Subject: [PATCH] configure.ac: fix build without stack-protector
|
||
|
|
|
||
|
|
Compiler based hardening (including -fstack-protector-strong) are
|
||
|
|
enabled since version 3.0.3 and
|
||
|
|
https://github.com/lxc/lxc/commit/2268c27754152aa538db2c9e3753d72d19bcd17a
|
||
|
|
|
||
|
|
However, some compilers could missed the needed library (-lssp or
|
||
|
|
-lssp_nonshared) at linking step so use ax_check_link_flag instead of
|
||
|
|
ax_check_compile_flag
|
||
|
|
|
||
|
|
Fixes:
