I'm super lost trying to work out what to do with this. I've tried
installing a version of the R package which has the build flags changed in the
case of Raspberry Pi for the R package. I've created a .tar.gz file and the
installed it via `install.packages("arrow.tar.gz", repos = NULL, type =
"source")`. This results in the successful installation of the R package, but
no C++ installation - so the atomic issue is fixed I guess.
The lack of successful C++ installation is due to the code in
`tools/nixlibs.R` which uses the R package version to try to install the
correct released version of Arrow and fails if it ends in `.9000`, which is the
version number in the dev R package.
I've tried taking the released version of Arrow 4.0.1 and just updating the
`configure` script to include the above lines, and the ones I added to add the
`-latomic` flag. This successfully install the R package *and* retrieves the
C++ package (I am waiting to see if it installs it properly - it's currently
building but it'll take a while).
I have no idea how I'd add in the change from
https://github.com/apache/arrow/pull/10626 given the current setup, unless I
suppose I was manually installing the C++ libraries myself and then setting up
the R install to look at these.
It's been a while since I looked at it, but I'm pretty sure the change I
made to add the `-latomic` flag to the R build worked fine previously with an
existing Arrow C++ installation.
I'm a bit lost in the above conversation, but it sounds like what is going
on here is:
- the atomic library being missing is the main focus here. It can be
achieved via R _but_ the correct way to do it is via the changes in the PR
mentioned above
- I need to test out whether the changes in the PR mentioned above work to
install things on the Pi (_without_ the changes I made, as these are supposed
to be _instead_ of those not _as well as_ those)
- so I need to build the Arrow C++ library with the changes suggested above
by @kou , and all being well, the R package should the install successfully
without me adding the -latomic flag
