Subject: [Buildroot] [PATCH 1/3] package/libabseil-cpp: enforce C++11
Date: Tue, 27 Oct 2020 18:40:44 +0100	[thread overview]
Message-ID: <20201027174046.17157-2-buildroot@heine.tech> (raw)
In-Reply-To: <20201027174046.17157-1-buildroot@heine.tech>

From: Michael Nosthoff <buildroot@heine.tech>

For gcc < 6 the c++ default is 98. Abseil needs at least 11
but doesn't enforce this anymore. So we need to do this.
