Dear all, how do you think _GLIBCXX_USE_CXX11_ABI should be set for manylinux2014 (and manylinux2010) wheels? Should it be 0 or 1? Unfortunately I don't see https://www.python.org/dev/peps/pep-0599/ or https://github.com/pypa/manylinux specifying it. I think for manylinux1 the common wisdom was to set it to 0. It would then also make sense to have the same setting for the later wheels since the manylinux* wheels are supposed to be compatible with each other. Which is a bummer since that means we cannot use the new ABI (and std::list::size() is O(n) in the old one as far as I know).
My understanding is that PyTorch is setting it to 0 (based on https://github.com/pytorch/pytorch/issues/51039) and so does TensorFlow ( https://github.com/tensorflow/tensorflow/blob/5dcfc51118817f27fad5246812d83e5dccdc5f72/tensorflow/tools/dockerfiles/tests/build-cpu.sh#L35). It looks like in Arrow we are setting it to 1 since https://github.com/apache/arrow/commit/de7198274a3a2c90af765d55838e4f4339bae84f . It would be great to have some clarity around this in the community and make sure we all use the same setting to avoid subtle incompatibilities. I'm specifically asking because in Ray we are currently deciding on how it should be set (see https://github.com/ray-project/ray/pull/18273). Thanks in advance for your input! Best, Philipp.
