Project: Apache Arrow
Issue Type: Improvement
Components: Python
Reporter: Krisztian Szucs
Assignee: Krisztian Szucs
Fix For: 0.15.0
The PR https://github.com/apache/arrow/pull/4886 aimed to link zlib statically
with the wheels broke the windows wheels. This issue was hidden by the AppVeyor
wheel build script, but recent conda changes have reproduced the issue caused
the broken windows wheels for 0.14.1
https://github.com/ursa-labs/crossbow/branches/all?query=nightly-2019-09-17-0-appveyor-wheel-win-cp37m
The root cause was, thad ZLIB was linked dynamically in the windows wheels
despite `zlib_SOURCE=BUNDLED`.
