paleolimbot opened a new pull request, #37147:
URL: https://github.com/apache/arrow/pull/37147
### Rationale for this change
Currently a naive `install.packages("arrow")` will result in a failed build
if gcc-13 is the compiler. This is because we include GCS by default on this
type of build (bundled). CRAN's check farm includes at least one system where
gcc-13 is the compiler and so we need can't error or suggest a user workaround.
### What changes are included in this PR?
This PR explicitly sets the relevant environment variable if the compiler
string contains "gcc" and if `gcc --version` contains "13.XXX.XX". This is
admittedly crude; however, the alternative of updating Abseil results in a
cascading set of changes that may break other parts of Arrow. Few if any actual
users will build the Arrow R package from source using gcc-13, so this has a
much lower footprint (and a workaround: you can just set the GCS environment
variable yourself before building if you do, in fact, want to attempt this).
### Are these changes tested?
Tested via crossbow (see below).
### Are there any user-facing changes?
No.
