From 9694305ae0b2a7dbdcc74e2c646d392ceed9876f Mon Sep 17 00:00:00 2001 From: Thomas Petazzoni Date: Sat, 20 Aug 2016 16:00:36 +0200 Subject: [PATCH] pinentry: fix build issue with gcc 5.x pinentry currently fails to build with gcc 5.x, because it uses some functionality from std::string that requires C++11 without passing the appropriate -std= value. We fix this by passing a proper -std= option when gcc >= 5.x. Note that this can be removed once pinentry is bumped to the newest version (currently 0.9.7) because they no longer use std::string in the Qt part. Fixes: http://autobuild.buildroot.net/results/6ea64f692acaebc4d58f3371c632b5121500f17e/ (and many, many similar build failures) Signed-off-by: Thomas Petazzoni One-beer-granted-to: Yann E.
