Subject: [Buildroot] [PATCH 1/2] gcc: preserve CXXFLAGS_FOR_TARGET
Date: Fri, 11 Mar 2016 03:45:21 +0300 [thread overview]
Message-ID: <1457657122-7283-2-git-send-email-jcmvbkbc@gmail.com> (raw)
In-Reply-To: <1457657122-7283-1-git-send-email-jcmvbkbc@gmail.com>
gcc-4.8.x and gcc-4.9.x don't propagate CXXFLAGS_FOR_TARGET to CXXFLAGS
for libstdc++ build. As a result libstdc++ is built without
TARGET_CFLAGS and may fail to link with applications using it, see e.g.
http://autobuild.buildroot.net/results/81a3bca5cbcf789c7ce1aa221a6a4154dd7c3917/
Instead of passing TARGET_ABI or TARGET_CFLAGS for libstdc++ in
--enable-cxx-flags parameter backport the patch that fixes propagation
of CXXFLAGS_FOR_TARGET to CXXFLAGS.
