From 1abe87383e1529a14498d70a0cf445728b9c338d Mon Sep 17 00:00:00 2001 From: =?utf8?q?Kai=20Wasserb=C3=A4ch?= Date: Sat, 17 Aug 2019 10:59:43 +0200 Subject: [PATCH] build: Bump C++ standard requirement to C++14 to fix FTBFS with LLVM 10 MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit When building Mesa against a recent LLVM 10 with C++11, the build fails if the AMD common code is built as well due to "std::index_sequence" being undeclared. LLVM requires a minimum of C++14.
