Antoine Pitrou commented on ARROW-18255:
----------------------------------------
While I don't know about "armv6" specifically, I agree that we should probably
not error out just because the architecture is unknown.

> [C++] Support armv6
> -------------------
>
> Key: ARROW-18255
> URL: https://issues.apache.org/jira/browse/ARROW-18255
> Project: Apache Arrow
> Issue Type: Improvement
> Components: C++
> Affects Versions: 10.0.0
> Reporter: Maarten Pronk
> Priority: Major
>
> Over at [https://github.com/JuliaPackaging/Yggdrasil/pull/5425,] we
> cross-compile Arrow to make it easily available within the Julia ecosystem.
> This will for example enable a GDAL with Arrow/Parquet driver support that
> can be installed for everyone.
> We noticed when going from v9 to v10, `armv6` (or any non-defined cpu
> architecture really) now gives an error when compiling. The change is in
> `cpp/cmake_modules/SetupCxxFlags.cmake`. We now patch the code by giving
> armv6 the same status as armv7, which seems to work.
> Would it be possible to not error out on unknown platforms? A warning with
> this platform is not officially supported could be an alternative. Or, the
> other way, you could confirm that armv6 (and others) are just _really_
> unsupported (as in probably breaking) and we should not attempt to compile
> for those platforms?
