--------------------------------------
Summary: [R] [Packaging] Developing + {LIBARROW_BINARY=true}
Key: ARROW-12008
URL: https://issues.apache.org/jira/browse/ARROW-12008
Project: Apache Arrow
Issue Type: Improvement
Components: Packaging, R
Reporter: Jonathan Keane
As far as I can tell from reading configure + nixlibs.sh, if one tries to use
{LIBARROW_BINARY=true}} on a source checkout there really isn't a binary to be
found to install. The installation process does mention that a binary isn't
found + it will build from source.
I don't know that we need to support installing a binary from a development
branch (afterall, it's entirely possible libarrow would no longer be compatible
with the r package) but I think we should fail a little bit more loudly (or
express that the binary install will not be attempted because it looks like one
is building from a source checkout (possibly detected by seeing if the version
is ~x.x.x.9000)).
Alternatively, we could add date-guessing and attempt to download the nightly
libarrow corresponding to that.
