Neal Richardson commented on ARROW-5470:
----------------------------------------
Update: it wasn't the env var:
[https://travis-ci.org/nealrichardson/arrow/jobs/539794848]
Next theory: OS/library version. R is using Trusty while GLib is on Xenial, so
there are these version differences:
GLib:
-- Building using CMake version: 3.12.4
-- The C compiler identification is GNU 5.4.0
-- The CXX compiler identification is GNU 5.4.0
-- BOOST_VERSION: 1.67.0
(but later)
-- Boost version: 1.58.0
R:
-- Building using CMake version: 3.9.2
-- The C compiler identification is GNU 4.8.4
-- The CXX compiler identification is GNU 4.8.4
-- BOOST_VERSION: 1.67.0
(but later)
-- Boost version: 1.54.0
> [CI] C++ local filesystem patch breaks Travis R job

> https://issues.apache.org/jira/browse/ARROW-3144 changed a C++ API and
> required downstream bindings to be updated. Romain wasn't immediately
> available to update R, so we marked the R job on Travis as an "allowed
> failure". That failure looked like this:
> [https://travis-ci.org/apache/arrow/jobs/538795366#L3711-L3830] The C++
> library built fine, but then the R package failed to build because it didn't
> line up with what's in C++.
> Then, the C++ local file system patch
> (https://issues.apache.org/jira/browse/ARROW-5378) landed. Travis passed,
> though we were still ignoring the R build, which continued to fail. But, it
> started failing differently. Here's what the R build failure looks like on
> that PR, and on master since then:
> [https://travis-ci.org/apache/arrow/jobs/539207245#L2520-L2640] The C++
> library is failing to build, so we're not even getting to the expected R
> failure.
> For reference, the "C++ & GLib & Ruby w/ gcc 5.4" build has the most similar
> setup to the R build, and it's still passing. One difference between the two
> jobs is that the GLib one has `ARROW_TRAVIS_USE_VENDORED_BOOST=1`, which
> sounds related to some open R issues, and `boost::filesystem` appears all
> over the error in the R job.
