--------------------------------------------------------
Hmm I don't understand. How are bindings supposed to use `libarrow.a` if it
depends on internal vendored libraries which are not shipped with the
installation? There is no way to link to this?
It seems to me you either need to include the internal libdouble-conversion
object files into `libarrow.a`, or alternatively ship libdouble-conversion.a
along with libarrow.a in the installation (perhaps rename to
libarrow_double-conversion.a) and update arrow.pc to link with "-larrow
-ldouble-conversion"
Shared libs (dll files) are not permitted in R so we need a complete static
build of libarrow.

> URL: https://issues.apache.org/jira/browse/ARROW-4844
> Project: Apache Arrow
> Issue Type: Bug
> Components: C++
> Affects Versions: 0.12.1
> Reporter: Jeroen
> 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.
