Paid support is available until May 2030: https://ubuntu.com/blog/ubuntu-20-04-lts-end-of-life-standard-support-is-coming-to-an-end-heres-how-to-prepare > Should we drop it for DTS? > > Asking because the recent patch to handle shadow warnings doesn't work on > compilers like Gcc 9.4 which don't know what -Wshadow is. Our current minimum GCC compiler requirement is version 8.0: https://git.dpdk.org/dpdk/tree/doc/guides/linux_gsg/sys_reqs.rst#n32 Which GCC version is required to support -Wshadow, and which GCC versions are included in relevant distros? Maybe the -Wshadow can be added conditionally, depending on compiler version. Shadow variables will not be caught locally, if using an old compiler version. But the CI will catch them in the tests running on recent compiler versions.
