Subject: [PATCH v2] build: announce requirement for C11
Date: Wed,  3 May 2023 18:30:22 +0100	[thread overview]
Message-ID: <20230503173022.22160-1-bruce.richardson@intel.com> (raw)
In-Reply-To: <20230503151413.14915-1-bruce.richardson@intel.com>

Add a deprecation notice informing users that we will require a C11
compiler from 23.11 release onwards. This requirement was agreed by
technical board to enable use of newer C language features, e.g.
standard atomics. [1]

 Deprecation Notices
 -------------------
 
+* C Compiler: From DPDK 23.11 onwards,
+  building DPDK will require a C compiler which supports the C11 standard,
+  including support for C11 standard atomics.
+
+  Please note:
+
+  * C11 is supported from GCC version 5 onwards, and is the default language version in that release
+  * C11 is the default compilation mode in Clang from version 3.6
+
 * kvargs: The function ``rte_kvargs_process`` will get a new parameter
   for returning key match count. It will ease handling of no-match case.
