> Key: ARROW-4809
> URL: https://issues.apache.org/jira/browse/ARROW-4809
> Project: Apache Arrow
> Issue Type: Bug
> Components: Python
> Affects Versions: 0.11.1
> Environment: RHELS 6.10; Python 3.7.2
> Reporter: David Schwab
> Priority: Blocker
>
> I installed conda 4.5.12 and created a new environment named test-env. I
> activated this environment and installed several packages with conda,
> including pyarrow. When I run a Python shell and import pyarrow, I get the
> following error:
>
> {code:java}
> Traceback (most recent call last):
> File "<stdin>", line 1, in <module>
> File "/test-env/lib/python3.7/site-packages/pyarrow/__init__.py", line 54,
> in <module>
> from pyarrow.lib import cpu_count, set cpu_count
> Import Error:
> /test-env/lib/python3.7/site-packages/pyarrow/lib.cpython-37m-x86_64-linux-gnu.so:
> undefined symbol: _ZNK5arrow6Status8ToStringB5xcc11Ev
> {code}
> From Googling, I believe this has to do with the compiler flags used to build
> either pyarrow or one of its dependencies (libboost has been suggested); I
> can build the package from source if I need to, but I'm not sure what flags I
> would need to set to fix the error.
