Jeffrey Wong created ARROW-4316:
-----------------------------------
Summary: Reusing arrow.so for both Python and R
Key: ARROW-4316
URL: https://issues.apache.org/jira/browse/ARROW-4316
Project: Apache Arrow
Issue Type: Bug
Components: Python, R
Affects Versions: 0.12.0
Environment: Ubuntu 16.04, R 3.4.4, pyarrow 0.12, cmake 3.12
Reporter: Jeffrey Wong
My team uses both pyarrow and R arrow, we'd like both libraries to link to the
same arrow.so file for consistency. pyarrow ships both arrow.so and parquet.so,
if I can reuse those .so's to link R that would guarantee consistency.
Under arrow v0.11.1 I was able to link R against libarrow.so found under
pyarrow by passing LIB_DIR to the R [configure
file|https://github.com/apache/arrow/blob/master/r/configure]. However, in
v0.12.0 I am no longer able to do that. Here is a reproducible example on
Ubuntu 16.04 which produces the error:
Reproducible example:
# get the parquet headers which are not shipped with pyarrow
