Philipp Moritz created ARROW-5751:
-------------------------------------
Summary: [Packaging][Python] Python 2.7 wheels broken on macOS:
libcares.2.dylib not found
Key: ARROW-5751
URL: https://issues.apache.org/jira/browse/ARROW-5751
Project: Apache Arrow
Issue Type: Improvement
Reporter: Philipp Moritz
I'm afraid while [https://github.com/apache/arrow/pull/4685] fixed the macOS
wheels for python 3, but the python 2.7 wheel is still broken (with a different
error):
{code:java}
ImportError:
dlopen(/Users/pcmoritz/anaconda3/lib/python3.6/site-packages/pyarrow/lib.cpython-36m-darwin.so,
2): Library not loaded: /usr/local/opt/c-ares/lib/libcares.2.dylib
Referenced from:
/Users/pcmoritz/anaconda3/lib/python3.6/site-packages/pyarrow/libarrow_python.14.dylib
Reason: image not found{code}
I tried the same hack as in [https://github.com/apache/arrow/pull/4685] for
libcares but it doesn't work (removing the .dylib fails one of the earlier
build steps). I think the only way to go forward on this is to compile grpc
ourselves. My attempt to do this in
[https://github.com/apache/arrow/compare/master...pcmoritz:mac-wheels-py2]
fails because OpenSSL is not found even though I'm specifying the
OPENSSL_ROOT_DIR (see
[https://travis-ci.org/pcmoritz/crossbow/builds/550603543]). Let me know if you
have any ideas how to fix this!
