Antoine Pitrou commented on ARROW-17110: ---------------------------------------- bq. Can we avoid depending on Abseil ABI by removing Abseil use in {{cpp/src/arrow/filesystem/gcsfs_internal.cc}} and {{{}cpp/src/arrow/filesystem/gcsfs_test.cc{}}}? AFAIU, the problem is that the GCS C++ headers use Abseil, so we depend on the ABI no matter what. [~coryan] Is my understanding right? > [C++] Move away from C++11 > -------------------------- > > Key: ARROW-17110 > URL: https://issues.apache.org/jira/browse/ARROW-17110 > Project: Apache Arrow > Issue Type: Task > Components: C++ > Reporter: H.

This is because the ABI of abseil is sensitive to the C++ standard that's > used to compile, and google only supports a homogeneous version to compile > all artefacts in a stack. This creates some friction with conda-forge (where > the compilers are generally much newer than what arrow might be willing to > impose). For now, things seems to have worked out with arrow > [specifying|https://github.com/apache/arrow/blob/897a4c0ce73c3fe07872beee2c1d2128e44f6dd4/cpp/cmake_modules/SetupCxxFlags.cmake#L121-L124] > C\+\+11 while conda-forge moved to C\+\+17 - at least on unix, but windows > was not so lucky. > Perhaps people would therefore also be interested in collaborating (or at > least commenting on) this > [issue|https://github.com/conda-forge/abseil-cpp-feedstock/issues/29], which > should permit more flexibility by being able to opt into given standard > versions also from conda-forge. -- This message was sent by Atlassian Jira (v8.20.10#820010)
