__ builtin___snprintf_chk Not Supported

Error Information

1

error: no member named '__builtin___snprintf_chk' in

Problem

Currently, Clang cannot check the formatted output of built-in functions. A warning is reported. When the -Werror option is enabled, the warning is escalated to an error.

Solution

Add -Wno-builtin-memcpy-chk-size to compiler options to avoid the alarm.
