where can I find libstdc++.so.6 with support for GLIBCXX_3.4.21

Question

I try to install pandas with berryconda and the 'import pandas as pd' in python return me this error:

ImportError: /usr/lib/arm-linux-gnueabihf/libstdc++.so.6: version `GLIBCXX_3.4.21' not found (required by /home/pi/berryconda3/lib/python3.6/site-packages/pandas/_libs/window.cpython-36m-arm-linux-gnueabihf.so).

OS is an up-to-date Jessie. Use of berryconda is due to the very old release of pandas in Jessie repository.

Answer 1

Option 1:

After following the direction on pandas' GitHub issues page which states:

I confirmed that with pandas==0.22, there is no problem.

I tried this and success!

At the time of this answer, Miniconda on RasPi only supports up to Py3.6, so stepping back to 0.22.0 from 0.23.4, wasn't a huge issue (to me).

Option 2:

If you don't want to rollback the version of pandas, I found this answer on askubuntu very helpful. I reinstalled pandas 0.23.4 and followed these instructions and all is well!

Basically:

• Find a later libstdc++.so.6.x.x file
• Copy it to /usr/lib/arm-linux/gnueabihf
• Create a symlink to libstdc++.so.6

In my case, I found a later version on a RasPi4, and copied it onto the Jessie box.
