Jonathan Keane commented on ARROW-12785:
----------------------------------------
I can't fully explain why, but something about
[https://github.com/Homebrew/homebrew-core/pull/76984] is triggering gcc to be
installed with brew (which fails to link because there's a macos version of
gfortran in the way).
[The last passing build
does|https://github.com/ursacomputing/crossbow/runs/2563406333] not include gcc
at all:
{code:java}
==> Installing dependencies for apache-arrow: gflags, glog, abseil, protobuf,
re2, grpc, openblas, numpy, rapidjson, snappy and thrift
{code}
But subsequent builds have:
{code:java}
==> Installing dependencies for apache-arrow: gflags, glog, abseil, protobuf,
re2, grpc, gcc, openblas, numpy, rapidjson, snappy and thrift
{code}
For now I'm removing the offending gfortran from the path so that brew will
happily install gcc regardless.
> [CI] Nightly builds can't install GCC and OpenBLAS properly
