Subject: [Buildroot] [PATCH] gcc/gcc-final: pass TARGET_ABI flags to configure with --enable-cxx-flags
Date: Tue, 26 May 2015 10:32:36 +0300	[thread overview]
Message-ID: <1432625556-14611-1-git-send-email-jcmvbkbc@gmail.com> (raw)

libstdc++ is in all regards a normal library, it needs to be built with
TARGET_ABI flags, otherwise linking it with other C++ code may fail.

Pass TARGET_ABI flags to gcc-final configure script in the
--enable-cxx-flags parameter.

Fixes:
