Subject: [PATCH] Check for -fstack-protector
|
|
|
|
Not all toolchains provide support for -fstack-protector. This patch
|
|
provides a configure check to avoid build errors like
|
|
|
|
/home/buildroot/buildroot/output/host/opt/ext-toolchain/bin/../lib/gcc/x86_64-buildroot-linux-uclibc/6.4.0/../../../../x86_64-buildroot-linux-uclibc/bin/ld: cannot find -lssp_nonshared
