Antoine Pitrou updated ARROW-17110:
-----------------------------------
Summary: [C++] Move to C++17 (was: [C++] Move away from C++11)
> [C++] Move to C++17
> -------------------
>
> Key: ARROW-17110
> URL: https://issues.apache.org/jira/browse/ARROW-17110
> Project: Apache Arrow
> Issue Type: Task
> Components: C++
> Reporter: H. Vetinari
> Priority: Major
>
> The upcoming abseil release has dropped support for C++11, so
> {_}eventually{_}, arrow will have to follow. More details
> [here|https://github.com/conda-forge/abseil-cpp-feedstock/issues/37].
> Relatedly, when I
> [tried|https://github.com/conda-forge/abseil-cpp-feedstock/pull/25] to switch
> abseil to a newer C++ version on windows, things apparently broke in arrow
> CI. 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.
