Hi, We require CMake 3.5+ now because Ubuntu 18.04 ships 3.5. We dropped support for Ubuntu 18.04 because it reached EOL.
Can we require CMake 3.16+ in Apache Arrow C++ 13.0.0? Here are CMake versions of our supported platforms: * Ubuntu 20.04: CMake 3.16 * CentOS 7: CMake 3.17 * Debian GNU/Linux bullseye: 3.18 * Amazon Linux 2: CMake 3.13!!! See the Amazon Linux 2 item. It ships CMake 3.13 not CMake 3.16+. Can we drop support for Amazon Linux 2 in Apache Arrow C++ 13.0.0? FYI1: Amazon Linux released a new version (Amazon Linux 2023) on 2023-03-15: Amazon Linux 2023, a Cloud-Optimized Linux Distribution with Long-Term Support https://aws.amazon.com/blogs/aws/amazon-linux-2023-a-cloud-optimized-linux-distribution-with-long-term-support/ FYI2: Amazon Linux 2 was scheduled to reach EOL on 2023-06-30 but has been extended to 2025-06-30: https://aws.amazon.com/amazon-linux-2/faqs/ > Amazon Linux 2 end of support date (End of Life, or EOL) > has been extended by two years from 2023-06-30 to > 2025-06-30 to provide customers with ample time to migrate > to the next version. FYI3: We'll support Amazon Linux 2023 in Apache Arrow C++ 13.0.0: https://github.com/apache/arrow/pull/36081 Related issue: [C++] Require CMake 3.16 or later https://github.com/apache/arrow/issues/34921 Thanks, -- kou
