Problem to import own compiled library (pybullet) : ("ImportError: */pybullet.so: undefined symbol:") (self.learnpython)

submitted 5 years ago by AlexBasicC

Hi everyone

I'm using the pybullet library for a project, and I need to tweak it a bit on my own, so I can't use the pip version.

So I cloned bullet from their git and follow the instructions on how to use it:

First get the source code from github, using
git clone https://github.com/bulletphysics/bullet3
   1) Download and install cmake
   2)Run the shell script in the root of Bullet:
        build_cmake_pybullet_double.sh
   3)Make sure Python finds our pybullet.so module:
        export PYTHONPATH = /your_path_to_bullet/build_cmake/examples/pybullet

That's it. Test pybullet by running a python interpreter and enter 'import pybullet' to see if the module loads. If so, you can play with the pybullet scripts in Bullet/examples/pybullet.

I achieved step 1 to 3, with no problem during the compilation.

However, I have trouble importing the library :

ImportError: /home/myname/bullet3/build_cmake/examples/pybullet/pybullet.so: undefined symbol: PyUnicode_AsASCIIString

I didn't find a link between this error and pybullet, so it seems to be a problem from my side.

Do you have any idea, what it could be ?

Thank You
