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.
