From 5f0ce2333f7e11a3ffb5d16a27cd9303efa712d5 Mon Sep 17 00:00:00 2001 From: Oliver Wolff Date: Tue, 6 Jun 2017 09:43:13 +0200 Subject: [PATCH] Remove -permissive- flag from MSVC 2017 build The flag makes the build fail for UWP as well as desktop Windows . It will trigger a compile error as soon as UWP API is used, which happens in qtbase for desktop in the direct2d backend, but it is also used for other Qt modules, so we decided to disable the flag for now.
