Subject: [Buildroot] [PATCH] package/opencv3: fix CMAKE_CXX_FLAGS
Date: Wed, 28 Sep 2016 11:40:32 -0700 [thread overview]
Message-ID: <1475088032-30321-1-git-send-email-jcmvbkbc@gmail.com> (raw)
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.
Fixes:
