Subject: [Buildroot] [PATCH] package/proj: fix build failure due to gcc bug 68485(C++)
Date: Tue, 31 Dec 2019 16:09:57 +0100 [thread overview]
Message-ID: <20191231150957.122179-1-giulio.benetti@benettiengineering.com> (raw)
The proj package exhibits gcc bug 68485 when building for the Microblaze
architecture C files(already fixed), but also for C++ files.
As done for other packages in Buildroot work around this gcc bug by
setting optimization to -O0 when compiling C++ files too if
BR2_TOOLCHAIN_HAS_GCC_BUG_68485=y.
Fixes:
