014

      Hi,

probably your python has not been compiled with --enable-shared, and so it
ends up loading the python core twice (once in the executable, and again in
the so referenced by the pythonnet module). This means that the one
pythonnet is using doesn't get initialized correctly.

You could try building python yourself with --enable-shared. Here are some
instructions (there are loads of others, I just found this on google):
http://du-alter-schwede.azurewebsites.net/index.php/2012/07/26/how-to-build-...

Otherwise you could use the npython binary that builds as part of the
pythonnet project.

You might also want to try the latest version of the pythonnet code from
the develop branch on github. It's got a Travis CI build so does get built
and tested on linux (ubuntu not debian though) - although you should be
able to get the svn code working too.
https://github.com/pythonnet/pythonnet
https://travis-ci.org/pythonnet/pythonnet/builds

cheers,
Tony

Hi!
First, sorry for my English. I'm trying to use pythonnet on Debian Wheezy.
I'm checkout svn trunk, when install mono-2, and other dependencies.
Building clr.so done without errors. On the next step I'm put clr.so,
Python.Runtime.dll and Python.Runtime.dll.config in
/usr/local/lib/python2.7/dist-packages.
But when I'm try to use this, I'm got such traceback:
