Subject: [Buildroot] [PATCH v6 7/9] package/opencv3: fix CMAKE_CXX_FLAGS
Date: Sun, 16 Oct 2016 13:12:43 +0200	[thread overview]
Message-ID: <20161016111245.1847-8-s.martin49@gmail.com> (raw)
In-Reply-To: <20161016111245.1847-1-s.martin49@gmail.com>

From: Max Filippov <jcmvbkbc@gmail.com>

The commit 4904c4c "package/opencv3: use BR2_TOOLCHAIN_HAS_LIBATOMIC"
overrides CMAKE_CXX_FLAGS with the single -latomic, losing all ABI
CFLAGS that are passed there by default. This breaks build on xtensa
where ABI CFLAGS contain important code generation options.

Append $(TARGET_CXXFLAGS) to CMAKE_CXX_FLAGS along with -latomic.
