Jeroen commented on ARROW-4844:
-------------------------------
OK thank you. FWIW: I was able to make the R bindings work by building an
external libdouble-conversion, and then rebuilding libarrow using this external
library by setting -DDOUBLE_CONVERSION_HOME. By avoiding the vendored library,
I can now statically link with libarrow by also including `-ldouble-conversion`.
Still, I do think that when arrow does get built with vendored libs, those
should be shipped one way or another. Otherwise there is no way to link with
the resulting libarrow library.

> Key: ARROW-4844
> URL: https://issues.apache.org/jira/browse/ARROW-4844
> Project: Apache Arrow
> Issue Type: Bug
> Components: C++
> Affects Versions: 0.12.1
> Reporter: Jeroen
> Assignee: Uwe L. Korn
> Priority: Major
>
> When trying to statically link the R bindings to libarrow.a, I get linking
> errors which suggest that libdouble-conversion.a was not properly embedded in
> libarrow.a. This problem happens on both MacOS and Windows.
